AccuMac AM1730
Secondary Reference PRT
OVERVIEW
The AM1730 series of Secondary Reference PRTs offers affordable reference probes for precision temperature mea-
surement and calibration both in the lab and in the eld. These PRTs feature an accuracy of <0.012°C and a short term
stability of <0.007°C.
To reach the best performance in stability and repeatability, the sensing element has been specially designed to protect
the platinum sensing wire from contamination at high temperatures. A unique supporting structure and lling material
provide the best balance among 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.
