Description

Fluke 1594A Super-Thermometer Repair

The Fluke 1594A (Hart Scientific) is a Super-Thermometer — a primary-lab-grade precision resistance thermometer readout that reads reference PRTs/SPRTs with extremely low uncertainty for the most demanding temperature calibration. Its precision lives in the ultra-precision resistance/measurement bridge, the probe inputs, and the internal reference, which is where service and calibration focus.

FlukeServiceCenter.com repairs and calibrates the Fluke 1594A for temperature-calibration labs, pharmaceutical QA, and metrology departments.

Common Fluke 1594A problems we fix

Measurement-bridge / reference drift — the resistance-bridge measurement out of spec, recalibrated against standards.
Probe-input faults — a channel not reading correctly, repaired.
Ratio / linearity faults — the measurement ratio out of spec, corrected and verified.
Display or interface faults — repaired.
Power-supply faults.

FAQs

My 1594A reads temperature wrong — fixable? Yes. Input, bridge, and reference faults are repairable, then it’s recalibrated so it reads to its full reference-grade accuracy, 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.
