AM1751 series Secondary reference PRT provides our customers an affordable reference probe for precision temperature measurement and calibration in labs and fields.
AM1751 has a temperature range from -200 °C to +670 °C.
The PRT АМ1751 features accuracy of ±0.015 °C at 0.01 °C; short term stability of ±0.007 °C. Two different lengths of PRTs are available at 12-inch and 20-inch.
The sensing element is designed to protect the platinum sensing wire from contamination at high temperatures, giving the device a high level of stability and repeatability in performance. A uniquely designed support structure and filling material provides excellent balance between the hysteresis effect, mechanical shock and thermal shock performance. This high performance probe fully meets ITS-90 criteria for reference thermometers.
