Handheld Digital Manometer measures positive, negative and differential pressures. It is housed in rugged, extruded aluminum case. It is lightweight, fast and easy-to-use and is featured with selectable English/metric units. Also, it is FM approved. Our Glass Level Indicator is ideal for field calibration, monitoring or trouble shooting HVAC systems, clean rooms, or a wide range of other low pressure pneumatic systems. This handy instrument measures positive, negative or differential pressures of air and natural gases in ranges from 1 in. W.C. (0.249 kPa) to 150 PSID (10.34 bar). The Series 475-FM is approved and is intrinsically safe for hazardous locations, Class 1, Div. 1, Group A, B, C, D, T4. It’s simple operation and easy-to-read digital display makes it an indispensable test instrument for the plant engineer, industrial hygienist and HVAC technician. When used with a Dwyer® Pitot tube (see Flow and Air Velocity), the Series 475-FM Mark III can also be used as an air velocity gage. See the complete 475-1-FM-AV kit described below.

The Series 475-FM Mark III is housed in a durable extruded aluminum case with its solid state circuitry mounted on a tough fiberglass epoxy circuit board. To meet the most demanding applications and to provide stability of instrument reading, the 1 in. w.c. range is compensated for position sensitivity through the use of a unique patented dual sensor system. A standard 9 volt battery provides up to 100 hours of operation. It has dual push pads on the front panel control on-off, auto zero and pressure unit selection. No set-up or leveling. The large 0.42 LCD display is easy to read, minimizing data collection errors. Units include a “low battery” indicator. The pressure sensor used is a highly stable silicon piezoresistive device. Standard connections are dual sized for 1/8" or 3/16" I.D. vinyl or rubber tubing. Complete instructions are conveniently printed on rear of housing.


475-AV Air Velocity Kit : Includes the Series 475-FM Manometer, two A-303 static pressure tips two 9 ft. lengths 3/16 I.D. rubber tubing, no. 166-6- CF Pitot tube, A-397 step drill, A-532 air velocity slide chart and instruction bulletin H-11, all packed in a tough, molded plastic carrying case with die cut foam liner. To order, add AV suffix to any standard 475 model no.


A-402A Carrying Case : Tough gray nylon pouch protects any Series 475 Manometer. Double zippered for quick and easy access. With belt loop that snaps closed.
