Red Reflex Gauge Glasses With One Groove

Red Reflex Gauge Glasses With One Groove

Product Item：OV-001

Standard: DIN7081

Material : Borosilicate glass 4.1

Type: Reflex gauge glass

Use:observe liquid level

Description

Red Reflex gauge glasses DIN 7081 are also name Reflexion Gauge Glass which are made of specialized formular tempered borosilicate glass 3.3, distinguished by the grooves down the face.
There is 1,4 and 5 grooves for different market.The grooves increase the angle of refraction which makes the visibility of the liquid level is much better than when using Transparent Plain glass. Mica are not suitable for Reflex Gauge Glass, and so without this protection they are not suitable for steam applications.

Reflex glasses may be used in pressure up to 35 bar. 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 400 bar or 400˚C.
