IAQ Probe - IAQ Probe

Order-Nr.  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

Designed to be used in applications that require multiple measurements, the IAQ simultaneously monitors CO2, relative humidity and temperature. The IAQ Probe has a MiniDIN connection.

Product Description

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.
