Use the testo 440 dP air velocity and IAQ measuring instrument in combination with the high-quality, digital probes to measure and store all air velocity and IAQ parameters (please order probes separately). Up to 3 probes can be connected simultaneously: a Bluetooth probe, a wired probe and a temperature probe with type K thermocouple connector. Automatic probe detection and clearly structured measurement menus guarantee simple operation and will make your day-to-day work easier.
A differential pressure sensor is already integrated in the testo 440 dP. This makes it possible to carry out measurements on filters and fans, as well as Pitot tube and K-factor measurements (please order Pitot tube separately).
