Handheld particle detector

The handheld particle detector is equipped with a high-sensitivity laser sensor and a dynamic temperature and humidity compensation module, which can eliminate environmental interference and ensure data reliability under complex working conditions. Equipped with a color touch screen or OLED display screen, it intuitively displays concentration curves, AQI index, and health risk warnings.

Handheld particulate matter detector is a portable and high-precision on-site detection device designed for rapid measurement of PM1.0, PM2.5, PM10, and TSP (total suspended particulate matter) concentrations in the air. It is suitable for environmental law enforcement, industrial hygiene, indoor air assessment, and emergency monitoring scenarios. It adopts laser scattering method or light absorption principle, with a range covering 0.1~1000 μ g/m ³, measurement accuracy within ± 5%, and supports real-time data display and storage. The device is lightweight and easy to operate, with one hand holding it to complete sampling and quick feedback within 5 seconds

This device monitors the real-time information of workers' work location, duration, inhalable particulate matter concentration STEL, TWA, etc. according to labor hygiene requirements, and conducts data analysis and safety protection measures prompts. It can also be used as a mobile monitoring point for environmental pollution in the factory area, facilitating comprehensive and refined management of workplace hygiene conditions, labor conditions, production equipment leaks, protective measures effectiveness, and other situations. The supporting monitoring system software can be combined with the factory map to link with dust reduction equipment for rapid dust reduction and timely improvement of pollution exceeding standards. It can be widely applied in enterprise management, labor safety, digital production, emergency safety supervision, and other aspects.

Working Principle:

Mainly based on the principles of laser scattering or optics. When particles in the air pass through a laser beam, scattering occurs, and the intensity of the scattered light is proportional to the size and quantity of the particles. These scattered lights are captured by photodetectors and converted into electrical signals. After being processed by a microprocessor, the concentration or quantity of particulate matter in the air can be calculated.

Basic characteristics:

1. A lighter and smaller (weighing 205g) industrial instrument grade individual dust analyzer;

2. Simultaneously measuring multiple parameters such as dust, temperature, and humidity, and reading data in real-time;

3. Large screen, large font full-color touch screen, clear display, easy operation;

4. Simulate human respiratory flow (0.5ml) and monitor individual inhalation in real-time;

5. External zero calibration device, easy to maintain, ensuring measurement accuracy;

6. Large capacity rechargeable dry battery, ultra long standby time;

7. Imported CPU, short measurement response time, short analysis cycle, and large data storage capacity;

8. Standard PC software, capable of data export and instrument setting functions;

9. It can simultaneously transmit data to on-site, remote online, and cloud platforms, enabling real-time viewing on both mobile and PC devices.

Typical application scenarios:

1. Environmental inspection: Quickly screen for excessive dust on construction sites and roads, and collaborate with drones to draw regional pollution heat maps;

2. Industrial production: testing the dust exposure level of welding, polishing, and feeding processes in the workshop, and assessing occupational health risks;

3. Indoor environment: Evaluate the PM2.5 concentration in offices, schools, hospitals, and other places, and guide the use of air purification equipment;

4. Emergency response: After a fire or explosion accident, detect suspended particulate matter, define the pollution area, and guide personnel evacuation.
