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

±
±

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.
