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 lux kit, illuminance can be measured and documented efficiently. 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 measuring the illuminance in workplaces, for example in offices or in production areas. Keep the testo 440 air velocity and IAQ measuring instrument and a lux probe safely stowed away in the case. So you can get down to work straight away!
