Professional instrumentation calibration for industrial process plants
Accurate instrumentation is essential to the safe, reliable and efficient operation of any industrial facility. Milaco Engineering provides instrumentation calibration services to support planned maintenance, shutdowns, commissioning projects and routine calibration programmes across industrial environments.
As part of our expanding range of engineering services, we are developing our instrumentation capability to provide clients with a professional, dependable calibration service delivered by competent instrumentation engineers using traceable calibration equipment and recognised calibration procedures.
Whether supporting a planned outage, commissioning a new installation or carrying out routine maintenance, our objective is simple — to ensure your instrumentation is operating accurately before your plant returns to service. Our services can be tailored to suit planned shutdowns, commissioning activities or scheduled maintenance programmes, in both hazardous and non-hazardous environments where the appropriate competencies, procedures and permits are required.
How we work
Where our calibration support fits
Calibration and functional testing for a wide range of industrial process instrumentation.
Planned shutdown and outage support
Shutdown periods are the ideal opportunity to verify critical process instrumentation while equipment is safely isolated. We work with site engineering and maintenance teams to prioritise safety-critical and operationally important instruments.
Commissioning support
Correct calibration is an essential part of bringing new plant safely into operation. We verify instrument accuracy, confirm correct operation, and report defects or abnormal readings immediately so corrective action can be taken without delaying the programme.
Manual gauge calibration
Manual gauges remain an important part of many industrial processes and often require periodic verification. We provide manual gauge calibration with documented certification for maintenance systems, inspections and insurance requirements.

Calibration documentation and traceability
Good documentation is fundamental to an effective calibration programme. Milaco Engineering can work with client-specific calibration management software or provide our own structured calibration records where required.
- Instrument calibration records
- As-found and as-left readings
- Calibration certificates
- Manual gauge calibration certificates
- Instrument identification and traceability
- Defect reports and repair recommendations
Our aim is to provide clear, organised documentation that supports maintenance planning, auditing and regulatory compliance.
Professional engineering support
Instrumentation calibration is a specialist engineering discipline requiring the correct knowledge, procedures and equipment. Milaco Engineering is continuing to develop this capability as part of our wider industrial engineering services, providing clients with access to competent instrumentation engineers who understand the importance of accuracy, traceability and reliable process control.
Our focus is on delivering practical engineering solutions, clear communication and professional standards of workmanship on every project. Our instrumentation calibration services are suitable for a wide range of industrial sectors, including energy from waste, power generation, manufacturing, chemical processing, petrochemical, water and wastewater, and industrial processing facilities.
