Precision instruments, calibrated and ready to work.

Pressure Gauges

Digital pressure gauges for field and lab work — Crystal, Additel, Ralston, and related instruments, with ISO/IEC 17025 accredited calibration available on most models. ## What a pressure gauge does A pressure gauge gives you a local reading of pressure at the point of measurement. Digital gauges use a sensor and display so you can read resolution clearly, switch units, and (on many models) log data or send an output — useful for leak checks, calibration work, and process checks where an analog dial is hard to resolve. ## Gauge, absolute, and differential - **Gauge pressure** is referenced to atmosphere (most process readings). - **Absolute pressure** is referenced to vacuum (includes atmospheric effects). - **Differential pressure** compares two ports (filters, flow elements, DP tests). Match the sensor type and range to the job; do not rely on a gauge past its rated pressure. ## Choosing a digital gauge - **Range and accuracy** — pick a range that covers the work with margin; tighter accuracy costs more and may need a piston/deadweight reference for cal. - **Output / logging** — needed when you record as-found/as-left data or feed a recorder. - **Environment** — intrinsically safe, weather sealing, and media compatibility when the process demands it. - **Process connection** — NPT, sanitary, or quick-test adapters so the gauge connects cleanly to the UUT or process. ## Brands we stock in this category - **Crystal (AMETEK)** — XP2i / XP3i and related reference gauges for portable high-accuracy work. - **Additel** — digital gauges across wide ranges, including IS and logging options. - **Ralston** — field gauges and process meters that pair with Quick-test hoses and fittings. - **REED** — manometers for lower-cost differential and HVAC-style checks. ## Calibration Most gauges here can ship with **ISO/IEC 17025 accredited calibration** from Total Calibration Solutions, with the test data your quality system needs. Ask at quote or checkout if you need as-found data, specific test points, or a due date aligned to your program.

Temperature Calibrators

Dry-block, bath, and furnace temperature calibrators for industrial sensors and transmitters — JOFRA, Additel, and related lines, with ISO/IEC 17025 accredited calibration available on most instruments. ## What a temperature calibrator does A temperature calibrator creates a stable temperature environment so you can compare a thermometer, RTD, thermocouple, or transmitter against a known reference. Dry-wells (dry-blocks) are common in the field; baths and furnaces cover wider or higher ranges. ## Dry-well, bath, and furnace - **Dry-block / dry-well** — portable or benchtop inserts for sensors; fast and clean for many industrial jobs. - **Liquid baths** — better uniformity for some lab comparisons (when available in-line). - **Furnaces / high-temp blocks** — thermocouple and high-temperature work (e.g. Additel furnace platforms). ## Choosing a calibrator - **Range and stability** — cover the UUT with margin; watch axial gradients on inserts. - **Insert / well diameter** — must fit your probes without excessive air gap. - **Reference probe inputs** — when you use an external SPRT/RTD reference. - **Documenting / automation** — useful for multi-point procedures and paperless as-found/as-left. ## Brands in this category JOFRA (AMETEK) dry-wells and related temperature calibration tools, Additel temperature calibrators and furnaces, plus accessories called out on each product page. ## Calibration Most temperature calibrators here can ship with **ISO/IEC 17025 accredited calibration**. Specify range, points, and whether you need the reference probe on the same certificate.

Temperature Indicators

Reference thermometer readouts and digital temperature indicators for precision temperature measurement — pair with reference probes and calibrators. ## What an indicator does A temperature indicator / readout measures the signal from an RTD or thermocouple and displays temperature with higher resolution and better uncertainty than a basic DMM. Many models support probe characterization and documenting. ## Choosing a readout - **Sensor inputs** — RTD, thermocouple types, and channel count. - **Accuracy / resolution** — must support your TUR with the probe you use. - **Portability** — field handheld vs benchtop. - **Probe library / coefficients** — important when you use calibrated reference probes. ## Pairing Use with **Temperature Sensors** and **Temperature Calibrators**. Product pages list compatible probes where OEM documentation is clear. ## Calibration Indicators can usually ship with **ISO/IEC 17025 accredited calibration**. Calibrate the indicator and probe as a system when your procedure requires it.

