Color, clarity and consistency. These are just three characteristics that operators can monitor with a sight glass observation port when processing food or beverage products. A sight glass window can supply a visual means to ensure proper blending or mixing, accurate measurements and adherence to stringent quality standards.
Since it was developed in the 1970s, METAGLAS® has been known as the safest sight glass in the world. A number of chemical and manufacturing companies collaborated to create METAGLAS, and to establish the standard with which it complies and by which all other sight glass is measured, a standard now called DIN7079.
