testo 440 CO₂ Kit with Bluetooth®

  • Intuitive: clearly structured measurement menu for long-term measurement and parallel determination of CO₂ concentration, humidity and air temperature in indoor areas
  • Precise: absolute pressure compensation, calculation of wet bulb temperature, dew point and absolute humidity
  • 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
