Product Overview

execution standard

• HJ 653-2013 Technical Requirements and Detection Methods for Continuous Automatic Monitoring System of Environmental Air Particulate Matter (PM10 and PM2.5)
• HJ 1100-2020 Guidelines for Automatic Monitoring of Particulate Matter (PM10 and PM2.5) in Environmental Air by Beta Ray Method

Product Features

• The whole machine is highly integrated, and different analysis factor modules can be combined arbitrarily, suitable for large-scale grid layout
• Particle monitoring adopts the β - ray absorption method, which is not affected by seasonal changes and does not require correction. It provides accurate data in real-time around the clock
• Using DHS (Dynamic Heating System) to heat the sampling inlet gas and with dynamic temperature and humidity compensation function, ensuring accurate 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 electrode high-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 advanced temperature and humidity compensation algorithms to correct the impact of temperature and humidity on measurement, ensuring accurate measurement results
• Built in 4G data transmission module (DTU), capable of data upload, data transmission complies with the "Data Transmission Standard for Pollution Source Online Monitoring (Monitoring) System" (HJ 212-2017)
• Can achieve remote reading of system status information, remote control, remote modification of instrument parameters, fault diagnosis, etc
• The instrument can remotely upgrade terminal applications and update system functions in a timely manner through an FTP server
• Made of stainless steel material, able to adapt to complex environments around the clock, with electronic compatibility design, as well as dust-proof and waterproof design
• The circuit part adopts industrial grade embedded processors, which can be used in severe cold weather with a working environment temperature range of (-40-70) ℃
• The instrument is equipped with a small lithium battery, which can monitor abnormal situations such as power outages on site and report them to the platform
• The sampling data is automatically memorized, and the current data is automatically saved after a power outage. The instrument can continue sampling after a power outage
• Massive data storage capacity, capable of storing up to 365 days of data, supports USB drive export
