Specifications (PDF)

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.

Also available is the convenient all-in-one kit (475-AV) is small, light and easy to use. No set-up or leveling needed. Included is a Pitot tube, two static pressure tips with magnetic mounting measure pressure drop across filters, condenser coils, etc. Kit comes complete with rubber tubing, 9V battery, step drill, AV calculator slide rule, and custom fitted carrying case. An indispensable test kit for the plant engineer, industrial hygienist and HVAC technician
