The Fluke 80TK Thermocouple Module is an external converter that allows any digital multimeter (DMM) with a input impedance and a millivolt (mV) DC scale to function as a thermometer. It accepts input from any Type-K thermocouple and converts the temperature into a voltage signal of per degree (Celsius or Fahrenheit), which is then displayed directly on your multimeter.
