Dwyer DM-1000 DigiMag Digital Differential Pressure Gauge

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.
