AQM800 online waterproof multi-particle size Detector is a new generation of environmental monitoring instrument newly developed and produced by Beijing Judao Hesheng Technology Co., Ltd. It adopts an explosion-proof airtight shell, which is anti-drop, compression-resistant, and has good airtightness, which protects the internal instrument from the external environment.
The equipment is designed with an external sampling device, which can be automatically monitored in the state of closed shell, so as to achieve the effect of sealing, waterproof and dustproof, and is more suitable for regular monitoring in rainy days or harsh environments. Its internal components adopt our company's self-developed laser dust monitoring system, which can monitor the dust concentration of multiple particle sizes in the regional environment at the same time, without replacing the cutter. The design of the instrument is exquisite, and the external sampling device can be stored in the instrument box, which is easy to carry, durable, and suitable for monitoring the flow of ambient air, and has strong practicability. In addition, the online AQM-800 has mobile monitoring and fixed-point monitoring mode, which can be used as a portable machine, and can also be used as a monitoring substation, and the measured data can be summarized to the central station through modern network technology, or to realize the communication and interconnection of multiple monitoring stations.
This instrument conforms to the relevant provisions of the National Metrology Verification Regulations "Light Scattering Digital Dust Tester" JJG 846-1993. It is suitable for the rapid determination of the concentration of inhalable particulate matter in public places, the concentration detection of the exhaust port of central air conditioning, the detection of dust concentration in the production sites of industrial and mining enterprises, the monitoring of the concentration of inhalable particulate matter in the field of environmental protection, and the evaluation of the purification efficiency of air purifiers.
1. It can display the measurement data of multiple particle sizes at the same time, without replacing the cutting head
2. All adopt 4.5-inch touch screen design, Chinese operation interface, easy to operate.
3. Built-in optical standard loose plate to ensure high stability of the instrument.
4. The built-in filter sampling device can collect dust samples while continuously monitoring the particles in the air, so as to analyze the composition and use the filter weighing method to find the mass concentration conversion coefficient K value.
5. The constant current controller is designed to ensure that the sampling flow is constant and the cutting curve is correct.
6. It has a special protective air curtain to avoid the pollution of dust to the core component of the instrument - the optical system, and ensure the high reliability of the instrument
7. The data can be transmitted by wired transmission, GPRS wireless transmission, radio station transmission or network port transmission
8. Real-time display of dust mass concentration (mg/m³), one minute out of the result
9. The alarm threshold of dust concentration exceeding the standard can be set to play the role of explosion-proof early warning
10. Humidity correction function can be selected, and accurate data can be obtained in a humid environment.

Waterproof housing, touch screen control, multi-particle size monitoring, no need to change the cutting head
FeaturesExplosion-proof enclosed shell, anti-drop, compression-resistant, good sealing, can be monitored in rainy days or harsh environments.
Applications:Environment, public environment monitoring, air quality monitoring, disease control and other fields
