Model 476-0 digital manometer measures positive and negative pressure from 20 to 20-in. w.c. with ±1.5% full-scale accuracy. Suitable for field or laboratory use, the manometer sets gas-supply pressures, adjusts regulators, verifies pressure-switch operation, and checks pneumatic systems and computer peripherals. The instrument features electronic zeroing to null out minor pressure differences, and a 5-min auto shutoff to conserve battery life.
