Dwyer DM-1000 DigiMag Digital Differential Pressure Gauge
Product Introduction
The Dwyer DM-1000 DigiMag® Digital Differential Pressure Gauge is a
versatile, precision instrument designed to monitor pressure for
air and compatible gases. Building on the legacy of the renowned
Magnehelic® analog gauge, this digital model offers enhanced
functionality with factory-calibrated ranges and a 4-digit LCD
display that shows readings in both standard and metric
units—eliminating the need for manual conversions. With simplified
four-button operation, including digital push-button zero and span,
it streamlines setup and calibration. The gauge can be
field-programmed to measure pressure, air velocity, or flow
(depending on the model), making it ideal for diverse industrial
applications. A standout feature for filter systems allows users to
set a threshold, triggering a blinking display when a filter needs
maintenance, ensuring proactive upkeep.
