Calibration BathTemperature

Electronic controllers which automatically, quickly and with the help of a liquid to supply a temperatureDue to the high reliability, accuracy and exceptional homogeneity in the measuring chamber, this type of instrument is particularly suitable as a factory/working standard for the automatic testing and/or calibration of the widest range of temperature sensors - independent of diameter.

Calibration instrument Due to unparalleled performance characteristics and low measurement uncertainties these instruments are used for calibration in industry (laboratories, production, workshops), in calibration service companies and in quality assurance.

Proven principle

Reliable data

Easy function

Worldwide acceptance

The calibration baths are equipped with electric resistance heating for producing high temperatures. For cooling down, the model CTB9430 is additionally equipped with compressor cooling. The powerful combined pressure and vacuum pump produces very quick and uniform mixing the medium.

The Fuzzy control allows a high temperature stability and a quick controlling of the set temperature even under hard ambient conditions. Therefore the temperature can be measured easy, quick and reliable with an external reference thermometer.

Easy and ergonomic handling (Thermostat can be turned and positioned on all four sides on the bath for easy viewing). Over “pressure buttons” the set temperature can easily be set. If the set temperature is stable the thermometer can be calibrated with the help of an external reference thermometer.

All units are UL/CSA compliant, assuring safe operation in the unlikely event of a fault condition. Different voltage versions are available.
