80TK, temperature measurement module en Łódź, Polonia

Module compatible with any multimeter having an input impedance of 10MΩ or greater and a DC voltage range of mV. Allows you to turn any Fluke multimeter into a thermometer via a standard banana connector.
Allows use of sensors with type "K" thermocouples." Selects between °C and °F.
The FLUKE 80TK is a Thermocouple Converter for use with any K-type thermocouple and a digital multimeter. The 80TK accepts the output of any K-type thermocouple and converts it to 1mV per degree (Celsius or Fahrenheit). A three-position switch acts as a power switch as well as selecting Fahrenheit or Celsius scaling for the output. In addition, the OFF position of the power switch allows you to read the battery condition via the external multimeter. The thermocouple input accepts wire leads or standard mini thermocouple connectors. Temperature is measured by exposing or attaching the thermocouple to the surface to be measured.
