AEMC CA 1510 [2138.08] Indoor Air Quality Monitor/Data Logger, Gray. Indoor air quality has become a significant public health concern in recent years. Numerous studies have shown that environmental factors in the office, classroom, and home can have a significant impact on physical comfort and mental performance. The Indoor Air Quality Logger 1510 helps address this issue by monitoring temperature, humidity, and carbon dioxide (CO2) in the local environment. This compact, easy-to-use instrument provides quick and accurate readings, and can store up to a million measurements. Monitoring CO2 levels in these environments can be highly beneficial. In addition to the potential health effects caused by breathing high concentrations of this gas, CO2 level also serves as a good indicator of the efficiency of the building’s air ventilation and circulation system. Free Android app: You can also work with the 1510 from an AndroidTM mobile device by downloading a free app from the Google Play Store. This app from Chauvin Arnoux enables you to connect to the instrument, view measurement data (in tabular or graphical format), start and stop a recording session, download recorded data, configure the instrument, and perform other tasks.
