Product Details

Reflex Sight Glass

Reflex level gauge glass is made from High Borosilicate, AluminosilicateThey are used in level gauge in boiler for water position. Reflex type one side facing the medium chamber is provided with molded grooves set at 90 degree angles. 
The molding process increases the resistance of the glass grooves to wear; the skin which the glass attains during molding gives it maximum smoothness and hardness.
This makes it extremely resistant to the attack of boiler water 

Transparent Gauge Glass

Transparent type is also manufactured from “extra-hard” borosilicate glass. The surfaces on both sides are finely smooth and ensure optimal transparency.
A) One is as same with reflex Gauge Glasses,use molds to make the semi-finished products,afterwards,ground and polish the two side to ensure optimal transparency. By this manufacturing technique,the definition isn’t good.

B)The other manufacturing technique is made of High Borosilicate sheet of 17mm thickness, cut the glass sheet according the detailed size and polish the side face for the smooth.
This manufacturing technique glass is very clear,but the goods cost is higher.
