REED R9905 Data Logging Indoor Air Quality Meter

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.
