The KM20REF high accuracy reference thermometer is used to check the calibration and accuracy of probes and thermometers. The thermometer has a temperature range of -100°C to +199.9°C and comes with a 5-Point UKAS calibration certificate at -18°C, 0°C, +8°C, +20°C, +70°C.

To measure the accuracy of another temperature device against the reference thermometer, place both thermometers in a glass of water, place both probe tips into the water and leave for 30 seconds, once the reference thermometer has stabilised, the food thermometer reading can be taken and any necessary adjustment can be made.
