AQ Guard Smart 1000 is a compact and cloud-enabled air quality measurement device. The system is designed for the requirements of outdoor air measurement in the smart city environment to improve granularity while maintaining high comparability to official measurements for environmental monitoring and health protection.

The system works on the principle of 90-degree scattered light measurement on the single particle, based on the EN 16450 certified Fidas® 200 technology. Signal duration and shape are taken into account.

The Fidas® technology used here also has decisive advantages over competitive products concerning long-term stability and function monitoring. In particular, the high size resolution of more than 200 channels enables a continuous check of the size deviation according to a patented procedure.

It provides additional information on the aerosol composition and origin, like no other device on the market.

AQ Guard Smart 1000 is suitable for outdoor use under extreme conditions. It has proven its performance under a wide range of meteorological conditions.

For better utilisation of its heat, the heated inlet is located inside the housing and is dynamically switched on depending on the humidity and temperature.

The AQ Guard Smart System has Ethernet, WLAN, and cellular connectivity and supports ASCII and MODBUS protocols for communication. All data is continuously recorded and can be retrieved retrospectively and in real-time.

The AQ Guard Smart 1000 supports model calculations of the current fine dust pollution and forecasts. These will be based on stricter limit values in the future, requiring lower uncertainties for local measurements.

The device offers manufacturers and users of low-resolution sensors a comparison option and, thus, a plausibility check before the measured values are made available for further processing in formation and dispersion studies.

Sensors that measure temperature, humidity, and pressure are integrated as standard.

AQ Guard Smart System has a pole or tripod mount and can be extended with a sunshade and LoRa modem if required.
