Fluke 80T-150U Universal Temperature Probe

Overview

The Fluke 80T-150U is a self-contained temperature-to-voltage converter probe designed to deliver direct temperature readings when connected to any high-impedance DMM with 1 mV resolution and at least 300-count full scale capability. The unit comprises two separate but interconnected assemblies: a temperature-sensing probe and a converter unit connected by a 46-inch cable.

The converter features a three-position power switch that selects Celsius or Fahrenheit scaling, with output of 1 mV per degree. It operates from a standard 9V battery, typically delivering over 600 hours of continuous operation with an alkaline battery. The converter includes an OFF switch to conserve battery life.

Key Features

• Temperature-to-voltage converter: 1 mV per degree output
• Switchable Celsius or Fahrenheit scaling
• Operating range: -50 to 150°C or -58 to 302°F
• High-impedance DMM compatible (1 mV resolution, 300+ count required)
• Voltage standoff: 60V DC or 30V AC RMS (42.4V peak)
• 46-inch cable connecting probe to converter
• Banana plug connectors with 0.75-inch standard spacing
• 9V battery powered (600+ hours with alkaline battery)
• OFF switch for battery conservation
• Battery condition indicator function

Applications

• Temperature measurement in low voltage DC (below 60V) and AC (below 24V) systems
• Direct measurement of non-corrosive liquids, gases, and solids
• Field testing with portable DMM equipment
