Low-temperature calibration bath CTR-40

high-temperaturefor temperature sensorsportable

Description
The CTR-40 is a portable calibration bath designed for calibration and validation of the Kaye ValProbe RT temperature sensor system. Used with the Kaye IRTD and ValProbe RT software, the CTR-40 performs automated calibrations and verifications for ValProbe RT loggers. The unit delivers high temperature uniformity and stability over a −40 to 150 °C range while remaining quiet in operation.
