Fluke 1621 Calibration

Description

Fluke 1621 Thermometer Calibration and Repair

The Fluke 1621 is a precision digital thermometer — it reads a connected reference temperature probe (PRT/thermistor) with high accuracy for temperature measurement and calibration work. Its accuracy lives in the probe input and the measurement reference, which is where service and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke 1621 for calibration labs and metrology teams.

Common Fluke 1621 problems we fix

• Probe-input / reference drift — the temperature reading out of spec, recalibrated against standards.
• Probe-connector faults — a damaged input connector giving erratic readings, repaired.
• A function dead — a measurement path failed, repaired.
• Display or interface faults — repaired.
• Power or battery faults.

FAQs

My 1621 reads temperature wrong — fixable? Yes. Input and reference faults are repairable, then the thermometer is recalibrated so it reads accurately, with a NIST-traceable certificate. (Send the matched probe if it’s part of the measurement.)

Is the reading verified? Yes — checked against our temperature standards.

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