CO2 probe incl. temperature and humidity sensor, fixed cable

Use the CO2 probe with the compatible Testo 440 multifunction measuring instrument (sold separately) to determine CO2 concentration, air humidity and air temperature. Wet bulb temperature, dew point and absolute humidity are calculated at the same time. This probe can be used to check the indoor climate areas such as offices, production areas or storage facilities. To ensure accurate measurement results, air density compensation is carried out via the integrated absolute pressure measurement. The readings of the CO2 probe are transmitted to your measuring instrument using a connection cable. You can store individual readings directly in the Testo 440 measuring instrument by pressing the button on the probe. The clearly structured measurement menus for long-term measurement enable the measuring instrument to be operated intuitively. Reading trends are reliably recorded thanks to the convenient input of measurement time and measuring cycle. You can use these trends to evaluate changes in the indoor air quality.
• Intuitive: clearly structured measurement menus for multiple applications
• Precise: calculations are performed automatically inside the Testo 440 application screens
• Convenient: Universal connection handle can be easily combined with other probe heads
• Intelligent calibration concept. Only the probe tip needs to be sent for calibration.
