Gauge Glass for Heavy-Duty Level Indicators
Reflex Glass
Transparent Glass
Use this gauge glass with heavy duty level indicators.
Reflex glass shows the level of liquid behind it, but you won’t see the liquid’s color or the particulates in it.
Transparent glass helps you monitor the color of liquid and any particulates in it, in addition to the liquid’s level. Use two pieces of this glass in your indicator; the liquid flows between them, so you see straight through.
Use gaskets to seal the glass.
