testo 440 Indoor Comfort ComboKit with Bluetooth®

  • 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
