Dwyer 477AV-00 | Digital Manometer | 0-4.00" w.c., Air Velocity/Flow
Ranged 0-4.00 in w.c. with a 5 psig maximum pressure, the Dwyer 477AV-00 handheld manometer calculates air velocity and flow internally, cutting the time and errors of working them out by hand. Readings from the 477AV-00 can be shown in 12 pressure, 7 velocity and 3 flow units.
- Rated to 5 psig over a 0-4.00 in w.c. span
- Zero and span can be set in the field
- Flow units: cfm, m3/h, m3/s
- Accuracy ±0.5% of full scale between 15.6 and 25.6°C
- 4-digit 0.42" LCD; runs on a 9 V battery
- Damping function for unsteady readings
