With the testo 440 CO₂ kit with Bluetooth®, all IAQ-related parameters for evaluating indoor air can be measured and documented wirelessly. 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.
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.
Kit for evaluating the indoor air quality. The testo 440 air velocity and IAQ measuring instrument and the CO2 probe with Bluetooth® including temperature and humidity sensor are all safely stowed away in the case. So you can get down to work straight away!
