Thermal calibrator HTR-420

for the pharmaceutical industrydry-blockindustrial

Overview
The Kaye HTR-420 is a high-temperature dry-block temperature calibrator for thermal validation and multi-sensor calibration. It supports simultaneous calibration of up to 48 thermocouples using a dedicated fixture, covers an operating range of 30 °C to 420 °C, and offers high stability and uniformity. The unit integrates with Kaye software for automated routines and can operate standalone via a 7" colour touchscreen.
