Why Metaglas® Is Considered the Safest Sight Glass in the World
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.
Metaglas was created to improve safety conditions within plants that handled corrosive chemicals, chemicals worked at high temperatures and those worked under high pressures. The safety concerns became serious enough that competing companies joined forces to create Metaglas.
