The Retrotec DM32X Digital Manometer breaks new ground by offering touchscreen interface and optional wireless compatibility. The beautiful 3.2” color touchscreen gives simple, visual access to any number of available devices and test units. The DM32 manometer is the backbone of any blower door or duct testing system, providing the essential pressure and flow measurements. More than just pressure and flow, however, the DM32 also performs many industry standard calculations including Air flow per area (CFM/sq ft), Air changes per hour (ACH/h), and Equivalent Leakage Area (EqLA). While controlling the blower door or duct test system, the manometer can provide full “Set and Forget” functionality, maintaining target pressure throughout a test. Firmware is easily updated to the latest version through a simple connection to a PC, while the lithium ion batteries are charged through a common USB cable, providing up to 10 hours of use on a single charge.

For even greater flexibility, choose the optional Retrotec DM32 WiFi Digital Gauge (part number Retrotec DM32W / Retrotec DM321). The DM32 WiFi offers all the features of the regular DM32, but can also communicate wirelessly with a PC, tablet, or smartphone. Applications are available for iOS and Android that allow complete control of the gauge, from simple monitoring of pressure to fan speed. Leave the DM32 manometer to maintain pressure at the blower door, for instance, while you move about the building to diagnose zonal pressures. Or set up the DM32 in a combustion appliance zone then monitor pressure changes with your phone as you work to depressurize the area. No existing network is necessary; the DM32 can create a wireless network directly with your device. The DM32 WiFi gives flexibility previously not possible. It’s almost like having a second manometer.
