The Kaye CTR-25 is the latest addition to our complete line of advanced calibration dry blocks and baths designed to address the specific needs of thermal Validation. The CTR-25 was designed to address portability, capacity, speed and accuracy requirements not normally found in competitive liquid baths.

The CTR-25 is ideally suited for verifications of up to 10 Kaye ValProbe or ValProbe RT Loggers as well as various sized process sensors. Onboard firmware enables automatic real-time verification of RT (real-time) ValProbe Loggers and standard ValProbe loggers. Having a portable, rugged, accurate liquid bath allows customer to easily perform periodic verifications of their Loggers which greatly minimizes risk associated with waiting for yearly factory calibrations.
