Product Description
The Testo 440 CO2 Kit with Bluetooth is a professional engineering solution designed for structured evaluation of indoor air quality (IAQ). This hardware assembly combines the Testo 440 multi-function air velocity and IAQ master instrument with a wireless digital CO2 probe incorporating integrated temperature and humidity sensors. The system provides automated parallel determination of carbon dioxide concentration, relative humidity, and air temperature, featuring built-in absolute pressure compensation and internal data storage.
Industry Applications
- Commercial Building Automation: Multi-point indoor climate logging and ventilation performance audits across office buildings and public infrastructures.
- Educational and Institutional Facilities: Auditing air hygiene and CO2 occupancy boundaries in schools, universities, and conference rooms.
- Industrial and High-Tech Workspaces: Maintaining micro-climate profiles and health compliance in manufacturing and laboratory environments.
