AQT420空气质量监测系统是芬兰维萨拉公司研发的一款高性能环境监测设备，采用一体化紧凑设计，可同时测量多种关键空气污染物及气象参数。该系统能够精准监测二氧化氮（NO2）、二氧化硫（SO2）、一氧化碳（CO）、臭氧（O3）等气态污染物，并可选配PM2.5和PM10颗粒物监测模块。设备内置高精度电化学传感器，结合智能算法自动补偿环境条件和传感器老化带来的影响，无需额外气体采样设备即可实现ppb级测量精度。系统还集成了温度、湿度、气压等气象参数监测功能，为用户提供全面的环境数据支持。轻量化设计（1.25kg）和小型化体积（128×185×128mm）使其特别适合大规模空气质量监测网络部署。支持RS232/RS485本地连接和Modbus协议，同时提供开放API接口，便于系统集成和数据共享。典型应用场景包括城市空气质量网格化监测、工业排放监测、道路及隧道环境监控等。设备维护周期为12-24个月，运行功耗仅0.5W，体现高效节能特点。1256
AQT420 Air Quality Monitoring System Product Introduction (English)
The AQT420 air quality monitoring system, developed by Finland s Vaisala, is a high-performance environmental monitoring device featuring integrated compact design. It simultaneously measures multiple key air pollutants and meteorological parameters with precision. The system accurately monitors gaseous pollutants including nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and ozone (O3), with optional modules for particulate matter (PM2.5 and PM10) monitoring. Equipped with high-precision electrochemical sensors and proprietary intelligent algorithms, it automatically compensates for environmental variations and sensor aging effects, achieving ppb-level measurement accuracy without requiring additional gas sampling equipment. The system also incorporates weather monitoring capabilities for temperature, humidity, and atmospheric pressure, providing comprehensive environmental data. Its lightweight (1.25kg) and compact dimensions (128×185×128mm) make it particularly suitable for large-scale air quality monitoring network deployment. With RS232/RS485 local connectivity, Modbus protocol support, and open API interfaces, the system ensures seamless integration and data sharing. Typical applications include urban air quality grid monitoring, industrial emission surveillance, and roadside/tunnel environment monitoring. The device requires maintenance only every 12-24 months and operates at 0.5W power consumption, demonstrating energy-efficient performance. 45711
