Conbraco Industries 20-305-00 Square Water Gauge W/12" X 5/8" OD Glass Rod 1/2" MNPT

The Conbraco Industries 20-305-00 Square Water Gauge is a high accuracy instrument that is used to measure water pressure in HVAC systems. With a 12” x 5/8” OD glass rod and a 1/2” MNPT connection, this gauge is made of bronze to provide long-lasting, accurate readings. It works by the basic concept of hydrostatic pressure and offers differential readings for the levels of water. This water gauge is traditionally installed on chilled water systems and air-handling units and is used to gauge flow and pressure, which optimizes system work rates.
