W.C. range. The instrument indicates positive, negative and differential pressure with a frictionless magnet-driven helix and a silicone rubber diaphragm. It provides a 4 in. precision litho-printed dial, panel-mount bezel, IP67 enclosure rating, and overpressure relief for common HVAC, filter monitoring, duct pressure, blower and cleanroom applications.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e0-20 in.
