Instrument Service, Calibration & Support Across the UK

Technical expertise, practical support and experienced field engineers. Looking after your instruments throughout their working life.

Trusted by the UK’s Water and Energy Industry

From routine calibration and preventive maintenance to fault finding and repairs, our service team supports the instruments your site relies on. We bring together instrumentation knowledge, chemistry expertise and practical field experience.

At PMA, service is the foundation of everything we do. Our award-winning team brings technical expertise and practical support to the instrumentation we supply.

Whether you manage a remote water treatment site or a high-pressure energy facility, our engineers support you with commissioning, calibration, troubleshooting, optimisation and repair.

Support covers online water quality and process measurements, including pH, turbidity, nitrate, phosphate, ammonia and dissolved oxygen. Our engineers help investigate drift, fouling, reagent dosing and data integration issues, with findings explained to your team.

Why PMA Service Is Unmatched

People, chemistry and instrumentation expertise, brought together to keep your site running.

Instrumentation and chemistry

Our engineers understand both your instruments and the chemistry behind them. From phosphate monitors and UV-VIS sensors to nitrate analysers, they diagnose faults, fine-tune systems and optimise performance.

Clear, responsive support

Patient, practical support for operators on site and project engineers working remotely. We explain the issue, the work carried out and the next steps, keeping your team informed.

Engineers across the UK

Field engineers strategically positioned across England, Scotland and Wales bring technical expertise to your site, including remote water treatment locations and demanding energy facilities.

Beyond the hardware

PMA manufactures and supplies reagents and calibration solutions for online analysers. Our engineers understand how reagents interact with your process, helping troubleshoot the analyser and its application.

Planned visits and repairs

Routine calibration, preventive maintenance and reactive breakdown support help keep instrumentation performing. Visits are documented, parameters checked and findings explained to your team.

Service informed by data

Where available, we review trends, diagnostics and data logs for early signs of drift, fouling and inefficiency. Fine adjustments can extend instrument life, reduce chemical use and support consistent compliance.
