Surface Transfer Standard (STS) Calibrator for Roller Contact Sensors

Our Surface Transfer Standard (STS) Calibrators for Roller Contact Sensors feature an advanced controller that allows you to fine-tune the temperature with impressive precision, with a resolution of 0.1 °C. Available in both 120VAC and 240VAC versions, the STS calibrators are regularly utilized on production floors, ensuring sensor accuracy remains spot-on before, during, and after each shift. By implementing these instruments, you can eliminate measurement uncertainties and confidently maintain the calibration of your roller contact sensors and pyrometers.

We are thrilled to present our standard range of surface calibrators, which includes the STS-SC1-PRT for high-temperature calibrations and the STS-SC2-PRT for mid-range applications. What sets this product apart is its specific block design, engineered for testing Roller Contact Style Sensors—essential tools for many industrial scenarios. Weighing in at a mere 25 lbs., these portable units effortlessly transition from lab settings to production floors or field locations. The thoughtfully designed 2-inch diameter curved aluminum block provides ample surface area ideally suited for calibrating various roller-style surface sensors, all while accommodating maximum temperature ratings up to 350 °C.

These lightweight, efficient calibrators highlight their superiority over larger, pricier dry wells and unreliable hot plates. Even at the highest temperatures, our STS offers outstanding temperature stability of less than ±0.05 °C. Each EDL calibrator has a NIST Traceable calibration certificate, making the STS line ideal for sensors, digital thermometers, dial gauges, and bulb switches.

The convenient RS-232 interface makes collecting data a breeze and enables downloads to your computer. Our user-friendly iTools software further enhances your experience, allowing for computer-controlled set points that facilitate automatic testing. With their economic price point, straightforward design, ease of use, and compact form, EDL’s calibrators are the original and premier choice among surface calibrators available today.
