Intuitive: clearly structured measurement menu for long-term measurement and parallel determination of CO₂ concentration, humidity, air temperature and degree of turbulence in workplaces
Precise: calculation of wet bulb temperature, dew point and absolute humidity – determination of the degree of turbulence and draught risk according to EN ISO 7730 / ASHRAE 55
Convenient: wireless probe, internal data storage and USB port for data export
As multifaceted as your challenges themselves: the air velocity and IAQ measuring instrument can be expanded with a large portfolio of digital probes
Use this practical Indoor Comfort ComboKit to handle all relevant measurements in order to evaluate the indoor air quality in indoor areas and to determine the draught risk and degree of turbulence in workplaces. The testo 440 air velocity and IAQ measuring instrument, the CO2 probe with Bluetooth® including temperature and humidity sensor and the turbulence probe are all safely stowed away in the case. So you can get down to work straight away
