Types of AEROlite® Gauge Glasses

Reflex Glass

Featuring moulded grooves on the medium side for increased wear resistance. Optimum solution for up to 35 bar saturated steam. Can be used with most media (except steam) up to 400 bar or 400°C.

Transparent Glass

Made from "extra-hard" borosilicate glass with polished surfaces. Required for steam service above 35 bar or high pH-value media. Must be protected by mica shields for contaminated or corrosive media.
