Description
Fluke 52 Thermometer Calibration and Repair
The Fluke 52 is a handheld dual-input digital thermometer for thermocouple probes, reading two channels (and their difference) for HVAC and lab 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 52 for HVAC, food-safety, lab, and field technicians.
Common Fluke 52 problems we fix
- Dual-input / differential faults — one of the two channels not reading or the differential function wrong, repaired and recalibrated.
- Cold-junction / reference drift — the reference reading wrong, recalibrated against standards.
- Reading inaccurate or out of spec — measurement drift, recalibrated.
- Display or interface faults — repaired.
- Battery or input-jack faults.
FAQs
My 52 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.
