Fluke 4181 IR Calibrator Repair

Description

Fluke 4181 Infrared Calibrator Repair

The Fluke 4181 (Hart Scientific) is a precision infrared calibrator — a large flat-plate temperature-controlled radiating target with an extended temperature range to calibrate infrared thermometers and thermal cameras. 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.

FlukeMeterRepair.com repairs and calibrates the Fluke 4181 for calibration labs and IR-thermometer service teams.

Common Fluke 4181 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.
• Stability faults — the target temperature not holding stable, the control loop corrected.
• Target-surface / emissivity faults — a degraded radiating surface skewing IR calibration, serviced.
• Display, interface, or power faults.

FAQs

My 4181 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.
