AQS3000

Micro Air Quality Station

A miniaturized professional atmospheric composition station that monitors CO, SO₂, NO₂, O₃, PM2.5, PM10 and other atmospheric components. RGB breathing lighting intuitively reflects air quality, and a modular digital sensor design makes replacement and maintenance straightforward.

SO₂ / NO₂ / O₃ / COPM2.5 / PM10 / TSPRGB breathing light

The AQS3000 is a micro air-quality station with an exquisite design. It adopts the modular, digital and solid-state design concept for its sensors, making various configurations and disassembly easy. Six key air-quality parameters are monitored: electro-chemical sensors handle SO₂, NO₂, CO and O₃, while an optical particle counter delivers PM2.5 and PM10 — together pairing reference-grade meteorology with continuous gas and particulate readings.

AQS3000 can be widely used in smart-city networks, road weather, agriculture, forestry and plant protection. An RGB breathing light intuitively reflects the current air quality, and the optimized air duct makes sampling more sensitive and accurate.
