100% reassurance with Hanna Cal Check
Hanna's exclusive Cal Check, saves time and brings peace of mind to users in busy catering environments. In hot kitchens, fast production lines and hectic retail environments, few operators have the time to keep checking the accuracy of their meters.
Hanna Cal Check automatically verifies the thermometer circuit accuracy at 0.0°C every time it is switched on. During start up, the calibration of the thermometers circuit is checked and the result is briefly displayed on the thermometers display to show the operator the calibration result.
Please note: The Cal Check system can only check the electronic circuit calibration and does not check the sensor of the thermometer. For further peace of mind it is recommended to check the sensor by performing an ice test or comparative test against a reference thermometer.
