The CEM DT-610B/DT-612 Digital Thermometers are portable hand held and compact meters designed to use an external K type thermocouple as a temperature sensor. Temperature indication follows N.I.S.T and I.E.C. 584 temperature/voltage tables for K type thermocouples. They have user selectable °C/°F/K scales and resolution of 0.1/1 °C/°F/K.
