Borosilicate Reflex Gauge Glass

The reflex gauge glass is made from borosilicate glass, with low coefficient of thermal expansion, good thermal stability and chemical performance.

The side facing the medium chamber is provided with moulded grooves set at 90° angles. The moulding process increases the resistance of the glass groves to wear; the ‘’skin‘’ which the glass attains during moulding gives it maximum smoothness and hardness.

This makes it extremely resistant to the attack of boiler water.

The quality of gauge glass depends on its chemical composition, mechanical strength, dimensional accuracy.

Bending strength is determined by the surface compressive stress and the inherent resistance of the glass. The inherent resistance is heavily dependent upon the

surface quality.
