Dwyer 475 Mark III portable manometer is a hand-held device for measuring low differential pressure. It is commonly used by engineers in the HVAC industry for balancing and commissioning clean rooms in hospitals and pharmaceutical sites. Dwyer 475 Mark III portable manometers measure differential pressures, with ranges starting at 0 to 0.249KPa. Push buttons on the front allow on/off, auto zero, and pressure unit selection. Extras are also available including a rubber boot with magnetic backing pads, a carry case and an air velocity kit with pitot tube for duct air flow measurement.
