Carry out long-term measurements of indoor air quality with this IAQ data logger. Once the user is done taking the IAQ measurement, they can read out, analyze, and document all the saved values with the 400. Use the compatible probes (sold separately) to measure the comfort level, turbulence, radiant heat, CO2, CO, illuminance, air flow velocity, humidity and temperature. The IAQ data logger connection options for up to six fixed cable probes at the same time.
Features
Particularly useful: Since the data logger acts independently of the measuring instrument during the measurement, you can use the IAQ measuring instrument to carry out measurements elsewhere in the meantime.
