Designated unit for national standards of measuring instruments.

The original Tianjin Glass Instrument Factory was the earliest state-owned enterprise in the glass industry in Tianjin. Since our company's transformation in 1999, we have continued to deepen the reform and innovate in the existing technological processes, as well as in the workmanship and technology of various production equipment. We have drafted and participated in the revision of national standards and routine glass measuring instrument calibration procedures.
