Industrial Calibration - Temperature Dry Blocks

Advanced Range

The ADVANCED range of Dry Blocks and Multi-Function Calibrators have extra features and improved performance over the Isotech BASIC and SITE Models. Benefits include up to three input channels, advanced logging and full colour display

Multi Function Calibrators

These models cover from -45°C to 250°C with unrivalled flexibility. Use as a Dry Block, A stirred liquid bath, Ice Point, Surface Sensor calibration, Infrared thermometers Calibrator and even use as an ITS-90 Fixed Point System.

Dry Block Calibrators

Dry blocks covering from -100°C to 1200°C. Portable with a range of calibration volumes offering immersion depth from 100 to 300mm.


Fast Calibrators

FAST-CALs work from -35°C to 650°C in three ranges offering cost effective, fast and portable calibration. Also two Handheld Quick-Cal models.


A six decade resistance box for RTD simulation and high accuracy Thermocouple simulator that can measure and source.
