Borosilicate sight glass DIN 7081Reflective and transparent borosilicate glasses DIN USAGE MAXOS® safety sight glasses are required everywhere where, under pressure, during thermal and chemical stress, the visual inspection of processes in containers must be ensured. High safety is achieved by a special borosilicate glass with good chemical resistance, extraordinary purity, and homogeneity. In conjunction with the typical low thermal expansion of this borosilicate glass, thermal pre-stressing (hardening) leads to particularly high thermal cycling resistance. Through production and quality checks in the process flow, the property values of the glasses and the tight tolerances are guaranteed. With these excellent safety features, MAXOS® safety sight glasses can be used under extreme conditions. 17092025 - Subject to technical changes and errors!

Borosilicate sight glass DIN 7081 Reflective and transparent borosilicate glasses REFLECTIVE AND TRANSPARENT GLASS Reflective glass: For dark media, dark or unlit containers, and a closed level gauge, it is advisable to use a reflective sight glass. (see adjacent image) The light refraction in the embedded prisms may provide a better visibility of the fill level. The liquid area is usually brighter than the area without liquid. If the color of the medium needs to be identifiable, transparent glasses should be used, as reflective glasses make a color change of the medium difficult to detect. However,...
