Dwyer Instruments 475-8-FM | Handheld digital manometer | Range 0-150.0 psi (10.34 bar) | Max. Pressure 200 psig
From 1 in w.c. (0.249 kPa) to 150 psid (10.34 bar), the Dwyer 475 portable digital manometer monitors the positive, negative, or differential pressures of air and natural gases. The on/off, auto-zero, and pressure unit selection are all controlled by the twin push pads on the front panel, making operation straightforward and requiring no setup. The Series 475 can also be used as an air velocity gauge when paired with a Dwyer Pitot tube. According to FM approval, this product is fundamentally safe in Class 1, Div 2, Groups A, B, C, D, and T4 Ta = 70°C hazardous areas.
