About us

       Testing and certification industry has been rapidly developed in Hong Kong over the past few years. However, the development of calibration field, which lays the foundations for testing and certification laboratories, had actually fallen behind the industry growth. Those laboratories in Hong Kong therefore need to seek calibration services that are offered in mainland Chain and even in overseas, which may lead to time-consuming process, high cost and increased risk of damage or loss during transport.
