The Fluke 80T-150UA Universal Temperature Probe is a self-contained temperature-to-voltage converter. The probe is designed to provide a direct temperature reading when it is connected to any high impedance DMM that is capable of 1 mV resolution and at least a 300-count full scale readout capability. Two switch-selected temperature output scalings are provided. The probe will stand off 60V dc or 30V ACrms (42.4V peak).

The unit is housed in two separate but attached assemblies: a temperature probe and a temperature-to-voltage converter. The probe contains the temperature-sensing element and is electrically connected to the temperature-to-voltage converter through a 46 in. cable. A three-position switch on the converter acts as a power switch and is used for selecting Celsius or Fahrenheit scaling for the output.

Temperature is measured by exposing the probe tip directly to the material (non-corrosive liquid, gas, or solid). A direct temperature reading is displayed on the DMM.
