Accredited Testing & Calibration

GT Instrument  Sdn Bhd was initially involved with the supply/sales of test equipment & specialized machinery and  after sales technical support that includes commissioning, services , maintenance and calibration.  As part of our continual improvement and value added services to the industries, in year 2000, we embarked on getting our calibration services accredited to ISO 17025.  We have since expanded our accredited calibration services and our current scope of is as listed below. [Download: Scope of Accreditation]

To further enhance our services to the industries, we have added testing as our new ISO 17025 accredited services. Our accredited testing services includes mechanical test for rubber, plastics and composite materials.
