Calibration & Certification

Calibration & Certification

Regularly tested and calibrated instruments are essential to ensure that your equipment is functioning correctly.

Pressure, temperature and other factors are leading parameters in practically all workplaces and every industrial process. This is why pressure and temperature measurement instrumentation plays an essential part in monitoring and protecting processes and environments. It also ensures that equipment functions perfectly on time, every time. And it’s not just quality and process monitoring or indications for preventive maintenance that is at stake, but people’s lives as well. Regularly tested and calibrated instruments are essential to ensure that your equipment is functioning correctly. Many internationally recognised inspection organisations and manufacturers also require that critical measurements equipment be tested and calibrated at regular intervals.

GMS Instruments is a certified and official calibration partner of many manufacturers.


Depending on the degree of accuracy required and the precise nature of the test or calibration, our technical advisors will make the appropriate choice from our extensive range of test and calibration equipment. To test a pressure switch, for example, a hand pump with an analogue gauge is the most effective solution, while the calibration of a temperature sensor on which the quality of your product depends may require a highly-accurate temperature calibrator supported by digital-based processing of the measurement data. Tell us what your calibration challenge is, and we will do the rest.


GMS Instruments has a certification service to help you with the certification of your equipment. We have our own certification service laboratory where equipment can be traceably tested, calibrated and certificated. We also offer an instrument rental service to cope with all your calibration requirements, from replacing instruments that are at our certification service to assisting with high workload volumes and non-standard applications.

Our hire equipment comes complete with calibration certificates complying with national and international standards. The inspection of the GMS Instruments calibration service is annually fulfilled by NMi or NKO, which means that all certificates are internationally retraceable.
