Dwyer Instruments 475-1-FM | Digital Manometer | 0-20 in w.c. | 10 psig max | Selectable English / Metric units
Between 1 in w.c. (0.249 kPa) to 150 psid (10.34 bar), the Series 475 Handheld Digital Manometer measures the positive, negative, or differential pressures of air and natural gases. The front panel's dual push pads manage the pressure unit selection, auto zero, and on/off functions, making setup unnecessary and enabling easy use. The Series 475 can also be used as an air velocity gage when coupled with a Dwyer® Pitot tube.
