IAQ Logger

The IAQ Logger, when combined with the Telaire 7001 Handheld CO2 Monitor, records the three leading indicators of indoor air quality: (1) temperature, (2) relative humidity, and (3) carbon IAQ100dioxide. This IAQ solution is ideal for those applictions requiring long-temperature and CO2 on the Telair´s large, easy-to read display.
