Temperature Dry Wells ( -40 to 400° C)

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.

GE 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 -40 to 140° C or -25 to 140° C.

Liquid Temperature Baths ( -80 to 150° C)

CTR-80 ( -80 to 30° C)

The CTR-80 bath is the ideal unit for calibrating temperature sensors used in freeze dryers, freezers, and cryo units. Operating from -80 to 30° C, the CTR-80 brings fast response and high stability to your cold temperature applications. With a cool-down time of 120 minutes from ambient to -80° C, and a stability and uniformity of ± 0.03° C, the CTR-80 outperforms all other low temperature baths in its class.

For thermal validation applications, you can save more time by using the CTR-80 with a Validator® 2000 system. The Validator 2000 sets the CTR automatically to your calibration points, determines stability and deviation, and corrects sensor offsets.

Important Features
• 120-minute cool-down time from 30 to -80° C
• large capacity for multiple and different size sensors
• stability and uniformity of ± 0.03° C
• indicates temperature to 0.01° C resolution
• automates calibration when used with the Validator 2000
• quiet operation

CTR-40 ( -40 to 150° C)
The CTR-40 features many of the same design element as the larger CTR-80( above) . It' s operating range of -40 to 150° C covers the majority of thermal process applications with excellent stability and uniformity. The liquid bath configuration is especially well suited for use with the ValProbe system.

Important Features

• stability to ± 0.005° C
• uniformity to ± 0.01° C
• large capacity to handle up to 8 ValProbe Loggers
• immersion basket simplifies loading and ensures proper sensor positions
• benchtop size
• quiet operation
