The AccuMac AM1620 precision industrial PRT features an accuracy of ±0.035°C at 0.01°C and a short term stability of ±0.01°C. The sensing element is designed to protect the platinum sensing wire from contamination at high temperatures, giving the device a high level of stability and repeatability. A uniquely designed support structure and filling material provides an excellent balance between the hysteresis effect, mechanical shock, and thermal shock performance.

These probes conform to the standard 385 curve so that the resistance ratio of the PRT follows the DIN/IEC-751 curve precisely.
