Data sheet
BOROSILICATE GLASS DIN 7081 MAXOS®
Safety Sight DIN7080 and Level Gauge Glasses 7081 - MAXOS®

MAXOS® safety sight glasses are required wherever visual inspection of processes in vessels must be ensured under pressure, thermal and chemical stress.

MAXOS® sight glasses are manufactured in two different standard versions:

The long sight glasses differ in two versions, reflex or transparent.
The reflective glasses allow easy and safe reading even from the greater distance. The transparent long sight glasses are used where particularly high requirements prevail.

Further information such as dimensions, temperature and chemical resistance for the MAXOS® sight glasses can be found in the catalog as a download, or on our homepage under materials.

Long sight glasses are also available from us complete in long sight glass fittings.
