ZAQM-1000The multi parameter dust detector is a new generation environmental monitoring instrument developed by our company. This instrument can display measurement data of multiple particle sizes simultaneously without the need to replace the cutting head, saving customers measurement time and cost, and meeting their technical requirements for data collection and comparison.

Detecting environmental dust concentration through the principle of laser light scattering. By using a laser light source, the response speed is improved, and the conversion coefficient of mass concentration is not affected by the color of particles, ensuring the accuracy of measurement data. The instrument consists of rechargeable batteries, circuit boards, optical detection chambers, and air pumps. Scalable online multi particle size dust detection equipment6One particle size parameter enables the simultaneous acquisition of measurement data for multiple particle sizes on a single host without the need to replace the starting head. It has both mobile monitoring and fixed-point monitoring modes, and can be programmed for fixed-point monitoring. It can also achieve communication and interconnection among multiple monitoring stations and data aggregation to the central station through modern network technology, with strong usability. Built in filter membrane sampling device can collect dust samples while continuously monitoring particulate matter in the air for component analysis and determination of mass concentration conversion coefficientKValue. By using this system to monitor the concentration of suspended particulate matter in the atmosphere in real time and the proportion of particles of different sizes, combined with meteorological parameters, the interaction and influence between various technical indicators in the local environment can be analyzed, providing decision-making basis for manual intervention.

This system has changed the current situation of one machine and one parameter for air quality monitoring instruments, achieving the goal of simultaneous monitoring and integrated display of multiple parameters, improving the ability and automation level of air quality monitoring, reducing the influence of human factors on data during the monitoring process, and greatly improving the accuracy of monitoring. This product has the characteristics of saving measurement time and cost, meeting customers' technical requirements for data collection and comparison, and has a broad market prospect!

PCIntroduction to End Software (Online Optional)

1This system software is a green version and does not require installation.

2The system software can display in real-time by connecting dust detection equipmentPM10、PM5、PM2.5、PM1、TSPEqual particle size dust concentration.

3The system can perform two measurement modes: response mode and automatic reception mode.

4The response mode can measure dust parameters, and various measurement parameters can be set in the "Settings" area: sampling time, waiting time, range, and humidity correction. Users can freely control the collection time.

5The automatic receiving mode only requires opening the communication port and selecting the automatic receiving mode. The operation is simple, and the uploaded data will be automatically displayed and saved.

6Range provides automatic range, rangeX1RangeX10Three choices.

8The software also provides the function of viewing line charts of various parameters. The line chart takes a random measurement result every hour during the measurement period, which can be viewed for recent times24Measurement data of one measurement point.

9The software automatically generates daily log files and measurement data files, automatically saves communication records and data, and users can access them in the root directory of the softwaredateandlogView data records and communication logs in the folder.
