Testo 440 CO₂ Kit with Bluetooth

The Testo 440 CO₂ Kit with Bluetooth is a practical solution for assessing indoor air quality in workplaces and other occupied environments. Supplied with the Testo 440 air velocity and IAQ measuring instrument and a Bluetooth CO₂ probe with integrated temperature and humidity sensors, it is well suited to facility managers, HVAC engineers and indoor climate specialists who need reliable CO₂ monitoring alongside wider IAQ checks.

A key strength of the kit is its ability to measure several important indoor climate parameters together. The Testo 440 offers a clearly structured menu for long-term measurement and parallel determination of CO₂ concentration, humidity and air temperature, while also automatically calculating values such as dew point, wet bulb temperature and absolute humidity with absolute pressure compensation. This makes it a strong choice for users who need more than a simple spot-reading CO₂ meter.

The Bluetooth connection helps reduce cable clutter and gives greater freedom during on-site checks, with a wireless range of up to 20 m. The kit also supports efficient documentation, with storage for up to 7,500 readings and USB export as CSV files for analysis and reporting. Supplied in a basic case, it offers a professional and expandable setup for indoor air quality measurement.
