With the testo 440 flow ComboKit 1 with Bluetooth®, all IAQ-related parameters at air vents and in ducts can be measured and documented wirelessly. The testo 440 air velocity & IAQ measuring instrument recognises probes automatically, and its structured measurement menus simplify the adjustment of air conditioning and ventilation systems.

Up to 3 probes can be connected simultaneously to the measuring instrument: a Bluetooth® probe, a wired probe and a temperature probe with Type K thermocouple connector.

The multifunction measuring instrument stores up to a max. 7500 measurement protocols, which can be read via a USB port and further processed as a CSV file on your computer (e.g. with Excel). With the testo BLUETOOTH/IRDA printer (please order separately), you have the option of producing a report printout of the measurement data directly on site.

The versatile Bluetooth® handle allows the connection of many different wireless probe heads for all applications. In addition to this, the kit contains a vane probe head, a wired hot wire probe and a storage case.
