-20 to 760℃ (-4 to
1400℉)
The supplied thermocouple is rated for 250℃ (482℉) maximum. If a
higher temperature range is needed, acquire a suitably rated ther-
mocouple. If a higher temperature is measured with the supplied
probe, damage to the thermocouple and meter is possible.
Specification does not include probe accuracy
