System Introduction

The LGH-01 Ambient Air Quality Continuous Automatic Monitoring System, developed by Anhui Landun Photoelectron Co., Ltd., is tailored to meet China’s environmental standards. This cutting-edge system integrates optics, mechanics, electronics, and computer technology, utilizing the open-path long-path analysis method recommended by the National Environmental Protection Agency and the beta-ray absorption method endorsed by the USEPA. The open-path method employs optical differential absorption spectroscopy, allowing for the simultaneous monitoring of multiple trace pollutants. Compared to traditional point instruments, it provides significant advantages, including continuous online measurement, stable operation, a wide measurement range (with remote sensing capabilities), low operational and maintenance costs, shorter maintenance intervals, and the ability to operate without the need for personnel supervision.

The complete system comprises a long-path differential absorption spectroscopy (DOAS) gas monitor, CO analyzer, PM??and PM?.? monitors, a meteorological station, and a data acquisition system.

Pollutant Monitoring Methods:

Technical Features

Strong Representativeness: The open-path long-path monitoring area offers high representativeness.

Simultaneous Gas Monitoring: Capable of monitoring multiple gas components at once, with easy expansion for other pollutants.

Fully Non-Contact Automated Monitoring: This technology requires no sample extraction, eliminating inaccuracies from sampling and accurately reflecting atmospheric pollution conditions.

Average Pollution Assessment: Provides an average pollution status across the monitored area without the need for multiple sampling points.

Simple Structure: High integration level makes maintenance easy.

Cost-Effective Operation: No special consumables are required, with long replacement cycles and minimal maintenance, resulting in low operational costs.
