Environmental Air Quality Monitor (Dual Channel)

Laoying 2092 Environmental Air Quality Monitor (Dual Channel)

1、 Product Overview

This instrument is an all-weather outdoor automatic monitoring terminal that can automatically monitor real-time parameters such as PM10, PM2.5, O3, SO2, CO, NO2, TVOC, as well as meteorological five parameters (temperature, humidity, atmospheric pressure, wind direction, wind speed). The particle monitoring adopts a dual channel beta ray absorption method, which can achieve simultaneous monitoring of PM10 and PM2.5 concentrations compared to a single channel. The gaseous pollutant monitoring adopts an electrochemical method. This instrument is made of steel material, with electronic compatibility * design, as well as IP55 dustproof and splash proof design, sturdy and durable, and can reliably work in various complex environments.

3、 Product Features

The whole machine is highly integrated, and different analysis factor modules can be combined arbitrarily, suitable for large-scale grid layout

The particle monitoring adopts the β - ray absorption method, which is not affected by seasonal changes and does not require correction. It is provided in real-time 24/7data

Using DHS (Dynamic Heating System) to heat the sampling inlet gas and with dynamic temperature and humidity compensation function, ensuring the measurement of semi volatile nitrates and organic compounds

PM10 and PM2.5 monitoring adopt a dual channel sampling method with one pump, and two sets of high-quality detectors are installed to achieve simultaneous monitoring of PM10 and PM2.5

Particle monitoring sampling and detection are located at the same position, fundamentally solving the measurement error caused by moving paper tape

The monitoring of gaseous pollutants adopts electrochemical method, using four electric precision sensors and imported PID sensors, with high measurement accuracy

The gaseous pollutant pipeline adopts a sealed gas chamber, which can be calibrated on-site with standard gas. It has a zero gas calibration module, which can achieve automatic and manual zero calibration

The gaseous pollutant detection module adopts the temperature and humidity compensation algorithm of * to correct the influence of temperature and humidity on measurement, ensuring accurate measurement results
