Indoor Air Quality CO2 Monitor Aranet4 PRO TDSPC003

Note: To use Aranet4 PRO, you need the (Reciver) base station with the reference: TDSBWPA1.XXX. There is the Aranet 4 PRO version that does not need the base station please see

Covid-19 can be spread by aerosols that remain in the air for up to 9 minutes. Propoer ventilation can reduce the risk of Covid-19 infection. CO2 concentration can be used as an air quality indicator and can be monitored with sensors such as Aranet 4 PRO. 

Aranet 4 PRO warns when the air quality has become unhealthy and you should take care of the airflow in the room.

Key Features:

• Checks for Carbon Dioxide (CO₂) concentrations
• Maintenance free NDIR (non-dispersive infrared) CO₂ sensor
• Indoor Air Quality displayed in ppm with Good (0 to 1000ppm), Average (1000 to 1400ppm), unhealthy (>1400ppm) indication
• User programmable Visible and Audible CO₂ warning alarm:
• CO₂
  • Range: 0 to 9999 ppm
  • Resolution: 1 ppm
  • Accuracy (2): ±50 ppm or 3% of reading (3)
• Temperature
  • Range: 0 to 50°C
  • Resolution: 0,1°C (0,1°F)
  • Accuracy: ±0,3°C (±0,5°F)
• Relative Humidity
  • Range: 0 até 85% hr
  • Resolution: 1%
  • Accuracy: 3%
• Atmospheric pressure
  • Range: 0.3 to 1.1 atm (4.4 to 16.0 psi)
  • Resolution: 1 hPa
  • Accuracy: ±1 hPa
• Long term drift:
  • CO₂: N/A (4)
  • Temperature: 0.03°C/ ano (0.05°F/ year)
  • Relative humidity: 0,5%/ year
• Line of Sight Range: 3 km (1.9 mi)
• Transmitter power 14 dBm
• Supported ISM bands: EU868, NA915
• Data transmission interval (6): 1, 2, 5 ou 10 minutos
• Data protection: XXTEA encryption
• Compatible base stations: Aranet PRO
• Ingress Protection cod: IP20

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. Due to regulatory requirements 1 minute data transmission interval is not available in Russia.
7. Weight with alkaline AA Fujitsu LR6G07 Premium batteries.

You can only improve what you can measure!

Take care of the air you breathe with Aranet4 PRO. It is the first step towards healthier environment around you, your loved ones, friends and colleagues.

The monitor shows on the display the current CO₂ content of the room air, the temperature, humidity and the time.

The LED's illumination colour (Green, Wellow and Red) can be used to quickly evaluate and interpret the current CO2 readings. Alternatively, can be used an alarm signal in the event when a certain limit has been exceeded. 

The importance of air quality for humans

The CO₂ concentration in indoor areas is deemed to be an essential indicator of suitable air quality. Carbon dioxide is a gas that is poisonous for humans and, depending on the concentration in the air, affects their performance, their well-being and their ability to concentrate. Even when there is a CO₂ concentration as low as 1,000 ppm, most people feel the air is not good and the above-mentioned disorders occur.

Optimal Locations for CO₂ Transmitters

• Avoid locations where people may breathe directly onto the sensor. Also avoid placing sensors close to intake or exhaust ducts, or near windows and doorways.
• In demand controlled ventilation wall-mounted sensors provide more accurate data on ventilation effectiveness than duct-mounted sensors. Duct-mounted sensors are best suited to single-zone systems and should be installed as close to the occupied space as possible to allow for easy maintenance access.
• When measuring CO₂ for the purposes of personnel safety, transmitters should be installed close to potential leakage points to enable early detection. The geometry, ventilation, and airflow of the monitored area need to be taken into account. The number and location of the CO₂ transmitters should be based on a risk assessment.
