Fluke 1620A Thermo-Hygrometer Repair

Description

Fluke 1620A Thermo-Hygrometer (DewK) Repair

The Fluke 1620A (DewK) is a precision thermo-hygrometer — a benchtop instrument that monitors and records temperature and relative humidity to high accuracy (with smart probes) for environmental monitoring in calibration labs and controlled spaces. Its accuracy depends on the smart-probe inputs, the measurement electronics, and the reference, which is where service and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke 1620A for environmental-monitoring teams, pharma QA, and calibration labs.

Common Fluke 1620A problems we fix

• Probe-input / smart-probe faults — a probe channel not reading correctly, repaired and recalibrated against standards.
• Temperature / humidity measurement drift — readings out of spec, recalibrated.
• A function dead — a measurement or logging path failed, repaired.
• Display, interface, or alarm faults — repaired.
• Power faults.

FAQs

My 1620A reads temperature or humidity wrong — fixable? Yes. Probe and measurement faults are repairable, then it’s recalibrated so readings are accurate, with a NIST-traceable certificate. (Send the matched smart probes if they’re part of the measurement.)

Are the readings 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.
