Borosilicate Gauge & Sight Glasses
The gauge glass is the most important component of the liquid level gauge.
The quality of a sight (gauge) glass depends mainly on the chemical composition and mechanical strength of the glass material.
Constant glass quality is provided through glass analyses and acid/alkali tests. The mechanical strength is attained through thermal pre-stressing.
KLINGER gauge glasses are suitable for installation in liquid level gauges of almost any make.
Exclusively made of “extra-hard” borosilicate glass which is subsequently heat-treated.
KLINGER gauge glasses have high mechanical strength and are exceptionally resistant to alkalis, acids and boiler water (within the service limitation). KLINGER’s glass testing laboratory carries out continuous quality control tests for purity of glass, flaws in glass, dimensional accuracy, etc.
This ensures the high quality standard of all KLINGER gauge glasses. KLINGER reflex and transparent glasses are manufactured according to the most varied international standards.
