MAXOS® safety sight and level gauge glasses have earned global confidence in themselves, recognizing the indispensable necessity of visual process control worldwide. This encompasses pressure vessels subjected to rigorous testing, chemical resistance, and liquid level monitoring for heightened safety standards. The high safety level is assured through the utilization of special Borosilicate glass, renowned for its exceptional chemical resistance, purity, and consistency. The low thermal expansion of our SUPRAX® 8488 Borosilicate glass, coupled with thermal prestressing (tempering), creates robust resistance to rapid temperature fluctuations. Material property values and precise dimensional tolerances are guaranteed through meticulous production and quality controls. With these outstanding protective features, MAXOS® safety sight and level gauge glasses can operate under the most extreme conditions. Therefore, it’s the repeated demonstration of responsibility-driven technicians choosing MAXOS® due to its exceptional safety characteristics, further emphasizing the importance of this responsibility in selecting MAXOS®.
