Description
Fluke 9133 Infrared Calibrator Repair
The Fluke 9133 (Hart Scientific) is a portable infrared calibrator — a compact flat-plate radiating target (emitter) with an extended range that presents a known surface temperature in the field to calibrate infrared thermometers. Its precision depends on the temperature-controlled radiating target (emitter), the temperature control and reference sensor, and the surface emissivity, which is where service and calibration focus.
FlukeServiceCenter.com repairs and calibrates the Fluke 9133 for thermal-imaging professionals, calibration labs, and predictive-maintenance teams.
Common Fluke 9133 problems we fix
- Emitter-surface reconditioning — a degraded radiating surface skewing IR calibration, reconditioned.
- Temperature-controller recalibration — the controller or reference sensor reading wrong, recalibrated against standards.
- Heating-system faults — won’t reach the setpoint, the heater repaired.
- Stability faults — the target temperature not holding stable, the control loop corrected.
- Display, interface, or power faults.
FAQs
My 9133 target temperature is off — fixable? Yes. Emitter, heating, and control 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.
