Product & Solution
- Disc sight glasses
- Long form reflex and transparent

MAXOS® safety sight and level gauge glasses have proved themselves universally where visual process control is essential. This includes pressure vessels subjected to thermal and chemical stresses and liquid level gauge application. A high safety level is secured through the use of special borosilicate glass of high
chemical durability, exceptional purity and homogeneity. The low thermal expansion of our SUPRAX® 8488 borosilicate glass, combined with thermal prestressing (tempering) creates a high resistance to sudden temperature changes. The material properties values and small dimensional tolerances are guaranteed by production and quality controls. With these exceptional safety characteristics, MAXOS® safety sight and level gauge 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®
