Fluke 7380 Calibration Bath Repair
The Fluke 7380 (Hart Scientific) is a high-temperature calibration bath — it heats and stirs a liquid bath to high, uniform, stable temperatures to calibrate temperature sensors, including multiple probes. Its precision depends on the heater, the stirring system, the temperature control and reference, and the fluid handling, which is where service focuses.
FlukeMeterRepair.com repairs and calibrates the Fluke 7380 for temperature-calibration labs.
Common Fluke 7380 problems we fix
- Heating-element replacement — won’t reach the high setpoint, the heater replaced.
- Stirrer-mechanism rebuild — poor uniformity from a failing stirrer, rebuilt.
- Controller / reference drift — the controller or reference sensor reading the wrong setpoint, recalibrated against standards.
- Stability or uniformity out of spec — control-loop faults, corrected.
- Leak or interface faults.
FAQs
My 7380 won’t reach high temperature or stir evenly — fixable? Yes. Heater, stirrer, and controller faults are repairable, then the bath is recalibrated so temperature is accurate, stable, and uniform, with a NIST-traceable certificate.
Is uniformity verified? Yes — stability and uniformity are checked against our reference standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
