FAQ
Do you ship worldwide?
No, we are an authorized partner in these countries – UAE, Kuwait, Oman, Bahrain, Saudi Arabia, Qatar.
How does Aranet Home app enhance the use of Aranet Home sensor?
Aranet Home app allows you to view 90-day historical data, helping you notice and analyze patterns in radiation levels. It also enables you to adjust device settings, including measurement intervals and alarm thresholds, for personalized monitoring.
What are the recommendations for indoor air humidity?
Indoor humidity levels should range from 30% to 50%. This range supports comfort, health, and helps prevent the growth of mold.
How to export measurement data from Aranet Home App?
Simply go into your Aranet Home App, and tap onto the dashboard view in the top right corner. Once there, tap on the “Sharing” icon in the top right corner and choose how you would like to share or download it.
Can I find my lost Aranet4 sensor via app?
Aranet4 sensor must be within Bluetooth range to change settings within the app. If the sensor is within Bluetooth range, you can try changing the warning thresholds to custom settings (e.g., 300 ppm for yellow; 400 ppm for red, so it beeps if it is lost somewhere with fresh air). Alternate the buzzer between ‘Off’ and ‘On Every Time’ to create beeps.
How do I change the threshold at which Aranet4 buzzes?
If switched on, the buzzer emits a sound when the CO2 concentration reaches the red threshold, which is set by default to 1400 ppm. To change it, follow these steps:
1) Open your Aranet4 app;
2) Click on the ‘Gear’ icon in the top right corner;
3) Select ‘Warning thresholds’ under ‘Advanced’;
4) Choose ‘Custom’ and change the thresholds as desired.How to set a buzzer on Aranet4 HOME?
To set up a buzzer, follow these steps:
1) Open your Aranet4 App;
2) Click on the “Gear” icon in the top right corner;
3) Select ‘Buzzer’ and choose ‘On, once’ or ‘On, every time’ depending on your preference.How can I extend the warranty on my Aranet Home products?
You can extend the warranty of your Aranet Home products by an additional 12 months by registering the product and agreeing to receive email updates from SAF Tehnika. You can withdraw your consent to receive emails anytime without affecting the extended warranty.
How and when to calibrate Aranet4 HOME?
Aranet4 is calibrated at the factory, so if you’ve just received your new device, there is no need to calibrate it immediately. We recommend calibrating Aranet4 once a year.
Aranet4 can be calibrated either automatically or manually at home. In automatic calibration mode, the Aranet4 device needs to be exposed to fresh air with approximately 420 ppm of CO2 (for example, outdoors or in a room with very good air exchange) for about 8 hours during each 30-day operation period.
For manual calibration, the Aranet4 device must be exposed to fresh air (around 420 ppm of CO2), such as in a forest. The environment should be stable (unchanging) for 30 minutes during the calibration. Maintain a distance of at least 1 meter from the device during the calibration process to ensure the CO2 from your breath doesn’t affect the calibration. To initiate manual CO2 calibration, change the 1st switch position at the back of the device, behind the batteries, from MANUAL to AUTO and back to MANUAL, keeping a maximum of 1 second between each movement. The batteries must be installed in the device. The calibration progress will be displayed on the device’s screen.
For a reference background CO2 level, please check a global outdoor CO2 level map. Manual calibration can also be performed using Aranet Home app. Instructions for manual calibration via the app are available in the Aranet4 Calibration Tutorial.
Why do I need to monitor CO2 concentration?
High CO2 levels can negatively affect your well-being, comfort, and productivity. For example, if CO2 levels reach 1000 ppm, your cognitive abilities drop by 15%. At 1400 ppm and above, they decrease by a staggering 50%. Additionally, CO2 monitoring helps to prevent the spread of COVID-19, as CO2 level is a good proxy for airborne infection risk.
What is the NDIR sensor and why is it preferred over other types of sensors?
Aranet4 uses a non-dispersive infrared (NDIR) sensor to measure CO2 levels. The device features a small gas chamber with an infrared light source, where CO2 absorbs the light. An optical filter in front of the detector then filters out all light except the wavelength absorbable by CO2 molecules, enabling a precise CO2 concentration level measurement. This CO2 reading method offers higher precision than regular electro-chemical sensors, as it uniquely detects carbon dioxide with no interference from other gases. Furthermore, the NDIR sensor has a much longer lifespan and requires less recalibration than other sensors.
