Fluke 7320 Calibration Bath Repair

The Fluke 7320 (Hart Scientific) is a precision calibration bath — it heats/cools and stirs a liquid bath across a moderate temperature range to calibrate temperature sensors with high uniformity and stability, including multiple probes. Its precision depends on the heater/cooling, the stirring system, the temperature control and reference, the insulation, and the fluid handling, which is where service focuses.

FlukeMeterRepair.com repairs and calibrates the Fluke 7320 for temperature-calibration labs.

Common Fluke 7320 problems we fix

• Fluid leaks — leaks in the bath vessel or fittings, repaired.
• Insulation degradation — poor stability or heat loss from degraded insulation, repaired.
• Heater / cooling / stirrer faults — won’t reach setpoint or stir evenly, repaired.
• Controller / reference drift — the controller or reference sensor reading the wrong setpoint, recalibrated against standards.
• Interface faults.

FAQs

My 7320 is leaking or won’t hold temperature — fixable? Yes. Leak, insulation, 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.
