The AM1760 series Secondary SPRTs provides our customers with reliable secondary standards that can be used daily in their labs.
AM1762/AM1760 have a temperature range from -200 °C to +670 °C.
This SPRT features accuracy of ±0.006 °С at 0.01 °C , short term stability of ±0.002°C and very low drift rate of less than 4 mK after 100 hours at +661 °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.
