Reflex Gauge Glass Used In Boiler

Reflex gauge glass, also called reflex sight glass, reflex level gauge glass, boiler glass and reflex level gauge. The material of reflex sight glass is usually borosilicate glass and aluminosilicate glass. Our reflex gauge glass is polishing and tough. Reflex gauge glass has high mechanical strength and high resistance to alkali and acid characteristics. Another important factor of the boiler glass is transparency.

Reflex gauge glass is used to read the liquid level directly by eyes or industrial television. With the grooves, the reflex gauge glass has a few grooves which can make the level clearer and easier to be read.

A piece of clear reflex gauge glass with four grooves is on the ground.

Reflex gauge glass is used to read the liquid level of the boiler or instruments and the grooves can make the liquid level clearer.

Two piece of clear reflex gauge glass of about 280 mm and 140 mm length.

Our usually length of the reflex gauge glass is from 70 mm to 400 mm, and can be customized according to requirements.

A piece of thick reflex gauge glass with fine edge and clear surface.

The thick reflex gauge glass is suitable in aggressive environment, such as acid, alkali, high temperature and high pressure.

Features and Advantages

Acid and alkali resistance.
Borosilicate glass and aluminosilicate glass can resist acid and alkali, so that the gauge glass can work in aggressive environment. Reflex gauge glass is widely used in industry, where stable chemical property is an essential factor.
Customize form and dimension.
We have standard dimension in stock and we also accept customizing, which can meet most of your requirements.
Reflex gauge glass is suitable for reading directly or by industry television.
Reflex gauge glass is imprinted with a few longitudinal grooves, which increases the angle of refraction and can make it easier to read the liquid level. This makes it easier to read directly as well as by industry TV.
No strip, bubble, scrap or crack.

Two pieces of reflex gauge glass and a piece of transparent gauge glass are together.

The contrast of reflex gauge glass and without groove gauge glass is shown and the grooves make the liquid level clearer.

Application

The reflex gauge glass is used in various equipment, especially the liquid level needed to be read by industry television.

Industry boiler.
Some instruments.

A piece of clear reflex gauge glass is installed in a part of the boiler.

Reflex gauge glass is widely used in industry boiler to control the level of the water.

There is a set of industry boiler with a reflex gauge glass to see the water level.

Industry boiler is widely used in industry and reflex gauge is necessary to observe the liquid level.

Package and Transportation

In order to avoid breaking, reflex gauge glass is packaged in 5 layer corrugated cartons or pallet, with foam or bubble wrap.
We can also pack the reflex gauge glass according to customers' requirements.

An array of tubular gauge glass is vertically placed on the desk.
