TOUGHENED BOROSILICATE GLASS DIN 7080 - MAXOS®

MAXOS® Sight Glasses – DIN 7080

THERMISCH VORGESPANNTES BOROSILIKATGLAS DIN 7080 - MAXOS®pb
Safety Sight DIN7080 - MAXOS®

MAXOS® safety sight glass, specially hardened

Safety sight glasses are used wherever visual inspection of processes in vessels must be ensured under pressure, thermal and chemical stress.The high level of safety is achieved by a special borosilicate glass with good chemical resistance, exceptional purity and homogeneity. In conjunction with the low thermal expansion typical of this borosilicate glass, thermal tempering (hardening) results in particularly high thermal shock resistance.

KEEP TRACK OF THINGS

MAXOS® sight glasses are ideal as level indicators and for visual control of flows in pipes and containers. The extreme resistance of the glasses to temperatures and pressure loads guarantees fast and reliable monitoring of individual devices and systems.

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

  • as round DIN 7080 and
  •  level gauge glasses DIN7081.

The long sight glasses differ in two versions, reflex or transparent.

The reflex gauge sight glasses allow easy and safe observation even from a distance.
The transparent long sight glasses are used where particularly high requirements exist.

Further details like dimensions, temperature and chemical resistance for the MAXOS® sight glasses can be found in the catalogue as a download.
