Overview
Specifications

TR-81 has been designed to be used with any three-wired platinum resistance type (Pt100-type or JPt 100-type) sensor.
The measuring range with a Pt-100 sensor is between -200°C and 600°C and it is possible to attach and measure with two sensors.
Moreover, we can tailor the sensor's protection pipe length, protection pipe diameter and cable length to suit your needs.
