Digital Pressure Gauge Benefits
Ease of Use
The Field Gauge LC10 was developed specifically for simplicity. It is compact in size, but with a large, easy-to-read display showing numbers and bar graphs clearly with a bright backlight for added visibility. The controls are clear and intuitive - there's no guesswork with the Field Gauge LC10. And it's powered by two low cost AA batteries which are easy to replace. Unlike analog gauges, it maintains calibration through shock, vibration, and abuse and will even stay calibrated if the battery dies.Versatility
The Field Gauge LC10 digital pressure gauge allows you to switch quickly and easily from among 15 standard engineering units. Similar products only allow two. And with the included FieldLab Desktop software, you can create custom engineering units, remove unneeded units, and configure other settings quicker and easier than ever. This allows you to truly customize the gauge to your needs, displaying only those units necessary for your application.Durability
Field Gauge LC10 digital gauges are built to last. It's waterproof up to 1 meter (IP67), and because it's digital, there are no mechanical parts that'll wear out and need to be replaced over time. Its rugged aluminum case and built-in screen protector keep the internal components safe, so you can toss it in your bag, drop it, or leave it out in the rain, and it will maintain its accuracy. Certificate of Calibration Not Included - To add Calibration please call with your order -
An affordable panel mounted pressure gauge with high-end features, the new Ralston Instruments Field Gauge LC30 line of digital pressure gauges was designed with the user in mind.

With advanced microprocessor technology and state-of-the-art silicon pressure sensors, the Additel ADT 681 Digital Pressure Gauges provide an accurate, reliable, and economic solution for a wide range of pressure applications. They are loaded with functionality and remarkably easy to use. To reach the best performance, every silicon pressure sensor in our gauges is specially aged, tested and screened before assembly. At Additel, fully temperature compensated accuracy means every sensor is pressure tested at several environmental temperatures from -10°C to 50°C. With this test data individual coefficients are generated and stored in the gauge characterizing its performance over the full temperature compensated range. And now the ADT681IS comes with an IP67 rating meaning it is dust resistant and water proof, submerible in 1 meter of water. Designed to fit your need The Additel ADT 681 Digital Pressure Gauges pressure gauges give you the widest variety of sensor choices on the market. Whether you require low inches of water measurement or very high pressure measurement, we have a gauge that will meet your need. We offer sensors which are ±1 inH2O (±2.5 mbar) to 60K psi (4,200 bar) and everything in between. Do your applications require you to measure both positive and vacuum pressure? Our compound gauges do not compromise accuracy and provide you with the same high accuracy specification on both positive and vacuum pressures. We offer a wide variety up to 300 psi (20 bar). If you need a higher range, just contact us and we can likely customize one to meet your need. We also offer absolute pressure sensors to 5K psi (350 bar) and a full range of differential pressure sensors from ±1 inH2O (±2.5 mbar) to ±300 inH2O (±700 mbar). Are you looking for a pressure gauge to use in hazardous areas? Our certified (ATEX, CSA US & IECEx) intrinsically safe models (681IS) are designed for pressure measurement in hazardous areas. If you need to panel mount our sensors, we offer the option (see ordering information) for a back-mounted pressure port and gauge housing designed to fit in a panel. And most recently, we've added the option to do stand-alone data logging with the 681. Now you can record more than 21,000 records internal to the 681 series. Each record includes date, time, pressure and temperature readings. Download the logged data with our free Additel/Land software or you can purchase our Additel/Log II for real-time logging and data analysis. The 681 series digital pressure gauges are unmatched in performance and reliability. Best of all, they are very affordable. **PRICING BASED ON CONFIGURATION - REQUESTE QUOTE FOR ACTUAL COST **
