Fluke 51 Thermometer Calibration and Repair
The Fluke 51 is a handheld single-input digital thermometer for thermocouple probes, reading temperature with high accuracy for HVAC, food-safety, and field work. Its accuracy depends on the thermocouple input(s), the cold-junction reference, and the measurement electronics, which is where repair and calibration focus.
FlukeMeterRepair.com repairs and calibrates the Fluke 51 for HVAC, food-safety, lab, and field technicians.
Common Fluke 51 problems we fix
- Cold-junction / reference drift — the cold-junction reference reading wrong, recalibrated against standards.
- Thermocouple-input faults — a channel not reading correctly, repaired.
- Reading inaccurate or out of spec — measurement drift, recalibrated.
- Display or interface faults — repaired.
- Battery or input-jack faults.
FAQs
My 51 reads temperature wrong — fixable? Yes. Input and reference faults are repairable, then the thermometer is recalibrated so it reads accurately, with a NIST-traceable certificate.
Are the inputs verified? Yes — each channel is checked against our temperature standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
