This data logging Indoor Air Quality (IAQ) Meter has the ability to record samples on internal memory and keep track of registered readings with a time and date stamp. The R9905 features a Nondispersive Infrared (NDIR) CO2 sensor for stable, accurate readings and the option to track live measurements via software.

Measure indoor air quality with ease and accuracy using the R9905 data logging indoor air quality meter, featuring a triple LCD that simultaneously monitors carbon dioxide (CO2), temperature, and relative humidity.
The R9905 can calculate the time-weighted average (TWA) and short-term exposure limit (STEL). Get accurate and stable readings with the low-drift NDIR CO2 sensor and get notified when measured levels are high with the user-adjustable audible alarms.
Wondering where all this data will be logged? The R9905 can record up to 32,000 data points and allows you to keep track of them with the internal time and date stamp.
