Calisto is a calibration dry block and liquid bath for temperature thermometers from 30°C (in ambient of 20°C) to 250°C. Combined with accessories, it can also be converted into a Blackbody Source for infrared thermometers, a surface sensor calibrator and ITS-90 Fixed Point cell with calibration uncertainties up to 0.0005ºC.
Calisto is available in two models, the BASIC (B) and the SITE (S).
The B model includes a sophisticated temperature controller with a dual display for set temperature and dry block temperature.
The S model additionally includes an in-built temperature digital indicator to which an external temperature sensor can be connected. It ensures traceability, best practise and adherence to quality standards and calibration to the smallest of uncertainties
For dry block use, the unit under test may be compared to the controller value. The use of an external probe connected to the indicator of the Site model which compensates for the temperature gradient and loading errors, is recommended. This gives greater accuracy and traceability meeting the requirements of ISO 9000 and other quality standards.
For liquid bath, surface sensor and blackbody use, an external standard probe should always be used, either with the S models indicator or a separate stand-alone indicator.
For laboratory use, Calisto can be used with a laboratory performance temperature indicator.
