Fluke 700G31 Pressure Calibrator Repair

Description

Fluke 700G31 Pressure Gauge Calibrator Repair

The Fluke 700G31 is a precision pressure gauge calibrator — a reference pressure gauge (700G series, high-range) that measures pressure with high accuracy for calibrating and checking pressure instruments, often paired with a pump for source-and-measure work. Its precision lives in the internal reference pressure sensor and the measurement circuit, which is where service and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke 700G31 for process and instrument-calibration technicians.

Common Fluke 700G31 problems we fix

• Pump rebuild — a worn pump (where used as a source-and-measure set) that won’t build or hold pressure, rebuilt.
• Pressure-sensor recalibration — the reference sensor drifting out of spec, recalibrated against standards.
• Pneumatic seal replacement — leaks at seals/fittings that stop it holding pressure, repaired.
• Over-pressure damage — sensor damage from an over-range event, assessed and repaired.
• Display or battery faults.

FAQs

My 700G31 reads pressure wrong — fixable? Yes. Sensor and seal faults are repairable and recalibrated against our reference standards so it reads accurately across its range, with a NIST-traceable certificate.

Is the full range verified? Yes — checked against our standards.

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