ISO14644-1 clean room can be divided into two general directions for division. One is divided into 1, 2, 3, 4, 5, 6, 7, 8, 9 according to the cleanliness level. Level 9 is the lowest level. Second, according to the airflow organization, ISO14644-1 clean rooms can be divided into three categories: unidirectional flow, laminar flow, and ISO14644-1 clean rooms. Airflow with parallel streamlines in a single direction and uniform wind speed across the cross section. The unidirectional flow perpendicular to the horizontal plane is vertical unidirectional flow and the unidirectional flow parallel to the horizontal plane is horizontal unidirectional flow. Turbulence non-unidirectional flow ISO14644-1 clean room Any ISO14644-1 clean room with airflow that does not meet the definition of unidirectional flow.
Mixed flow ISO14644-1 cleanrooms: ISO14644-1 cleanrooms with combined flow of unidirectional and non-unidirectional flow. According to the category of suspended particles in the air that the ISO14644-1 clean room needs to control, the ISO14644-1 clean room can be divided into industrial ISO14644-1 clean room and biological ISO14644-1 clean room. Industrial ISO14644-1 clean room, its main control parameters are temperature, humidity, wind speed, airflow organization, cleanliness. Biological ISO14644-1 clean room It is the same as the industrial ISO14644-1 clean room. The difference is that the control parameters increase the concentration of bacteria in the control room.
For the ISO14644-1 clean room, I need to monitor its parameters in real time to ensure that it meets the standards used. For the monitoring of various parameters in the ISO14644-1 clean room, we need to use special monitoring equipment.
Product recommendation: SX-L301N type high-concentration particle production new generation 2.83L/min touch screen particle counter and diluter are organically combined to form an integrated machine, which is convenient for users to detect particles of different concentrations in different occasions. The particle counter is a special instrument for the particle size and distribution of air dust particles. It was developed from a microscope and has experienced microscopes, sedimentation tubes, sedimentation instruments, centrifugal sedimentation instruments, particle counters, laser air particle counters, condensation nucleus particle counters, Processes such as multi-channel multi-function particle counters are currently widely used in authoritative institutions such as drug inspection institutes, blood centers, epidemic prevention stations, disease prevention and control centers, and quality supervision institutes in various provinces and cities; they are also widely used in the electronics industry, pharmaceutical workshops, semiconductors, optics or Precision machining, plastics, painting, hospitals, environmental protection, inspection institutes and other production enterprises and scientific research departments. The all-in-one machine can be used not only for particle detection in the purification area, but also for particle detection in the high-concentration particle area.
SX-L301N type high concentration particle counter
When using an optical particle counter to measure the number of particles in a high-concentration particle aerosol system (particle concentration ≥ 3×〖10〗^4/L), it is necessary to dilute the particle concentration to a range below the upper limit concentration of the optical particle counter to be correct. count.
