Flat Sight Glass – Cobalt Blue Borosilicate
The Inifu flat cobalt blue sight glass is specifically designed for flame observation due to its coloration. Made from borosilicate glass 3.3, known for its low thermal expansion coefficient, this material is internationally recognized as ideal for industrial sight glass applications. Its thermal stability allows usage at temperatures up to 500ºC and up to 550ºC for short periods, while its chemical stability ensures performance under severe corrosion conditions (see resistance tables).
This borosilicate 3.3 flat sight glass with cobalt blue filter is engineered to withstand extreme temperature and pressure in industrial environments. The borosilicate glass ensures excellent chemical resistance, and the cobalt blue filter acts as an optical aid, enhancing visibility in processes where clarity and precision are critical. It is ideal for flow monitoring and liquid level applications in industries such as petrochemicals and pharmaceuticals.
Flat Sight Glass – Features
Primarily used for flame observation in burners or boilers, flat sight glasses are also ideal for monitoring processes where the brightness emitted by the operation hinders clear visibility.
