The CALISTO PLUS offers an exceptionally wide operating range in an easy to use portable package. As part of the ISOCAL-6 series the CALISTO PLUS can be used as a Dry Block, a Liquid Bath, a Blackbody Source for infrared thermometers, a Surface Sensor Calibrator and for performance to a few mK (0.001ºC) ITS-90 Fixed Points. The 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 for further details. The S model additionally includes an in-built digital indicator to which an external temperature sensor can be connected.For Dry Block use the unit under test may be compared to the controller value, Isotech recommend the use of an external probe connected to the indicator of the Site model which compensates for the temperature gradient and loading errors. 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 an external indicator, e.g. an Isotech TTI model. For laboratory use the CALISTO can be used with a laboratory performance temperature indicator such as one of the Isotech True Temperature Indicators (TTI). |
