Dwyer Instruments 475-2-FM-AV
HH Digital Manometer w/Air Velocity Kit,0-40"H2O
The Series 475 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 V 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 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" ID vinyl or rubber tubing. Complete instructions are conveniently printed on rear of housing.
