Fluke 1595A Super-Thermometer Repair
The Fluke 1595A (Hart Scientific) is a Super-Thermometer — the highest-accuracy precision resistance thermometer readout, reading reference SPRTs with the lowest uncertainty for primary temperature metrology. 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 1595A for temperature-calibration labs, pharmaceutical QA, and metrology departments.
Common Fluke 1595A problems we fix
- Probe-input / reference faults — a channel not reading correctly or the reference drifting, recalibrated against standards.
- Measurement-bridge faults — the resistance bridge out of spec, repaired.
- Ratio / linearity faults — the measurement ratio out of spec, corrected and verified.
- Display or interface faults — repaired.
- Power-supply faults.
FAQs
My 1595A 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.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
