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. Official AMETEK series features 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, special 90° angled probes to make room for sensors under test, and accredited certificates up to 650°C as standard delivery.
Official AMETEK documentation lists the STS-100 as a Pt100 reference probe, solid, −150 to 650°C (−238 to 1207°F). It is one of the STS families shown on the official STS Reference Sensors product page.
