Each of the aforementioned models has a temperature range of -35°C to +140°C and supports the following six modes of operation:

Dry Block/ Metal Block Bath (default)
Stirred Liquid Bath
Stirred Ice/ Water Bath
Blackbody Source
Surface Sensor Calibrator
ITS-90 Fixed Point (this mode can provide an uncertainty of 0.0005°C)

Please note that additional accessories are required to enable operation in Stirred Liquid Bath, Stirred Ice/ Water Bath, Blackbody Source, Surface Sensor Calibrator and ITS-90 Fixed Point modes.

When used as a traditional dry block, the Isotech Isocal 6 Venus 4951 can calibrate several thermometers simultaneously. It calibrates the entire measurement loop and provides excellent stability, as well as distributed heating and cooling zones for good uniformity, enabling it to deliver excellent thermal performance. It also has a calibration volume of 35mm x 160mm and features fast heating and cooling times. Please see the video below for further information regarding Isotech’s 4000 series.
