With the development of modern biotechnology, biosafety has attracted the close attention of scientists and technicians in the field of biology. Generally speaking, for the safety of biological experiments, the experiment is usually carried out in a clean room. Clean room refers to the place where people can work when the air cleanliness reaches the specified level, and its function is to control the pollution of particulate matter. In general, according to the use can be divided into industrial clean room and biological clean room. The industrial clean room takes inanimate particles as the control object, while the biological clean room mainly controls the pollution of microorganisms to the work object.

In addition, the clean room also needs a lot of purification equipment, such as air inlet system, return air system, self-cleaning device, clean shed, buffer and so on. All this is to produce and manufacture products in a good environmental space. In a clean room, we need instruments to measure the number and size distribution of dust particles in the air, which can provide a basis for the evaluation of air cleanliness. Laser dust particle counter is an instrument for measuring the number and size distribution of dust particles in the air.

Laser dust particle counter is a measuring instrument used to detect the air cleanliness level in clean room workshops, which can meet the needs of the pharmaceutical industry (pharmaceutical factories, drug inspection offices, hospital operating rooms, etc.); Electronics industry (semiconductor factories, production and processing of precision machinery, etc.); Food hygiene industry (finishing of dairy products, plastic sealed meat products, seasoning food, agricultural products, etc.); Filter manufacturers, check the quality and efficiency of filters, etc; the clean room (area) required for finishing and precision testing in the fields of optics, aerospace, etc.

The dust particle counter is mainly based on the particle size and distribution of dust particles in the environment to determine its cleanliness. Usually the cleanliness level is100Level--100000In the clean room of the class, the selection accuracy is0.5umThe dust particle counter can meet the requirements. Of course, if funds permit, you can choose.0.3umEven the following dust particle counter.

At present, Shenzhen Technology Co., Ltd. is the agent of Alpha.OPC-N3It is a sensor that can be used to detect particulate matter in clean rooms. The number of particles per unit volume can be detected by using laser scattering and particle size counting principles.OPC-N3Some of the performance parameters are as follows:
