Dust particle counter is an instrument for testing the particle size and distribution of air dust particles. It was developed from microscopes and experienced microscopes, sedimentation tubes, centrifugal sedimentation meters, sedimentation meters, particle counters, laser air particle counters, and condensation nucleus particle counters. , Multi-channel multi-function particle counter and other processes, because the laser air dust particle counter has many advantages such as fast detection speed, wide dynamic walking, and no human influence, it has become the mainstream equipment for many occupations for many years. It is currently widely used in various provinces. Municipal Drug Inspection Institute, Blood Center, Epidemic Prevention Station, Disease Control Center, Quality Supervision Institute and other institutions, electronics industry, pharmaceutical workshop, semiconductor, optical or precision machining, plastics, painting, hospitals, environmental protection, inspection institutes and other manufacturing enterprises and scientific research departments .
1. What do you think of the accuracy of the dust particle counter?
Dust particle counter mainly judges its cleanliness through the particle size and distribution of dust particles in the environment. Generally, in a clean room with a cleanliness level of 100 to 100,000, a dust particle counter with an accuracy of 0.5um can meet the requirements.
Of course, if the financial conditions permit, a dust particle counter of 0.3um or less can be used. Users should purchase dust particle counters according to their own needs when purchasing dust particle counters to avoid unnecessary waste.

2. How to identify the grade of laser dust particle counter?
In the purchase of dust particle counters, there are many varieties, which increase the choice and increase the difficulty of selection. Generally speaking, the high-precision large-flow laser dust particle counter has a higher technical content.
The key components and signal processing system in the dust particle counter are the key to distinguish the pros and cons of the laser dust particle counter. Liquid crystal display is a higher level than digital tube display technology. Jin port devices have low operating noise, high sensor accuracy and long life, more scientific signal processing system, high circuit integration, and strong "anti-piracy" ability.

3. What are the issues that should be paid attention to when purchasing a dust particle counter?
In the purchase of particle counters, there are many types of particle counters available. The user should first choose the particle counter that meets the usage needs, and then consider the price of the particle counter. At present, the market products are mainly desktop and portable particle counters. According to the light source, it is a competition between white light and laser particle counters. The performance is a comparison between domestic and imported particle counters.
Desktop and portable particle counters have big differences in flow and accuracy, as well as product technology and devices, but the trend of portable replacement of desktops is becoming more and more obvious. White light and laser particle counters mainly have big differences in test accuracy and product performance, which of course lead to the advantages and disadvantages of prices. The former is inferior to the latter in accuracy, poor performance, and the light source does not have a long service life; however, it is very popular with customers at an ultra-low price. The price difference between domestic and Jinkou particle counters is large, and the product performance is far apart.
