MAXOS® safety sight glasses have proved themselves universally where visual control of the process is essential, in pressure vessels subjected to additional thermal and chemical stresses.

The high safety level is secured by special borosilicate glass of high chemical durability, exceptional purity and homogeneity. Together with the low thermal expansion, which is typical for borosilicate glass, the thermal pre-stressing (tempering) creates a particularly high resistance to sudden temperature changes.

The characteristic values and small dimensional tolerances are guaranteed by multistage production and quality controls. With these exceptional safety characteristics MAXOS® safety light glasses can be used under extreme operational conditions. It is therefore mainly these safety aspects which influence responsible technicians again and again to choose MAXOS® sight glasses.

MAXOS® discs and long form sight glasses conform to the international specifications and standards.
