Borosilicate Sight Glass Boiler Tank Level Gauge Glass

Transparent level gauge glass Transparent level gauge glass are also manufactured from "extra-hard" borosilicate glass. The surfaces on both sides are finely smooth and ensure optimal transparency. Now we have two kinds manufacturing technique: 1.One is as same with reflex Gauge Glasses, use molds to make the semi-finished products, afterwards, ground and polish the two side to ensure optimal transparency. But by this manufacturing technique, the definition isn't good. 2.The other manufacturing technique is: At first, we manufacture 17mm thickness glass sheet, then cut the glass sheet according the detailed size and polish the side face for the smooth. This manufacturing technique glass is very clear, but the goods cost is higher. It can be used with al…
