With the rapid development of new energy lithium batteries, semiconductors, biopharmaceuticals, liquid crystal panels and other fields, higher requirements are placed on the cleanliness of the production environment, and it is very important to effectively control the concentration of dust particles in the clean room air. According to the relevant national regulations, after the design, construction and delivery of the clean room, it is necessary to conduct a comprehensive evaluation and analysis of its performance and rationality.
High-precision dust particle counter is a professional instrument used to detect and count the number of particles in the air. The online particle counter adopts the principle of optical scattering. When the laser beam passes through the particles in the air, the particles will scatter the laser light. The high-precision dust particle counter calculates the number and size of particles in the air by measuring the number and intensity of scattered light. It can accurately detect and count the number of suspended particles of different particle sizes in the air per unit volume. It has a built-in dust source intelligent identification module unique to Sifang Optoelectronics. It has a gas sampling rate of 28.3L/min and can simultaneously output 0.3μm, 0.5μm, 1.0μm, 5.0um, 10μm five channels of particles (default unit pcs/28.3L, switchable pcs/m3), indication error full JJF-1190 standard.
High-precision dust particle counters have many advantages. First, the high-precision dust particle counter has high sensitivity. It also accurately detects tiny particles at low particle concentrations. Second, it has high reliability. It can monitor the changes of particles in real time and give accurate data to ensure the quality of the environment. In addition, it has high precision. Through high-precision detection, the occurrence of misjudgment or missed judgment can be avoided.
1. Precautions for the use of high-precision dust particle counters
1. The instrument is forbidden to be used in an environment with high dust concentration, in an environment containing water vapor, oil and corrosive substances, or in an environment with a high temperature exceeding the allowable use.
2. Do not block the inlet and outlet holes, so as not to cause damage to the air pump.
3. The instrument is an integral part, and the user must not disassemble it to prevent irreversible damage.
4. Do not cause large vibrations to the instrument, so as not to affect the internal air tightness.
5. The instrument cannot operate continuously, and continuous operation will shorten the service life of the product.
High-precision dust particle counters are widely used in many fields, including pharmaceuticals, biotechnology, semiconductor manufacturing, laboratories, clean rooms, and hospitals. These areas are environmentally demanding and require precise monitoring and control of the number of particles in the air.
For example, in the pharmaceutical industry, the production of drugs must be carried out in a sterile and clean environment to ensure the safety and effectiveness of drugs. In this case, a high-precision particle counter can detect particles and other pollutants in the air, thereby keeping the production environment clean and hygienic.
Similarly, in a laboratory environment, a high-precision dust particle counter can help scientists monitor the particles in the laboratory air to ensure the accuracy of experimental results. Additionally, in hospitals, the instrument can help monitor airborne particulates in operating rooms, patient rooms, and other areas to keep medical facilities hygienic and safe.
