Calibration and Service

Calibration is the alignment, adjustment and fine tuning of a system or instrument so that it fulfills its function accurately and reliably. GMS Instruments not only stocks an enormous assortment of measuring and regulating equipment but also provides calibration and service to get your equipment working at the right levels. Often it is about the fine tuning of a scale, the size adjustment of certain materials and/or checking whether an apparatus has a deviation. Besides this, GMS Instruments provides you with a comprehensive test, service and repair facility to get your equipment to the desired level and keep it there. GMS Instruments is specially accredited and trained for gas detection equipment. Many ship owners put their personal safety in our hands with contracts for annual service and calibration of their gas detection instruments. Because we all feel that life matters.
