1. The device measures absolute pressure, i.e., the readings are not compensated for an elevation above the sea level.
2. 95 % of the sensors measure within these typical limits in equilibrium state at the time of sale. For evaluation of the total measurement error long-term drift has to be taken into account.
3. CO2 measurement accuracy is provided for a range 400 … 2000 ppm, temperature 15 … 35 °C (59 … 95 °F) and relative humidity 0 … 60 %. Accuracy above 2000 ppm is 10 % of reading, but not guaranteed since it is extrapolated form the calibrated range.
4. If a drift of the CO2 measurements occurs, calibration option of the device should be used.
5. Time constant is determined at 1 m/s airflow.
6. Weight with alkaline AA Fujitsu LR6G07 Premium batteries.Aranet4 is not impact resistant!
Do not leave the device in direct sunlight!
