Kaye HTR & LTR Series Uniform Dry Wells

NEW ! LTR-90

 

The HTR and LTR Series temperature references are dry wells specifically designed to fully automate sensor calibration when used with GE Kaye validation software and traceable temperature standards.

 

Kaye dry wells employ unique inserts which minimize cooling of the thermocouple tips due to heat conduction providing an uncertainty of merely 0.1°C. Without proper inserts, for example, transfer uncertainty in excess of 0.5°C can occur with 22 gage, type T thermocouples.

 

Both the HTR and LTR series models feature fast heat up and cool down, a capacity to hold from 18 to 24 thermocouples and require 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 references are lightweight and rugged so you can calibrate sensors almost anywhere.

 

The HTR-400 with an operating range from 25°C above ambient to 400°C is ideal for calibrating sensors for autoclaves, dry heat ovens and sterilization tunnels. For freezers, cold rooms, incubators, and autoclaves, select from the LTR series of dry wells with operating ranges of -95 to 140°C or -25 to 140°C.

The HTR 400 is ideal for high-temperature applications such as autoclaves, dry heat ovens and sterilizer tunnels.

The LTR models offer low-temperature performance for applications including freezers, cold rooms, incubators and autoclaves. The LTR model selection should be based on the application’s low-temperature point.
