Fluke 80T-150 Temperature Probe

The Fluke 80T-150 is a self-contained temperature-to-voltage converter probe designed for direct temperature measurement with high-impedance Digital Multimeters. It delivers 1 mV per degree Celsius or Fahrenheit output, enabling precise readings on any DMM with 1 mV resolution and minimum 300-count full-scale capability. The probe features a glass-filled Valox body with a nickel-plated copper tip, suitable for non-corrosive liquids, gases, and solid surfaces across its operating range.

The instrument comprises two assemblies: the temperature probe and the converter module, connected by a 46-inch shielded cable. A standard 9V battery supplies power, delivering over 600 hours of typical operation with an alkaline cell. Output termination uses standard 0.75-inch spaced double banana plugs for direct connection to DMM input terminals.
