The 30% CO2 + RH/T Data Logger measures up to 30% (300,000ppm) carbon dioxide, temperature, and relative humidity levels in ambient air. It “wakes up”, take a reading, stores it in memory, and goes back to sleep until the next reading is required.

The Bio-Logger is not designed for real-time data acquisition. Instead, it logs CO2 + RH/T with a date and time stamp into for downloading later. The logging interval is programmable from 30 seconds to 10 days. Up to 60,000 data points with time stamps can be stored in built-in, non-volatile memory. This means that your data is not lost even if the batteries are completely discharged.

The logger uses a built-in, rechargeable Lithium Ion battery. Taking one reading every 30 minutes,it can log data for up to 3 months.
