AccuMac AM1760 & AM1762
Secondary SPRTs
OVERVIEW
The AM1760 series Secondary SPRTs provides our customers with reliable secondary standards that can be used
daily in their labs. These SPRTs feature 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 0.004°C after 100 hours at 661°C. Two different lengths of these SPRTs are available at
either12 inches (305 mm) or 20 inches (508 mm).
The sensing element is designed to protect the platinum sensing wire from contamination at high temperatures, giving
these SPRTs a high level of stability and repeatability in performance. A uniquely designed support structure and lling
material provides excellent balance between the hysteresis effect, mechanical shock and thermal shock performance.
This high performance probe fully meets the ITS-90 criteria for reference thermometers. Each probe comes standard
with an ISO 17025 accredited calibration.