Temperature Sensors

Reference sensors, DLC probes, and temperature modules used with dry-wells, baths, and readouts — JOFRA, Additel, and related lines. ## Role of the reference sensor A temperature calibrator creates the environment; the **reference probe** (or the calibrator’s internal sensor) is what you trust for comparison. Better probes and proper immersion improve uncertainty. ## Common types - **Reference RTDs / SPRTs** — low uncertainty laboratory and industrial references. - **Thermocouples** — higher temperatures and rugged industrial checks. - **DLC / special probes** — application-specific inserts and sensors called out by OEM. - **Temperature modules** — plug-in sensors for multifunction platforms. ## Selection tips Match **diameter and length** to your dry-well insert, confirm the **connector** on your readout, and pick a range that covers the UUT with margin. ## Calibration Reference sensors and modules can usually ship with **ISO/IEC 17025 accredited calibration**. Request points that match your procedure.

Process Calibrators

Multifunction and loop calibrators for mA, voltage, thermocouple, RTD, frequency, and related process signals — Additel, PIE, and complementary tools, with ISO/IEC 17025 accredited calibration available on most instruments. ## What a process calibrator does A process calibrator sources and/or measures the electrical signals used in industrial control loops so you can check transmitters, I/O, and controllers without the full process running. Multifunction models combine several signal types in one handheld. ## Common jobs - **4–20 mA loops** — source, simulate, and measure with or without loop power. - **Temperature signals** — thermocouple and RTD simulate/measure for transmitter and control checks. - **Voltage / frequency** — for a wide range of sensors and discrete checks. - **Diagnostics** — leak/fault finding features on documenting models (including PIE diagnostic tools where offered). ## Choosing a calibrator - **Signals required** — mA-only vs multifunction (TC/RTD/V/Hz). - **Documenting vs basic** — as-found/as-left storage and PC download. - **HART / fieldbus** — only when your installed base needs it (check each model). - **Intrinsic safety** when the area classification requires it. ## Brands in this category Additel documenting process calibrators, **PIE** handheld process calibrators (loop, TC, RTD, multifunction), and related accessories. Pressure work often pairs with our Pressure Calibrators and Gauges categories. ## Calibration Most process calibrators can ship with **ISO/IEC 17025 accredited calibration**. Tell us which functions and ranges matter for your procedure.

Pressure Calibrators

Handheld and automated pressure calibrators for generating or controlling pressure and comparing it to a reference — Additel, Crystal, and related lines, with ISO/IEC 17025 accredited calibration available on most instruments. ## What a pressure calibrator does A pressure calibrator helps you apply known pressure to a gauge, transmitter, or switch and document as-found / as-left performance. Depending on the model, that can mean a hand pump plus a reference gauge, a documenting calibrator, or an automated controller that sets pressure for you. ## Handheld vs automated - **Handheld / documenting calibrators** — portable for field loops, often combine measure/source and document results. - **Automated pressure controllers / calibrators** — set and hold pressure with higher throughput for shop or lab work. - **Reference gauges** — sometimes used as the comparison standard with a separate pump or controller (see Pressure Gauges). ## Choosing a calibrator - **Range and media** — pneumatic vs hydraulic, vacuum through high pressure. - **Accuracy / uncertainty** — must support the TUR your procedure requires. - **Portability vs throughput** — field kits vs benchtop automation. - **Documentation** — onboard documenting, Bluetooth/logging, or paper worksheets. - **Intrinsically safe** options when the area classification requires them. ## Brands in this category Additel automated and handheld pressure calibrators, Crystal documenting/reference tools, and complementary generation gear. Matching pumps, hoses, and Quick-test fittings are linked from product pages where OEM pairing is clear. ## Calibration Most calibrators here can ship with **ISO/IEC 17025 accredited calibration** from Total Calibration Solutions. Tell us if you need specific test points, as-found data, or alignment to your due dates.

