Transparent & Flat Gauge Glass

Description

DIN 7081 Transparent gauge glass is also named flat gauge glasses and plain gauge glass. Its typical characteristic is two-sided polished and whole body tempered. Transparent gauge glass is made from specific borosilicate glass material types-commonly 4.0 borosilicate glass which results in products characterized by high mechanical strength and high resistance to alkalis, acids and condensates.
The thermal shock resistance of transparent gauge glass is as high as 230 ° C, which makes the transparent gauge glass as an safety observation window with sudden temperature change in the application environment still stable without fragmentation. Transparent gauge glass is an ideal part as level indicators and for visual control of flows in pipes, tanks, and containers.
Transparent gauge glass has higher pressure resistance characteristics than reflex gauge glass, and a mica shield can be installed on the flat inner surface to isolate the alkaline components in the fluid and prevent it from corrosion.
