Fluke 51 II Handheld Digital Probe Thermometer
Temperature often reveals the real fault. A loose connection warms up, a motor runs hot, or an enclosure hides a developing issue. The Fluke 51 II Handheld Digital Probe Thermometer helps you measure contact temperature quickly and accurately, so you can make decisions based on data instead of guesses. It delivers fast response with laboratory-level accuracy and keeps the readout clear on a large backlit display.
Use common thermocouple types across many jobs
The Fluke 51 II supports J, K, T, and E-type thermocouples. That flexibility matters because different probes suit different surfaces and environments. So you can check motors, breakers, pipes, liquids, and wiring with the probe that fits the task, while the thermometer keeps operation simple and consistent.
Spot peaks and dips, not just one moment
Single readings can lie when loads fluctuate. The 51 II includes Min, Max, and Avg functions, plus a relative time clock that adds context to major events. That means you can see a peak temperature during start-up, then compare it with normal running conditions. As a result, you can diagnose overheating that appears intermittently and avoid returning to site with the same question later.
Stay productive with a rugged, field-ready build
The 51 II suits field work. It comes protected by an impact-absorbing holster, and the case resists splashes and dust. It also runs on three AA batteries and delivers typical 1000-hour battery life, which helps when you rely on it daily. The battery door design lets you replace batteries without breaking the calibration seal, so you keep downtime low.
A practical thermometer for maintenance and testing
If you need a reliable contact thermometer for HVAC, process work, food safety checks, or general maintenance, the Fluke 51 II fits the role. It keeps controls straightforward, readings clear, and performance consistent, so you can measure, log the result, and move forward.
