Surface Calibrators

EDL's STS Surface Transfer Standard Calibrators were developed for quick and easy calibration of surface sensors. The STS surface block is normally supplied in Aluminum, with a brass block for high temperature calibrations. 

The Aluminum test surface is machined and milled for the smoothest calibrations available with maximum thermal conductivity. The 2" diameter (6.3 sq. inches) test surface is large enough to calibrate multiple sensors at a time. The STS line of surface calibrators is available as a complete reference system for absolute trust in your measurements. 

With a high accuracy of ± 2.0 °C over the whole temperature range (650 °C), you can use the STS to calibrate almost any surface probe, thermistor, thin film sensor, RTD, or thermocouple. Contact our sales team for more information, [email protected].
