Isotech ADVANCED Calisto


These models will calibrate temperature probes from -45° to 250°C with unrivalled flexibility. As a traditional Dry Block,several thermometers can be quickly calibrated.

Accessories are available to convert to a stirred liquid bath,for surface sensor calibration, to calibrate infrared thermometers and even to use as an ITS-90 Fixed Point System with calibration uncertainties as small as 0.0005°C.
