The MT630 is a single input J/K-type general purpose thermometer with a wide measuring range from K-type –200°C to +1372°C and J- type –210°C to +1100°C with a selectable resolution of 0.1°C or 1°C. The MT630 displays a number of temperature readings such as T1 plus MAX, MIN and AVG. Features include a relative time clock on MAX, MIN and AVG and provides a time reference for major events.

The MT630 (single inputs) contact thermometer offers fast response and laboratory accuracy. This thermometer works with K thermocouples and offer 0.1°C resolution over the entire measurement range. Electronic offset function allows compensation of thermocouple errors to maximise overall accuracy. Readout in °C, °F or Kelvin (K/J)

MT630 is protected with a rugged rubber holster.
