Overview
The STS Reference Sensors are Pt100 reference probes used as the reference instrument to verify true temperature in any type of hand-held, liquid bath, or dry-block calibrator. Use directly in custody transfer applications where high accuracy means money. The superior specifications combined with a long history of reliability and low drift have made the STS probes the working standard in many national laboratories worldwide.
STS sensors are economical and offer fast response times, low immersion depths, compact physical sizes, and specified low drift rates, even at high temperatures. Combine with JOFRA temperature instruments for complete high-accuracy systems. Series features from the official AMETEK page include a wide temperature range of −100 to 700°C, high system accuracy of ±0.04°C when combined with RTC calibrators, a long-term burn-in procedure up to 650°C, and accredited certificates up to 650°C as standard delivery.
The JOFRA STS-050 A probes are designed for fast and accurate, traceable calibration of temperature. Official AMETEK documentation states STS-050 can be used for measuring and calibration with AMETEK DTI Series, PTC B & C Series, RTC B & C Series, HPC Series, ATMi and ASC series. Official base model: Pt100 reference sensor, solid, with handle, −50 to 400°C (−58 to 752°F). Standard delivery includes an international traceable calibration certificate; an accredited (ISO/EN/IEC 17025) calibration certificate can be selected.
