LY-2092 is an all-weather outdoor automatic ambient air quality monitoring terminal for real-time online monitoring. It measures PM2.5, PM10, O3, SO2, CO, NO2, TVOC and five meteorological parameters including temperature, humidity, atmospheric pressure, wind direction and wind speed. Particulate monitoring uses dual-channel beta-ray absorption method for simultaneous PM2.5/PM10 detection. Gaseous pollutants adopt electrochemical sensors and PID detection technology. With stainless steel structure, IP55 protection, industrial-grade circuit and wide-temperature design, the instrument runs stably in complex outdoor environments and supports 4G remote data transmission, remote control and fault diagnosis. It is widely used in urban grid monitoring, industrial zones, road traffic and construction site dust supervision.
Adopts dual-channel beta-ray absorption method to realize simultaneous real-time monitoring of PM2.5 and PM10 with high stability, no seasonal correction and full-day accurate data output.
Equipped with dynamic heating system (DHS) and real-time temperature-humidity compensation, effectively ensures accurate measurement of semi-volatile nitrates and organic compounds.
Uses four-electrode high-precision electrochemical sensors and imported PID sensor for TVOC. Supports on-site standard gas calibration, automatic and manual zero calibration, with strong anti-interference and low drift.
Integrates particulate matter, six types of gaseous pollutants and five meteorological parameters in one unit. Modular design supports free combination and large-scale grid-based deployment.
Made of stainless steel with IP55 dustproof and splash-proof rating. Industrial-grade embedded processor supports wide temperature operation from -40°C to 70°C.
Built-in 4G DTU for data upload compliant with HJ 212-2017. Supports remote status query, remote control, parameter modification, fault diagnosis and FTP remote program upgrade.
Built-in lithium battery ensures data recording and reporting during power failure. Automatically saves data when power off and resumes sampling after recovery. Supports up to 365 days data storage and USB drive export.
Adopts single-pump dual-path sampling with simultaneous sampling and detection at the same position, fundamentally eliminating errors caused by moving filter tape.
