NB! Aranet4 is not impact resistant. Do not leave the device in the direct sunlight.
1. CO2 sensor of the device is calibrated at standard atmospheric pressure. CO2 readings are pressure compensated and comply with the specifications down to 750 hPa. If the device has to be used at high altitude for a prolonged period of time, manual calibration of the unit should be
performed for optimal performance. It is not intended to use the device higher than 4,000 m (13,000 ft) above the sea level.
2. The device measures absolute pressure, i.e., pressure readings are not compensated for an elevation above the sea level.
3. 95% of the sensors measure within these typical limits in equilibrium state at the time of sale. For evaluation of the total measurement error longterm drift has to be taken into account.
4. CO2 measurement accuracy is provided for a range 0 … 5000 ppm, temperature 15… 35 °C (59… 95 °F) and relative humidity 0… 80%. Accuracy above 5000 ppm is 10% of reading, but not guaranteed since it is extrapolated form the calibrated range.
5. If a drift of the CO2 measurements occurs, calibration feature of the device should be used. Auto calibration mode is utilizing ABC algorithm whereas
Manual calibration mode demands sensor to be exposed to fresh air.
6. Time constant is determined at 1 m/s airflow.
7. Available only for the PRO version of the product.
8. Weight with alkaline Fujitsu Premium LR6G07 AA batteries.
9. Fujitsu Premium LR6G07 AA batteries used for tests and calculations.
10. Energizer Ultimate Lithium L91 AA batteries used for tests and calculations.
11. With the Bluetooth connection disabled. Battery lifetime data has been obtained by mathematical extrapolation and is provided for descriptive
purposes only and is not intended to make or imply any guarantee or warranty..
