Tempered high temperature borosilicate sight glass

Tempered high temperature borosilicate sight glass
The goods of high temperature resistant features, can be used for a long time under 450 degrees, instant temperature up to 500 DEGC, the tempering treatment, the anti shock function strong, low coefficient of thermal expansion is 3.25 x 10-6 K-1, high transparency. It is highly tolerant to water, alkali, acid and organic matter, and is lighter than sodium calcium glass. Compared with sodium calcium glass, borosilicate sight glass is lighter.
