These gauges are used to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid level with bubbler systems. Can be flush or surface mounted. Requires 4-9/16" hole for flush, panel mount. Also available as a pressure switch/gauge.
