When a temperature calibration application requires a “quick check” or involves smaller sensors, the Isotech range of Fast Calibrators are an ideal choice. There are two handheld temperature calibrators “Quick Cal” covering -12°C to 350°C.

The Fast-Cal range have larger calibration volumes and greater accuracy and well suited to portable operation. The temperature range spans -35°C to 650°C. Fast-Cal models are widely used for validation of washer disinfectors, steam sterilisers and autoclaves.
