Kit for carrying out measurements in ventilation ducts and at air outlets: The testo 440 air velocity and IAQ measuring instrument, the vane probe (Ø100mm) with Bluetooth including temperature sensor, and the vane probe (Ø16mm) are all safely stowed away in the case. So you can get down to work straight away!
● Intuitive: structured measurement menu for volume flow and determination of air velocity, humidity, and temperature in ventilation ducts or at ventilation outlets.
● Clever: vane probe (Ø16mm) with a telescope (0.85m) - combine the vane probe (Ø100mm) with Bluetooth with the telescope for ceiling outlets or the funnel set for plate outlets (please order separately) as required.
● Convenient: wireless probe, internal data storage, and USB port for data export.
● As multifaceted as your challenges themselves: the testo 440 can be expanded with a large portfolio of digital probes.
TESTO 440 - AIR VELOCITY AND IAQ MEASURING INSTRUMENT
Use the testo 440 air velocity and IAQ measuring instrument in combination with high-quality 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 a type K thermocouple connector. Automatic probe detection and structured measurement menus guarantee simple operation and will make your day-to-day work easier.

VANE PROBE WITH BLUETOOTH INCLUDING TEMPERATURE SENSOR
Use the vane probe with the compatible testo multifunction measuring instrument (please order separately) to measure air velocity, volume flow and temperatures up to +70 °C. The readings of the vane probe are transmitted to your measuring instrument via Bluetooth, up to a distance of 20 m. The clearly structured measurement menu for volume flow enables the measuring instrument to be operated intuitively. The volume flow is precisely calculated thanks to convenient input of the size and geometry of the duct cross-section. Timed and multi-point mean calculation, average volume flow, current reading and min./max. values are displayed in the measuring instrument.

VANE PROBE (WIRED)
Use the vane probe with the compatible testo multifunction measuring instrument (please order separately) to determine air velocity and volume flow. Use the fixed cable to connect the vane probe to the measuring instrument. The probe is equipped with a telescope, which can be extended to a maximum length of 0.85 m. The immersion depth is easy to read off thanks to the scaling on the telescope.
