Fluke 80TK Calibration

Description

Fluke 80TK Thermocouple Module Calibration and Repair

The Fluke 80TK is a thermocouple-to-voltage converter module — it accepts a K-type thermocouple and outputs a scaled millivolt signal (1 mV/°), letting any standard multimeter read temperature. Its accuracy lives in the cold-junction reference and the conversion circuitry, which is where service and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke 80TK for HVAC, electrical, and field technicians.

Common Fluke 80TK problems we fix

• Cold-junction / reference drift — the temperature conversion reading wrong, recalibrated against standards.
• Output-scaling faults — the mV-per-degree output out of spec, recalibrated.
• Thermocouple-input / jack faults — a damaged input giving erratic readings, repaired.
• Output-lead faults — repaired.
• Battery faults — serviced.

FAQs

My 80TK reads temperature wrong — fixable? Yes. Reference and conversion faults are repairable, then the module is recalibrated so its output is accurate, with a NIST-traceable certificate.

Is the output verified? Yes — checked against our temperature standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
