DESCRIPTION

AQS series is micro air quality sensor used to monitor the current air quality around the installation point.

Compared with traditional standard air quality stations, it is smaller in size, lower in cost, and easier to install.

Its real-time air quality view helps governments and environmental management departments take action to protect public health, avoid the continuous spread of pollution, optimize infrastructure, and have more confidence in strategic planning.

It provides first-class accuracy, simple deployment, easy integration, long service life, and high reliability.

FEATURES

• Aluminium alloy with teflon coating
• Compact design
• No moving parts
• Easy to install and dismount
• Compatible to multiple outputs
• Low power consumption
• Maintenance-free
