Dwyer DM-1000 Series Digital Differential Pressure Gauge

American DWYER DigiMag® series DM-1000 digital differential pressure flow meter monitors the differential pressure flow of air and non-combustible compatible gases. The function is the same as the Magnehelic® differential pressure gauge. All models are factory-set. Range. 4-digit LCD can display inch and Metric reading. 4 buttons simplify calibration and setting operations.

The DigiMag® Series DM-1000 Digital Differential Pressure Flow Meter is a multi-function differential pressure gauge that can be field-programmed to operate on pressure, air velocity or flow according to the order model. DigiMag® Series Digital Differential Pressure Gauges can be set to display when used in filters The value flashes, prompting maintenance personnel to perform filter cleaning maintenance when the filter is clogged. DM-1000 Depending on the model, use 4 buttons to set security level, engineering units, K factor (for pitot tubes and flow sensors), filter settings Set, read peak and valley process data, smooth process data, display update, zero-to-full calibration, etc.
