DUMICO supplies all kinds of sight and gauge glasses. We deliver from stock standard DIN sizes Sight and Level Gauge Glasses MAXOS (Auer) and associated gaskets. In addition to standard sizes, we provide many specific custom sight and level gauge glasses (according to DIN 7080/7081 standard), as well as other glass qualities like quartz glass, ceramic glass (see technical glass) or metal fused glass. We deliver mica for all sight and gauge glasses to protect the glass against corrosion. As a result, the life span of the glass is considerably lengthened, which prevents production stops and glass changes.
