The AccuMac AM1762 Secondary SPRT features an accuracy of ±0.006°C at 0.01°C, a short term stability of ±0.002°C and a very low drift rate of less than 19mK after 500 hours. 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 in performance. A uniquely designed support structure and filling material provides an excellent balance between the hysteresis effect, mechanical shock, and thermal shock performance.
