Sight glass is a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within. They are made up of plastic or glass tubes which are connected to the bottom of the tank at one end and the top of the tank at the other. The level of liquid in the sight glass will be the same as the level of liquid in the tank. Certain sophisticated float switches have replaced sight glasses in many such applications.

Sight Glasses are used for viewing dry bulk materials in pneumatic convey lines. Sight glasses are invaluable for troubleshooting towers and checking instruments. They are used to check the function of electronic level transmitter.

Sight-float check valve is intended for use in vertical sampling applications and as a means of preventing vacuum scrubber contamination due to over-filling of the vertical sample leg or vessel before draining back into the sample container.

Sign Posts are lightweight, maintenance free and non-conductive. They are recommended for non road applications such as trailway signs in parks and directional/informational signs in buildings
