Monitor and control the quality of indoor air to protect lives and build confidence.

In our changing world we are becoming increasingly aware of our immediate environment and its impact on our health. Indoor air pollutants have always posed a potential health risk and as it has now been acknowledged that Covid-19 can be transmitted through airborne droplets we need to understand exactly how clear the air is that we are breathing in to both protect ourselves and to feel safe indoors.

There are tangible and intangible impacts to being exposed to poor indoor air quality. Not only can it spread viruses, cause nose, ear and throat irritations, induce headaches and exaggerate asthma it can also be responsible for reducing our cognitive performance.

Air pollutants can cause damage through inhalation, digestion, and absorption through the skin and as most are colorless and odorless human detection is almost impossible. Having reliable monitoring of indoor air quality is key to help safeguard the health and wellbeing of the people in your care.

Aranet4 shows CO₂ measurements directly on its e-ink screen with a corresponding color indicator and configurable sound alarms.

The easy to use air quality monitor will improve your building’s operational performance and keep spaces safe. The Aranet4 provides the data necessary for you to stay in control and make well-informed choices. It will clearly display when the air quality in an indoor space is safe to reassure its occupants or alert you to take action to correct the environment.

Covid-19 can be spread by invisible respiratory droplets in the form of an aerosol that remain in the air for up to 9 minutes.

The survival of these airborne droplets depends on the quality of the air. Aranet4 accurately monitors C02 concentration, which is used as an indicator of air quality and whether there is sufficient ventilation. Should the quality of indoor air become unhealthy you will be alerted to take appropriate action and to increase the airflow to the room.

Proper ventilation significantly reduces the time these harmful aerosols remain airborne from 9 minutes to 30 seconds.
