The analysis of the filtering effect of the dust particle counter filter can mainly be carried out from its working principle, technical characteristics, application fields, and actual usage effects.

1、 Working principle

The dust particle counter measures the number and size of suspended particles in the air through the principle of light scattering. When air is introduced into the counter and passes through a small air pump and precision filter, the particles in the air are separated. These particles are then irradiated by a laser source, and the laser beam is projected onto a photodiode through an optical system. When particles pass through, they block a portion of the laser, generating a light pulse signal. After amplification and discrimination, this light pulse signal is recorded by the counting system to measure the number and size of particles in the air.

2、 Technical features

High precision: Dust particle counters can measure very small particles, typically detecting particles of 0.1 μ m or larger.

Multi channel detection: Some high-end dust particle counters support multi-channel detection, which can simultaneously measure particles of multiple sizes to meet different detection needs.

Built in filter: Some dust particle counters are equipped with HEPA filters, which can filter the discharged air and reduce environmental pollution.

Intelligence: Modern dust particle counters are usually equipped with intelligent software systems that can automatically perform data statistics, analysis, and output detection result reports.

3、 Application Fields

Dust particle counters are widely used in environments that require high cleanliness, such as semiconductor integrated circuit factories, optical laboratories, clean workshops, biological laboratories, pharmaceutical factories, etc. In these fields, the filtering effect of dust particle counters is directly related to the quality of products and the cleanliness of the production environment.

4、 Actual usage effect

In practical use, the filtering effect of dust particle counters is mainly reflected in the following aspects:

Accurate measurement: capable of accurately measuring the quantity and size of suspended particles in the air, providing reliable basis for the assessment of cleanliness.

Real time monitoring: It can monitor the concentration changes of particles in the production environment in real time, and promptly detect and deal with potential pollution sources.

Efficient filtration: The built-in high-efficiency filter (such as HEPA filter) can effectively filter the discharged air and reduce secondary pollution to the environment.

Improving product quality: By ensuring the cleanliness of the production environment, dust particle counters help to enhance product quality and stability.

Above all, the dust particle counter filter performs excellently in terms of filtering effect, with features such as high precision, multi-channel detection, built-in filters, and intelligence. In practical applications, it can accurately measure the quantity and size of suspended particles in the air, monitor real-time changes in the cleanliness of the production environment, and reduce environmental pollution through efficient filtration. These characteristics make the dust particle counter an indispensable and important tool in clean room detection.
