Testo 440 Humidity Set with Bluetooth - 0563 4404

GST included.

    With the testo 440 humidity kit with Bluetooth®, all IAQ-related parameters in storerooms, workrooms and walk-in refrigerators 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.

    • Intuitive: Clearly structured measurement menus for long-term measurements and parallel determination of humidity and air temperature in storage, refrigerated, and in ventilation ducts
    • Precise: calculation of dew point, wet bulb temperature and absolute humidity
    • Convenient: Wireless probes, internal memory for data storage, and USB port for data export
    • Versatile: Your testo 440 setup can be expanded with a large selection of digital probes

    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 carrying out measurements in storage, refrigeration and work rooms, in ventilation ducts and also on refrigeration systems and heat pumps. Keep the testo 440 air velocity and IAQ measuring instrument and the humidity/temperature probe with Bluetooth® safely stowed away in the case. So you can get down to work straight away!
