Fluke 4180 Precision Infrared Calibrator Repair
The Fluke 4180 (Hart Scientific) is a precision infrared calibrator — a flat-plate temperature-controlled radiating target that presents an accurate, known surface temperature to calibrate infrared thermometers and thermal imagers. Its precision depends on the temperature-controlled radiating target, the temperature control and reference sensor, and the surface emissivity, which is where service and calibration focus.
FlukeServiceCenter.com repairs and calibrates the Fluke 4180 for thermal-imaging professionals, calibration labs, and predictive-maintenance teams.
Common Fluke 4180 problems we fix
- Output-accuracy / heating faults — won’t reach the setpoint or the target temperature is inaccurate, the heating system repaired and recalibrated against standards.
- Temperature-controller drift — the controller or reference sensor reading wrong, recalibrated.
- Target-surface / emissivity faults — a degraded radiating surface skewing IR calibration, serviced.
- Stability faults — the target temperature not holding stable, the control loop corrected.
- Display, interface, or power faults.
FAQs
My 4180 target temperature is off — fixable? Yes. Heating, control, and surface faults are repairable, then it’s recalibrated so the target temperature is accurate and stable, with a NIST-traceable certificate.
Is the target verified? Yes — target temperature and stability are verified against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
