Description
The Aranet4 HOME is a wireless CO₂ monitor for home and work that measures air quality in real time. Thanks to a true NDIR sensor (non-dispersive infrared) — the same measuring technology used in lab equipment — the device delivers accurate CO₂ readings in ppm, complemented by temperature, relative humidity and atmospheric pressure.
Ideal for bedrooms, home offices and classrooms: the Aranet4 HOME helps you recognize insufficient ventilation and rising CO₂ levels in good time, both during the day and at night.
The E-Ink display ensures low power consumption and a battery life of up to 4 years — giving you long-term, maintenance-free monitoring with no subscription costs. The device syncs with the free Aranet Home app for trends, notifications and historical data.
Featured on TV
The Aranet4 HOME has been featured on television in Belgium (De Zevende Dag, with Marc Van Ranst) and in the Netherlands (Maurice de Hond).
Practical and easy to use
Thanks to the replaceable batteries, the device is easy to take anywhere or mount. The display clearly shows the measured value, and a green/orange/red indicator immediately warns when the CO₂ level becomes too high. The measurement data is recorded automatically, without you having to configure anything yourself.
