Convenient all-in-one kit is small, light and easy to use. No set-up or leveling needed. Digital manometer reads from 0-20" w.c. with ±0.5% F.S. accuracy. The Series 477AV stores up to 40 readings in memory for later reference, with selectable English/Metric pressure, flow and velocity units that are visible on a large, backlit 0.4" LCD readout. Both audible and visual overpressure alarms and a “low battery” warning are standard features.
