Digital Differential Pressure Gauge DM-1102

The Dwyer Instruments DM-1102 is a digital differential pressure gauge built for technicians who need to measure low-pressure differentials in HVAC, laboratory or industrial airflow systems. It provides selectable readouts across eight engineering units so the operator can match the display to the job specification without conversion tables.

Glass-Filled Plastic Case and Flexible Power

A light-grey glass-filled plastic enclosure protects the electronics while keeping the instrument light enough for handheld use or panel mounting. The gauge accepts a 9 V battery for portable work or 9 to 24 V DC line power for permanent installations, letting the same unit serve both field-service and fixed-monitoring roles.

Verify Range and Accuracy Before Ordering

Confirm that the 0.125 full-scale range covers the maximum differential pressure your application will produce. Check that the stated accuracy of +/- 1.00 percent meets the tolerance required by your test standard or commissioning procedure. Ensure the available display units include the one mandated by your documentation.
