Fluke 5128A Humidity Generator Repair

Description

Fluke 5128A Humidity Generator Repair

The Fluke 5128A (RHapid-Cal) is a portable humidity generator — a benchtop standard that produces stable, accurate relative-humidity and temperature conditions in a test chamber to calibrate humidity probes and instruments. Its accuracy depends on the humidity-generation system, the temperature control, and the reference sensors, which is where service and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke 5128A for calibration labs and environmental-monitoring teams.

Common Fluke 5128A problems we fix

• Saturated-salt / desiccant contamination — contaminated humidity-generation media or paths cleaned and serviced.
• Humidity-generation faults — won’t reach or hold the setpoint humidity, repaired.
• Temperature-control or reference-sensor drift — recalibrated against standards.
• Chamber / seal faults — leaks preventing stable conditions, repaired.
• Display or control faults.

FAQs

My 5128A won’t hold humidity — fixable? Yes. Generation and control faults are repairable, then it’s recalibrated so chamber humidity and temperature are accurate, with a NIST-traceable certificate.

Are humidity and temperature verified? Yes — checked against our standards.

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