The Aranet4 Range

No matter what your needs are, there is a CO2 monitor out there that is perfect for you. By monitoring the CO2 levels in your indoor spaces, you can help to improve the air quality and ensure a healthy environment for yourself and others.

The use of CO2 monitoring devices like the Aranet4 have become increasingly popular as people are starting to take air quality quite seriously. Since the covid-19 pandemic there has been a surge in looking for ways to reduce the spread of viruses and create healthier environments.

We’re often asked by customers what the difference is between the Aranet4 Home and Aranet4 PRO and which one they should get, that’s why we’ve decided to take this opportunity to highlight the differences between them and help you decide which one suits your needs best.

What do the Aranet4 sensors do?

The Aranet4 sensor is a battery powered, wireless Bluetooth device that monitors CO2 levels.

With a clear, easily visible e-ink display and a straightforward traffic light system that indicates when CO2 levels have become unhealthy, the monitors are easy to use and allow you to react quickly to improve the air quality when needed.
