Mass flow meter repair, electronic and mechanical: gas mass flow and pressure instruments get board-level micro-soldering, ultrasonic cleaning, and recalibration after every repair.

## Healthy first, calibrated second

A calibration is only worth something on a healthy instrument. A mass flow meter with a damaged sensor will still produce a reading — it can even be nudged through a calibration — but it will not hold that calibration; it drifts. So before we calibrate anything, we make sure the device itself is sound: sensors, valves, electronics, battery, seals.

For devices that support it, we back up the on-board memory before touching anything — settings and calibration data included — so there is always a known-good state to return to.

## Which flow instruments do we repair?

Electronic and mechanical faults alike: sensor and valve problems, damaged fittings, display and interface failures, contaminated flow paths.

### Our own instrument line

The instruments we know deepest — board-level repair, adjustment and calibration, with the factory behind us when a unit needs to go deeper.

### Aalborg instruments

As the official Aalborg European Service Center.

### SKC air sampling pumps

A dedicated service line at our SKC service center.

## Board-level electronics repair

Electronic faults get repaired at component level, not board-swapped away. The bench is built for it: a trinocular microscope over the work, proper soldering and hot-air stations beside it, and a technician who has seen the inside of these instruments for years.

Component-level work keeps repair costs proportionate — and it keeps instruments alive that a board swap would have written off.

## Mechanical repair

Valves, seals, fittings, pump mechanics — mechanical wear is half of what walks through the door. We strip, clean, re-seal and rebuild, with genuine parts where a partner brand is involved.

## Ultrasonic cleaning

Flow paths pick up what flows through them. Where a flow path or an assembly needs deep cleaning, it goes into an ultrasonic bath — under a laboratory fume hood, with chemistry chosen for the contamination and the materials at hand, not a one-size-fits-all dip.

## Repaired, then proven

No repaired instrument leaves on trust. After the repair it goes through the same verification and — where the device calls for it — the same calibration as any instrument sent in for calibration alone, and the certificate shows what was found and what was left.

## How to send in your device

Diagnosis first, quote before any work — that part never changes. The practical side is one procedure for every device we service.

## Instrument not behaving?

Describe the fault and our engineers will tell you whether repair is worthwhile — usually the same day.
