Description

  • Affordable reference probe
  • Accuracy ?0.015 ?C at 0.01 ?C
  • Temperature range: -200 ?C to 420 ?C
  • Customized dimensions available

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.
