Digital Differential Gauge 0.5 In WC

The Dwyer Instruments DM-1103 is a digital low-pressure gauge designed for technicians who need to measure small differential pressures in HVAC, laboratory or process applications. It offers a 0 to 0.5 In WC range with a four-digit LCD that can display several engineering units.

Glass-Filled Plastic Case and Back Connection

The gauge body and socket are moulded from glass-filled plastic in a light grey finish, providing chemical resistance and a lightweight feel for handheld or panel use. A 1/8-inch smooth barb on the rear accepts flexible tubing directly, so the instrument sits flat against a panel while the hoses run behind it.

Accuracy and Power Options Define Suitability

Stated accuracy is ±2 % of full scale, which determines whether the resolution meets a given test specification. The unit runs from a 9 V battery or an external 9 to 24 V DC supply, letting the buyer choose between portable and permanently powered installations.

Questions about this item

What pressure range does the 0.5 in WC gauge cover?

The gauge measures differential pressure from zero up to 0.5 inches of water column, with selectable display units including kPa, Pa, mBar, mm H2O, mm Hg and percent full scale.

What tubing fits the 1/8 inch smooth barb on the back?

The back-mounted connection accepts 1/8 inch O.D. smooth barb fittings, so push-on tubing with a matching inside diameter slides directly onto the glass-filled plastic socket.

How do you power the DM-1103 for bench use?

Insert a 9 V battery into the compartment or connect an external 9 to 24 V DC supply; the unit operates from either source without additional configuration.
