TR-9300A Miniature Ambient Air Quality Monitoring System

Product Introduction

The TR-9300A Miniature Ambient Air Quality Monitoring System is designed for continuous, all-weather monitoring of particulate matter and gaseous pollutants in ambient air. It integrates light-scattering particle detection, high-precision electrochemical sensors, GPS positioning, and 4G communication to monitor six key air quality parameters: PM2.5, PM10, SO₂, NO₂, O₃, and CO.

With a compact design, flexible installation options, and remote monitoring capabilities, the TR-9300A supports grid-based air quality monitoring in urban residential communities, commercial districts, industrial parks, traffic corridors, and construction sites. Optional wind speed, wind direction, video, noise, and LED display modules allow the system to be adapted to different environmental monitoring requirements.

Performance Features

2.High-Precision Detection: Combines light-scattering technology for particulate matter with electrochemical sensing for gaseous pollutants.

3. Flexible Configuration: Supports optional wind speed, wind direction, video surveillance, noise monitoring, and LED display modules.

4. Environmental Compensation: Includes temperature and humidity correction, span correction, and automatic compensation for cross-interference between pollutants.

5. Humidity Control: A patented heated desiccant design helps reduce the influence of high humidity on particulate matter measurements.

6. Anti-Interference Inlet: A specialized air inlet helps prevent interference from mosquitoes, leaves, and airborne fibers.

7.Remote Maintenance: Modular components simplify maintenance and calibration, with local and remote calibration, remote maintenance, and remote software upgrades.

8. GPS Positioning: Provides location information for distributed monitoring networks.

9. Reliable Data Transmission: Supports multi-center data transmission and breakpoint-resume transmission, with a stated effective data transmission rate above 98% when used with the platform's data supplementation function.

10. Flexible Power Supply: Supports electrical power or solar power for different installation environments.

Working Principle

The TR-9300A combines two primary detection technologies:

•  Light Scattering: Measures PM2.5 and PM10 by detecting light scattered by airborne particles. The system processes the scattering signal to estimate particulate matter concentrations.

• Electrochemical Detection: Measures CO, O₃, SO₂, and NO₂ using high-precision electrochemical sensors that generate electrical signals in response to target gases.

The system uses temperature and humidity correction, pollutant cross-interference compensation, and data acquisition technology to improve measurement stability. GPS positioning and 4G communication support location-based monitoring and remote data transmission.
