The Dwyer® Series 475
Mark III Handheld Digital Manometer 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.
The meter's simple
operation and easy to read digital display make it an indispensable
test instrument for the plant engineer, industrial hygienist and
HVAC technician. When used with a Dwyer® Pitot tube, the Series 475
Mark III can also be used as an air velocity gage.
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" w.c. range is compensated for position
sensitivity through use of a unique patented dual sensor
system.
A standard 9 volt
battery provides up to 100 hours of operation. Dual push pads on
the front panel control on-off, auto zero, and pressure unit
selection. No setup 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.
