Testo 440 ComboKit air quality measurement kit allows you to make all the relevant measurements to assess indoor air quality and to determine the risk of sinking and the degree of turbulence in workplaces.
Testo 440 ComboKit for air quality measurement includes:
- Intuitive: Clearly structured menus for long-term measurement and parallel determination of CO concentration, humidity, air temperature and degree of turbulence in workplaces
- Accurate: Calculation of wet bulb temperature, dew point and absolute humidity – Determination of degree of turbulence and risk of sinking in accordance with EN ISO 7730 / ASHRAE 55
- Convenient: Wireless probe, internal data storage and USB connection for data export
- Versatile: The air velocity and HVAC instrument can be extended with a large range of digital probes (optional)
