The thermometer with thermocouple type K with high accuracy ±0.5°C, 0.1°C or 1°C resolution over the full range. An additional feature allows the user to adjust the reading to offset any probe errors, correcting any inaccuracies of the thermocouple probe. Each thermometer thereafter will automatically store, display the offset and adjust the instrument for the known probe error, maximising system accuracy.
The GMH 3221 has the versatility of accepting type K thermocouple probe, the unit incorporates both max and min readings with a reset function and also features an auto-power off facility that maximises the battery life, turning the instrument off automatically, this function can be disabled if not required.

An IP rating, also known as "International Protection" or "Ingress Protection" rating, is a value assigned to a product that determines its susceptibility to ingress from solids and liquids. The first numeric digit relates to the level of protection against solid objects, and the second numeric digit indicates the level of protection against liquid ingress. Click for a table of IP Rating values.
