The testo 440 combines the benefits of a compact handheld device with intuitive measurement menus and a comprehensive selection of air velocity & IAQ probes. This
means you have all measuring tasks on air conditioning and ventilation systems reliably under control.
With the testo 440 hot wire kit, all IAQ-related parameters in ventilation ducts can be measured and documented. The testo 440 air velocity & IAQ measuring instrument recognizes 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.
Kit for carrying out measurements in ventilation ducts: the testo 440 air velocity and IAQ measuring instrument and the hot wire probe (Ø 9 mm) including temperature sensor are all safely stowed away in the case. So you can get down to work straight away!
