河北荣兴玻璃仪器厂主要生产的透明玻璃管，水族温度计，海水比重计，可调温加热玻璃管用于医学器械，化学仪器，纺织，水族等多个行业。对于其他要求耐高温、高热稳定性、高化学稳定性、高介电性能的工业技术部门亦得到广泛的应用。下述三类本厂均具有相应的生产线。A:普通玻璃管； B:高硼硅玻璃管；C:石英玻璃管；The transparent glass tubes which our factory manufacture are used in medical instruments, chemical instruments, textile and aquarium industries. They are also widely used in other industrial technology departments which require high temperature-resistant, high thermal stability, high chemical stability and high dielectric property. We have the corresponding production line for the following three kinds of products.A. normal glass tube; B: borosilicate glass tube C: quartz glass tube海水比重计Sea water hydrometer浮于水面的海水比重计，海水比重、盐度、显示精确，使用简单，读数容易，透明度高。Floating on the sea water, the hydrometer is transparent, and is easy to use and reads easily with accurate numbers.温度计温度准确，包装精美，出口产品永不掉字。本产品的在制作过程中需要经过高温使玻璃表面熔化，让度数侵入玻璃里面，因此不会有掉字的现象出现。ThermometerAccurate temperature, refined package, To be exported and would not be faded.This kind of product requires melting the glass surface through heating on the manufacture process, inserting the degree. So they would not be faded.
