The Retrotec DM32 WiFi is a dual channel touchscreen(wireless option) manometer/differential pressure gauge for blower door and duct leakage systems, such as the Retrotec 450 DucTester. It is small, lightweight and exceptionally intuitive to use.
The DM32 WiFi can be controlled with a computer (MS Windows only) or any Android or iOS smart device. DM32 WiFi can be connected via WiFi, Ethernet, or USB. Ethernet cables of 100 m / 328 ft segments can be used, offering an unlimited distance of reliable control, without the need for pressure tube extensions.
Included with the DM32 WiFi is a package of analytical software, developed exclusively for the DM32 WiFi, to equip testers with the most comprehensive tools available to collect, export, and evaluate air leakage testing results.
New DM32 WiFi features developed in the future can be updated easily onto the gauge from the internet.
