SCG Differential Pressure Gauge  for high accuracy--guaranteed within 2% of full scale--and for the wide choice of 81 models available to suit your needs precisely. Using SENCON's simple gauge,it quickly indicates low air or non-corrosive gas pressures--either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems. It's inexpensive, too. The  gage is the industry standard to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels with bubbler systems and pressures in fluid amplifier or fluidic systems. It also checks gas-air ratio controls and automatic valves, and monitors blood and respiratory pressures in medical care equipment. Note: May be used with Hydrogen. When ordering a Buna-N diaphragm pressures must be less than 35 psi.   Specification  SCG.zip Model Range(Pa) Model Range(In.w.c.) Model Range (Pa) Model Range (mm w.c.)
