The Series 475 Mark III can also be used as an air velocity gage when used with a Dwyer ® Pitot tube.
The Series 475-FM Mark III is housed in a sturdy extruded aluminum case with a solid-state circuit board placed on a rigid fiberglass epoxy circuit board. To order to satisfy the most demanding requirements and maintain instrument reading accuracy, the 1″ w.c. the range is optimized for position sensitivity by means of a special dual sensor system. The standard 9-volt battery provides up to 100 hours of service. Two push pads on the front panel monitor on-off, auto-zero, and pressure meter selection. No configuration or leveling. The wide 0.42″ LCD display is easy to read. Units have a “small power” indicator.
