Overview
AQM-800 waterproof Multi-Parameter dust detector is a new generation of environment monitoring instrument developed by Beijing Judao Hesheng Technology Co., Ltd. It adopts an explosion-proof closed shell, which has the characteristics of anti-drop, pressure resistance and good airtightness to effectively protect the internal instrument. The equipment is designed with an external sampling device, which can automatically monitor in the closed shell state, realize airtight, waterproof and dustproof, and is suitable for regular monitoring in rainy days or harsh environments. The internal laser dust monitoring system is independently developed, which can monitor multiple particle size dust concentrations at the same time, without changing the cutter. The instrument is compact and portable, sturdy and durable. It is suitable for environment air flow monitoring. It has both mobile and fixed-point monitoring modes, and supports data aggregation and communication interconnection.
Features
1. Can display multiple particle size measurement data at the same time, no need to replace the cutting head
2. 4.5 inch Touchscreen design, Chinese Operating interface, easy to operate
3. Optical inspection standard loose board inside to ensure high Stability of instrument
4. Built-in filter membrane sampling device can continuously monitor particulate matter (PM) and collect dust samples, which is convenient for composition analysis and mass concentration conversion factor K value calculation
5. Design a constant current controller to ensure that the Sampling flow rate is constant and the cutting Linear dispersion is correct
6. With protective air curtain, avoid dust pollution Optical inspection system to ensure high Reliability
7. Data supports wired transmission, GPRS wireless transmission, radio transmission or network port transmission and other methods
8. Real-time display of dust mass concentration (mg/m ³), results in one minute
9. Alarm threshold for dust concentration exceeding standard can be set to achieve explosion-proof warning
10. Optional Humidity correction function to obtain accurate data in Humidity environment
Principle
The instrument adopts self-developed laser dust monitoring system, detects dust concentration through Optical inspection principle, and is equipped with Optical inspection standard loose board to ensure Stability. A constant current controller is designed to keep the Sampling flow rate constant and protect the air curtain from dust pollution core Optical inspection components to achieve high Reliability monitoring.
Applications
Rapid determination of inhalable particulate matter (PM) concentration in public places, central air conditioning exhaust port concentration detection, dust concentration detection in industrial and mining enterprises, inhalable particulate matter (PM) concentration monitoring in the field of environment protection, air purifier purification efficiency evaluation
Steps
1. Power on the instrument
2. Set monitoring parameters and Alarm threshold through Touchscreen
3. Activate automatic monitoring, external sampling device works under closed housing
4. View data display and transmit data in real time
5. Optional Humidity correction function for environment adaptation
6. Collect dust samples for subsequent analysis
Notice
• The instrument should be used in the environment specified by the explosion-proof mark Exib ⅱ BT4Gb
• Avoid prolonged exposure to extreme conditions to avoid affecting performance
• Periodic inspection of sampling devices and Optical inspection systems to ensure no contamination
• Select the appropriate method for data transmission to ensure a stable connection
Alarm threshold setting refers to the actual application requirements to avoid false alarms