Pressure Controllers

Portable and benchtop automated pressure controllers for setting and holding pressure during calibration and test — primarily Additel, with ISO/IEC 17025 accredited calibration available on most models. ## What a pressure controller does A pressure controller automatically regulates pressure to a setpoint so you can calibrate gauges, transmitters, and switches without manually pumping and venting to each point. That improves speed and repeatability versus hand generation alone. ## Where controllers fit - **Shop / lab benches** — high volume of UUTs, tight setpoints, documenting workflows. - **Portable automated calibrators** — field or satellite shops that still want automated control. - **Complement to pumps and gauges** — controllers often sit between a supply (N2, shop air, or hydraulic) and the device under test. ## Selection tips - **Range and control stability** — match the UUT span with margin. - **Pneumatic vs hydraulic** media and contamination control. - **Accuracy and modules** — external pressure modules when you need extra ranges. - **Throughput features** — leak test, switch test, and documenting options on many Additel platforms. ## Calibration Controllers and associated modules can usually ship with **ISO/IEC 17025 accredited calibration**. Ask at quote if you need module-level certificates or custom points.

Pumps & Generation

Pressure generation for calibration and test — hand pumps, hydraulic kits, volume controllers, and regulators from Ralston, Additel, and related lines. Pair with gauges and Quick-test hoses; ISO/IEC 17025 calibration applies to the measuring instruments more often than to the pump itself. ## What generation gear does Pumps and volume controllers create pressure (or vacuum) so you can exercise a gauge, transmitter, or switch. The pump is the muscle; a reference gauge or calibrator is still the standard. ## Pneumatic vs hydraulic - **Pneumatic hand pumps** — fast for lower pressures and many field checks; watch for moisture/oil in the media path. - **Hydraulic pumps / kits** — higher pressures with oil or water/compatible fluids. - **Volume controllers / fine adjust** — precise tweaking near setpoint once coarse pressure is applied. - **Regulators** — stable supply from bottles or shop air into a calibration setup. ## Building a field kit 1. Choose generation (pump) for the max pressure you need. 2. Add a **reference gauge or calibrator** at the right accuracy. 3. Use **Quick-test / CPF fittings and hoses** so connections are repeatable and leak-tight. 4. Carry spare seals and the correct fluid for hydraulic work. ## Brands in this category Ralston pumps and generation accessories, Additel generation options, and fittings/hoses sold alongside in Fittings & Adapters and Hoses. ## Note on calibration Hand pumps are typically not “calibrated” like a gauge; calibrate the **reference instrument** in the loop. We can include accredited cal on the gauge/calibrator you pair with the pump.

Fittings & Adapters

Quick-test adapters, fittings, elbows, tees, manifolds, fluid traps, and Crystal CPF — the connection hardware that makes pressure calibration kits leak-tight and repeatable. ## Why fittings matter Most calibration delays come from leaks and mismatched threads, not from the gauge. Matched Quick-test / CPF hardware lets you rebuild a setup without wrenches and without damaging soft seals every time you change a UUT. ## What we stock - **Quick-test adapters** — hose-to-NPT, AN, tube, and process connections (Ralston QT/QTHA families). - **Elbows, tees, and manifolds** — benchtop and field distribution of pressure. - **Fluid traps** — protect gauges and controllers from liquid carryover. - **Crystal CPF** — Crystal’s proprietary fitting system for many Crystal gauges and modules. - **Kits** — common adapter assortments for field techs. ## Pairing tip Match the hose and adapter family to the pump and gauge on the product page. OEM-paired accessories are listed under Related products when we have datasheet-backed pairing. ## Note Fittings are typically not ISO/IEC 17025 calibrated; calibrate the **gauge or calibrator** in the loop.

XT variants extend the same idea into higher working pressures where the OEM rating allows. ## Pairing Hoses pair with [pumps & generation](/products/category/pumps-generation) and [fittings & adapters](/products/category/fittings-adapters). Product pages list OEM-compatible ends where known — we do not invent compatibility. ## Note Hoses are not calibrated instruments; keep them clean and within rating, and calibrate the reference gauge or calibrator.

Pressure Modules

External pressure modules for compatible Crystal and Additel calibrators — expand range coverage without buying a second handheld. ## What a pressure module does A pressure module is a remote sensor that plugs into a documenting calibrator, indicator, or controller.

Calibrate the parent meter; replace consumables on the OEM schedule. We do not invent compatibility — only list pairings already named on the accessory page.
