HTR-400
Dry Block Calibrator for extended high Temperature Range

htr400.PNG

Used for applications ranging from 50°C to 400°C such as:

  • Autoclave/ Steam Sterilizers

  • Dry Heat Tunnel/ Oven

  • Washer Disinfector

  • Fermenter

  • Steam-in-Place

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.
