AM1760 series Secondary SPRTs provide our customers reliable secondary standards that can be used daily in their labs. This SPRT features accuracy of ±0.006°C at 0.01°C, short term stability of ±0.002°C and very low drift rate of less than 0.004°C after 100 hours at 660°C. Two different lengths of SPRTs are available at 12-inch and 20-inch.

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 excellent balance between the hysteresis effect, mechanical shock and thermal shock performance. This high performance probe fully meets ITS-90 criteria for reference thermometers.
