Our factory mainly produces glass measurement instruments of over 200 sorts varieties and over 1800 varieties. Through many years’ research and test, our project technicians eliminated the traditional “etching” technique over many years and merged “carving” and “printing” into a body by the theory of rouge flambe diffusing and pigmenting, and created firstly series products of “carving and printing titrimetric pipe”. It wins the national paten (named ZL 92 1 02552 1) and the products have the following characteristics:

1. With the clear lines, marked reading and strong alkali resistance, it can’t change the color for a long time, guarantees the strength of itself, promotes the work efficiency and lightens the labor intensity.
2. For the alkali resistance test, the products is dipped into potassium dichromate solution for 24 hours and boiled in 1.0m NaoH solution for 10 hours. The dividing line and measuring value is intact and nondestructive.
3. The capacity is accurate. According to the detection for many times by Henan Provincial Measurement Test Research Institute, all technical targets are meet the international standard of GB12805-91 and is welcome by broad customers since it is put into markets.

　　In 1996, it was awarded the titles of “enterprise up to the standard of quality management” by Agriculture Ministry of P.R.CHINA, and “famous product of Henan Township Enterprise” by Henan province. From 1992 to 2001, it was granted the “trusted quality” and “trusted measurement” enterprise by Zhengzhou City Technological Supervision Bureau year after year. Our products filled many blank spaces for Henan provincial glassware and are praised by the provincial and municipal leaders.
