Rectangular Sight Glass Manufacturers
A Rectangular Sight Glass industrial view sight glass is a window used to observe the level, colour, and clarity of liquids in industrial process equipment. Rectangular view sight glasses provide a comprehensive, unobstructed view of the process chamber, making them ideal for use in difficult-to-see areas.
They are often used in conjunction with level gauges to provide a more accurate reading of liquid levels. Rectangular view sight glasses are available in a variety of sizes and configurations to meet the needs of different industries and applications.
