Rectangular Sight Glass

Rectangular Sight Glass is a flat, transparent glass panel with a rectangular shape, designed for visual monitoring of processes, liquid levels, or material flow within industrial equipment such as tanks, pipelines, or reactors. Constructed from durable materials like borosilicate glass or tempered glass, it offers high resistance to thermal fluctuations, chemical corrosion, and mechanical stress, while providing clear, unobstructed visibility. Its rectangular form allows for easy integration into rectangular or square openings, making it widely used in chemical, pharmaceutical, food processing, and energy industries to ensure operational safety and process efficiency through direct visual observation.
