Dust online monitoring instrument inspection report

Advantages of AML-YC07 Construction Site Dust Pollution Online Monitoring System:

1. The monitoring system of the entire equipment is designed to measure pollution sources with high flow rates introduced into quasi containers using pump suction light scattering method. The pump flow rate is 2.83 liters/minute and the range is 0.001-50mg/m3
The accuracy of data measurement is higher with larger pump suction and suction flow rate per unit time;
The introduction of large flow of pollution sources ensures that the pollutants entering the detection chamber truly reflect the current situation of the pollution source;
The quasi container diversion ensures a constant flow rate of pollutants introduced into the detection chamber and stable air pressure, ensuring that pollutants pass through the measurement chamber at a constant speed and pressure.
2. The entire equipment sampling system adopts heating and dehumidification function to ensure the accuracy of measurement data while weather changes, especially for rainy and snowy weather and hot weather in summer.
3. The entire equipment has a self-cleaning function. In order to ensure the accuracy of measurement data, the sampling pipeline, detection chamber, and sensors of the equipment are contaminated by particulate matter in the air after a period of operation, resulting in inaccurate measurement data. Therefore, the equipment must have a self-cleaning function to automatically clean and zero the sampling pipeline, detection chamber, and sensors periodically.
4. Data validity assessment. The whole set of equipment truly achieves digital Internet analysis, accurately judges the location and direction of the source of pollution, and accurately analyzes and judges the validity data of the pollutant data of the detected site.
5. The device has strong compatibility and can be compatible with sprinklers LED、 Supporting facilities such as fog cannons and police lights.
6. The data transmission strictly follows the communication protocol and backend data analysis platform docking of the National Environmental Protection Department's pollution source online automatic monitoring (monitoring) system data transmission standard (HJ/T212-2005).
