The AccuMac AM1642 Full Immersion PRT features a unique design that allows for the probe and its lead wire to be used in a high temperature environment such as ovens or furnaces.

It provides an accuracy of ±0.04°C at 0°C, a short term stability of ±0.02°C and fast response time of 5 seconds. AccuMac uses a uniquely designed support structure and filling material to balance between the hysteresis effect, mechanical shock, and thermal shock performance.
