Sight Glass
Application:
Sight glass widely used in all types of hermetic pump to observe the condition inside the container. Our sight glass is manufactured through high temperature sintering process. Thus, it has good air impermeability, high pressure withstanding capacity, and clear surface that ease the process of observation. Besides, we provide custom made service to our customer to manufacture sight glass that has extra high pressure withstanding ability with clear vision.

Surface treatment:
We adopt the environmental friendly electroplating technique, which is electroless nickel plating at 3-5 μm thickness. The nickel coat does not contain hazardous substances such as mercury, lead, cadmium and hexavalent chromium, reaching EU's standards. It passed the SGS environmental test.
- Corrosive resistant ability: After a 12 hours 5% salt spray test, the rusty area must not exceed 5% of the total area according to the ISO9227-2017 test standard.
- Salt spray test standard: GB/T2423.17,IEC60068-2-11,ISO4628-3
