Polished Reflex Gauge Glasses

Product Item：OV-0014

Standard: DIN7081

Material : Borosilicate glass 4.0

Type: reflex type gauge glass

Use:observe liquid level

Description

Polished reflex gauge glass is also name Polished Reflexion Gauge Glass which are made of specialized formular tempered borosilicate glass 4.0, distinguished by the grooves down the face. Polished flex gauge glass is no different from conventional reflex gauge glass in terms of technical parameters. The surface polishing treatment makes the glass more transparent to meet customers' differentiated needs.
There is 1,4 and 5 grooves on the glass for different market in the word.The grooves increase the angle of refraction which makes the visibility of the liquid level is much better than when using Transparent gauge glass. Mica is not suitable for Reflex Gauge Glass, and so without this protection they are not suitable for alkaline steam applications.
Reflex glasses may be used in pressure up to 35 bar at the max working temperature. In this area are sufficiently resistant to the environment. The reading is clear and contrasting. In the case of factors other than steam reflex glasses may be used up to 414 bar or 320˚C.
