Indoor air quality probe for CO2, temperature, humidity and absolute pressure

0632 1535
  • 4 functions in one probe: measurement of CO2, humidity, temperature and absolute pressure
  • Rapid checking of the indoor climate
  • Prevention of poor air quality in indoor rooms via CO2 measurement
  • Product no longer available. Have you checked out its successor?
    Why not enjoy the benefits that it has to offer:
    >> To the product (fixed cable)
    >> To the product (wireless, with Bluetooth)
    Please note that the successor products are only compatible with testo 400 or testo 440.
    Use the probe to quickly check the indoor climate, for example in offices, production areas or in warehouses. As well as temperature, humidity and absolute pressure, it also measures the carbon dioxide concentration (CO2).

    The CO2 concentration is a primary indicator of indoor air quality. Poor air quality due to excessive concentrations of CO2 can cause tiredness, lack of concentration and even illness. Therefore the CO2 concentration should normally not exceed 1000 ppm.
