Fluke 51 Thermometer Repair and Calibration
The Fluke 51 is a precision handheld digital thermometer — a single-input thermocouple thermometer that measures temperature quickly and accurately for HVAC, industrial, and lab use. Its accuracy depends on the thermocouple input and measurement circuit, so that’s where repair and calibration focus.
June Company repairs and calibrates the Fluke 51 for HVAC, industrial, and lab technicians.
Common Fluke 51 problems we fix
- Temperature readings out of spec — reference or measurement drift, recalibrated against standards.
- Thermocouple-input faults — the input not reading the probe correctly, repaired.
- Reading unstable or noisy — measurement-circuit faults, repaired.
- Display segments missing or dim — display faults, repaired.
- Won’t power on — battery/power faults.
