For over 25 years Kaye has offered the HTR-400 Dry Block Calibrator for the calibration and verification of temperature sensors. While this unit has served our customers well, the technology is outdated, and availability of parts and servicing have become challenging. In order to offer customers the best instruments and continue as the industry standard, Kaye has spent time developing and offering a new dry block calibrator to replace the outdated unit. The HTR-420 is now available and offers expanded functionality such as sensor capacity, efficiency, and performance.

The HTR-400 temperature reference is a dry well specifically designed to fully automate sensor calibration when used with Kaye validation software and traceable temperature standard.

The Kaye HTR-400 dry well employs unique inserts which minimize cooling of the thermocouple tips due to heat conduction,  providing an uncertainty of 0.1°C. Without proper inserts, transfer uncertainty in excess of 0.5°C can occur with 22 gage, type T thermocouples.The HTR 400 features fast heat up and cool down, a capacity to hold up to 24 thermocouples and requires no messy oils.
Calibrating sensors in the environment where they will be used provides the highest degree of accuracy as system temperature coefficient errors are eliminated. The HTR 400 is lightweight and rugged so you can calibrate sensors almost anywhere.

• Fast heat up and cool down
