The Isotech Calisto 4953 temperature calibrator can be used as a dry block or liquid bath. Accessories are available 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. With excellent stability and distributed
heating / cooling zones for good uniformity these calibrators offer proven thermal performance and are easy to use.
