Digital Differential Pressure Gauge
The Dwyer Instruments DM-1208 is a digital differential pressure gauge designed for HVAC technicians and facility engineers who need to measure low-pressure air and gas systems. It provides a 0 to 10 in WC range with +/-1% accuracy on a 4-digit LCD. The unit operates on a 9V battery or 9 to 24VDC supply and carries CE agency compliance.
Suited for air velocity and flow checks
This gauge suits professionals verifying duct static pressure, filter loading, or air velocity in ventilation systems. It displays readings in in H2O, FPM, m/s, CFM, or cubic meters per hour. Buyers who require a permanently mounted transmitter with analogue output or data-logging capability should look at a different instrument class.
0 to 10 in WC measurement range
The single specification that decides fit is the 0 to 10 in WC range with +/-1% accuracy. If the application demands measurement outside this span or tighter tolerance, the DM-1208 will not meet the requirement. The 1/8 inch smooth barb connection and back-mounted case complete the installation profile.

Questions about this item
Should I pick the 0.125 model or a different range for my application?
This DM-1208 measures 0 to 10 in WC with ±1 % accuracy, so choose it when your pressures fall inside that span.
What does the 0 to 10 in WC range mean when I connect the gauge?
It reads differential pressure up to 10 in WC and also converts to air velocity in FPM or m/s and flow in CFM or m³/h.
How does the 1/8" smooth barb connection limit what I can hook up?
The back-mounted barb accepts 1/8" O.D. tubing; pressure above 10 in WC or incompatible fittings will exceed the gauge’s limits.
