Borosilicate Transparent Gauge Glass
The transparent gauge glass is also manufactured from ‘’extra-hard’’ borosilicate glass, with low coefficient of thermal expansion, good thermal stability and chemical performance.
The surfaces on both sides are finely ground and polished to ensure optimal transparency.
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.
Technical characteristics
Working temperature : 400°C
Pressure: Max 6Mpa
Bending strength: standard level gauge glasses ≥120Mpa
Chemical resistance
Alkali resistance: alkali class 2, tested to DIN ISO695

Acid resistance: acid class 1, tested to DIN ISO1776/DIN12116.
Packing
The glass is packed in individual white box, cardboard case.
Application
Widely used for observation of vessels (tanks/boilers/industrial oven/liquid level gauge), chemical processing, water engineering, oil refineries and marine engineering etc.
