Ideal for field or laboratory use, the Model 476-0 Single Pressure Digital Manometer measures low pressures from -20 to +20" w.c. with ±1.5% full scale accuracy. Designed especially for the HVAC contractor, the Model 476-0 can be used to set gas supply pressures, verify pressure switch operation, adjust regulators, check pneumatic systems and computer peripherals. The rugged, handheld unit is constructed with an extruded aluminum case for exceptional durability.

Pressure measurements can be quickly viewed on the large 4-1/2 digit LCD. The Model 476-0 Manometer features electronic zeroing to null out any minor pressure differences. Auto power off after five minutes conserves battery life.

The 476-0 Single Pressure Digital Manometer includes a quick start reference guide and a 9 V battery.
