IAQ data logger for long-term measurements
For long-term monitoring of the indoor air quality: Use the IAQ data logger as a stand-alone measuring unit for carrying out long-term measurements with the testo 400 IAQ measuring instrument. While the stand-alone data logger is carrying out the IAQ measurement, you can use the IAQ measuring instrument for measurements elsewhere.
