Dwyer 475-3-FM Manometer 200-inch WC Intrinsically Safe FM Approved
Dwyer 475-3-FM is an intrinsically safe FM approved digital manometer that measures negative, positive, and differential pressures of natural gases and air from 0 to 200.00in W.C. The Dwyer 475-3-FM also measures air velocity when used with a pitot tube (sold separately) Dwyer Pitot Tube. The Dwyer digital manometer 475-3 is ideal for field calibration, monitoring, or troubleshooting HVAC systems, clean rooms, or a wide range of other low-pressure pneumatic systems.
Key Features
- Max pressure: 30 psi (207 kPa)
- Range: 0 - 200.00" W.C. (49.82 kPa)
- Large, easy to read LCD and simple operation
- FM approved to be intrinsically safe in hazardous locations, Class 1, Div 2, Groups A, B, C, D, T4 Ta = 70°C
Overview
The Dwyer 475 digital manometer dual push pads on the front panel control the on/off, auto-zero, and pressure unit selection, allowing for simple operation with no setup needed. The 475-3 manometer is housed in a durable extruded aluminum case with its solid-state circuitry mounted on a tough fiberglass epoxy circuit board that will meet the most demanding applications. The Dwyer 475 manometer is powered by a 9V battery and automatically shuts off after 20 minutes to conserve battery life.
