Accumac / Probe / AM1730 Secondary Reference PRT

AM1730 Secondary Reference PRT

· Affordable reference probe

· Accuracy ±0.015 °C at 0.01 °C

· Temperature range: -200 °C to 420 °C

· Customized dimensions available

· Temperature range: -200 °C to 670 °C


AM1730 series Secondary Reference PRT provides our customers an affordable reference probe for precision temperature measurement and calibration in labs and fields. The PRT features accuracy of ±0.015°C, short term stability of ±0.007°C. Two different lengths of PRTs are available at 9-inch and 12-inch.

To reach the best performance in stability and repeatability, the sensing element is specially designed to protect the platinum sensing wire from contamination at high temperature. A unique support structure and filling material provide the best balance among the hysteresis effect, mechanical shock and thermal shock performance. This high performance probe meets ITS-90 criteria of reference thermometer fully.
