Description
Fluke 721EX-1610 Pressure Calibrator Repair
The Fluke 721EX is an intrinsically safe dual-sensor pressure calibrator — a hazardous-area-rated version of the 721 that measures two pressure ranges (this 1610 variant covering a defined static/line range) plus the mA loop signal, for calibrating pressure instruments in Ex/hazardous environments. Its precision lives in the dual internal pressure sensors and the mA measurement circuit, with intrinsic-safety integrity that must be preserved through repair.
June Company repairs and calibrates the Fluke 721EX-1610 for oil & gas and hazardous-area instrument teams.
Common Fluke 721EX-1610 problems we fix
- Pressure-sensor drift — one or both internal sensors drifting out of spec, recalibrated against standards.
- Pressure-hold / leak faults — a leak that stops it holding applied pressure, repaired.
- mA measurement faults — the loop measurement, recalibrated.
- Over-pressure damage — sensor damage from an over-range event, assessed and repaired.
- Display or battery faults — serviced while preserving intrinsic-safety integrity.
FAQs
My 721EX-1610 reads pressure wrong — fixable? Yes. Sensor drift is repaired and recalibrated against our reference standards so both pressure ranges and the mA function are accurate, with a NIST-traceable certificate, and intrinsic-safety integrity preserved.
Are both sensors verified? Yes — each pressure range is checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
