SAF Aranet4 Home: Wireless Indoor Air Quality Monitor for Office or School (CO2, Temperature, Humidity and More) Portable, Battery Powered, E-Ink Screen, App for Configuration & Data History

Product Information

It provides a much better budget option than the Vitalight Mini CO2 Monitor, and it’s a device that makes CO2 monitoring that much more accessible. This indoor air quality monitor features a CO2 sensor alongside PM10, tVOC, relative humidity, and temperature sensors. Over time, carbon dioxide sensors begin to drift, and if left unchecked, they will provide inaccurate readings over the weeks, months and years we use them. That said, I expect carbon dioxide monitors to record similar measurements at lower concentrations, as their accuracy is highest at these low concentrations. Since the product itself only has one button, this is where you will be changing all settings associated with the monitor.

It monitors the current CO2 concentration in the classroom and clearly signals with coloured lights when ventilation may be needed. With that said, even with more findings constantly coming to light, we already know that monitoring carbon dioxide is critical.On the Qingping+ App (the app which you’ll want to download to get the most out of the monitor), you can view historical data and change the measurement units of the device. I appreciate the inclusion of this mounting hardware, as it makes any of these monitors perfect for office or classroom use. The nail file was perfectly described, however only gave 4 stars as the listing says 'in aluminium case' and mine is in an 'eco storage case' (i. A great opportunity to expand your CO2 monitoring network or explore the benefits the ARANET solution provides.

Since CO 2 is a good proxy for COVID-19 infection risk, monitoring carbon dioxide and proper ventilation can help mitigate the spread of this and other airborne diseases. As carbon dioxide concentrations increase, the accuracy of sensors begins to decrease, and we expect to see a more pronounced difference. Further leaning into this carbon dioxide monitor’s simplicity is its lack of a companion app or connectivity.

Secondly, and more importantly, the device has an auto-calibration feature, which can render the device inaccurate if you don’t know how to account for this ‘feature’.
