The Retrotec DM32 Wi-Fi is a dual channel touchscreen(wireless option) manometer/differential pressure gauge for blower door systems. It is small, lightweight and exceptionally intuitive to use. This rental unit is not suggested for the 451 DucTesters.
The DM32 Wi-Fi can be controlled with a computer (MS Windows only) or any Android or iOS smart device. DM32 Wi-Fi can be connected via Wi-Fi, 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 Wi-Fi is a package of analytical software, developed exclusively for the DM32 Wi-Fi, to equip testers with the most comprehensive tools available to collect, export, and evaluate air leakage testing results.
New DM32 Wi-Fi features developed in the future can be updated easily onto the gauge from the internet.
