DM2 - Digital Manometer

The DM-2 is a two channel digital micro-manometer.

Note: The DM2 is only compatible with Model 3000 Fans & older. If using a newer model fan (including the Model 5000, Model 6000, Model 300, & Model 400), refer to the DM-32 Digital Gauge.

Retrotec's DM2

The DM-2 is a two channel digital micro-manometer, or differential pressure gauge. It combines simple but comprehensive functionality, with intuitive controls and setup.

The DM-2 is a digital gauge that always displays the pressure on Channel A, but can display pressure measurements, calculated air flow, air changes per hour (ACH), or equivalent leakage area (EqLA) on Channel B depending on the Mode selected. The Digital Gauge Package provides all the nice to have items a first time tester will need with the DM-2.

The DM-2 can also present the measured results in a number of different units, which meet the professional standards of many different countries and testing protocols. To ensure accurate results, the DM-2 takes up to four pressure readings per second on each channel, and updates the information displayed on the screen every second.

Retrotec’s DM-2 puts the operator in command of virtually every parameter of interest to an air leakage tester. It represents a huge advance in building and envelope diagnostic instrumentation, accurately measuring airtightness for duct testing, building air leakage, and clean agent enclosure integrity testing.
