Readings should be accurate out of the box as it is factory calibrated! If not, you can manually calibrate it and begin getting accurate readings within a few hours. I’m not sure what the box looks like, but if it doesn’t cover the vents on the device, it should still function as normal.
This is far from cheap, and the pricing might seem very steep for a device that monitors only CO2. Unfortunately, this is one of the biggest issues with CO2 monitors – they have a steep barrier to entry regarding the price.While there are cheaper options, many will still cost you over 100 USD. With NDIR only recently entering the consumer market, prices for this technology are expensive and likely will be for a while to come. Like - Looks good; compared to two other co2 monitors - appears accurate; love the extra features via the app; bluetooth; is portable - can take it with me everywhere; is tiny for handbag size.
I work as a secondary school teacher and use my Aranet4 every day to monitor and manage classroom air quality. If I was the Minister for Education there would be one installed in every classroom, staff room and office. Until then for any teacher interested in breathing clean air in their workplace, and protecting their students an Aranet4 is certainly worth the investment. This blog is a handshake with the Aranet4 HOME: an instrument specialized in measuring key indicators of overall air quality.

The built quality of the device is excellent, even if the whole product is plastic. The accuracy is best in class, the battery life is fantastic, and the app worked flawlessly throughout my time with the device.Is the school that your children attend monitoring IAQ? Air conditioned class rooms are now the norm, what fresh air input levels are used? Does your child suffer from tiredness, fatigue after a day at school? Managing the air quality of the class room is an important factor for today’s educators. Do you have any thoughts or experiences with Aranet4? If so, please feel free to share in the comments below! Alternatively, if you have any questions about the device, please ask, and I will do my best to answer. Thanks for reading! Carbon dioxide is a prevalent gas, and it’s something that surrounds us. However, while we hear about the impacts of carbon dioxide in the atmosphere almost every week, we rarely hear about the microscale impacts of carbon dioxide. Considering we live in an atmosphere including carbon dioxide, surely it can’t harm us? The stand out feature of this device is its ability to show all its measurements on screen. Using tech similar to the Eve Room, the display employs an e-ink screen which provides an informative, if a little small, panel of readings.
Recently, carbon dioxide monitors have been gaining a lot of attention. With findings showing how detrimental CO2 is to our cognitive performance and drowsiness levels, it’s no wonder that more people are interested in monitoring the carbon dioxide concentrations in their local environment. Power-efficient e-ink display ensures super long battery life for this wireless device (up to 5 years) When it comes to CO2 monitors, NDIR sensors are the gold standard. NDIR stands for nondispersive infrared. These sensors shine light through an air-filled tube inside the device, and a sensor on the other end of the tube measures how much IR light reaches the sensor. The difference in light emitted by the lamp and that which reaches the optical sensor on the other end of the tube indicates how much light is absorbed by CO2 and, therefore, how high the CO2 concentration is.

Of course, the time will come when you need to recalibrate your Aranet4 Home. To do this, you will want to take your device outside (somewhere with a carbon dioxide concentration as close to 420 ppm as possible) and leave your device alone for about 30 minutes. You will then want to walk a few metres away (so your breath doesn’t interfere with the ambient levels) and press ‘start calibration’ on the app. The perfect companion for indoor environments, allowing you to monitor CO2 levels, temperature, relative humidity, and atmospheric pressure in real-time Aranet4 uses non-dispersive infrared (NDIR) sensor for measuring the CO₂ level. The device has a small gas chamber with infrared light source in which CO₂ absorbs the light. An optical filter in front of a detector then filters all of the light except the wavelength that the CO₂ molecules can absorb so a precise measurement of the CO₂ level can be made. For this reason, automatic calibration should only be used if you regularly take the device outside. Aranet Tech Support suggests the minimum should be eight hours every month, which doesn’t need to be done simultaneously. As long as the cumulative time the Aranet4 spends exposed to outdoor air is eight hours monthly, automatic calibration should be reliable. Some features can be controlled from the app while other are only accessible via dip switched that are under the cells in the battery compartment.
