Introduction: The SX-L301H handheld dust particle counter is a portable instrument for measuring air pollution and measures the number of airborne dust particles and the AQI Ambient Air Quality Index. Particle counters are designed and manufactured based on the principle of particle scattering. When a particle is irradiated by a beam of light, its surface will produce scattered light. The intensity of the scattered light is proportional to the intensity of the light source and the size of the particle. When the intensity of the light source is constant, the particle size can be obtained by the intensity of the scattered light. Particle counter is a special instrument for testing the particle size and distribution of airborne dust particles. It has been developed by microscope. It has undergone various functions such as microscope, sedimentation tube, sedimentation instrument, centrifugal sedimentation instrument, particle counter, laser air particle counter, , Multi-channel multi-function particle counter and other processes, is widely used in various provinces and municipalities Drug Procuratorate, Blood Center, Epidemic Prevention Station, Disease Prevention and Control Center, Quality Supervision, and other authorities; also widely used in electronics, pharmaceutical, semiconductor, optical Or precision machining, plastic, painting, hospitals, environmental protection, inspection and other production enterprises and research departments. Technical Parameters: Model: LZJ-01D Sampling rate: 2.83 l / min (0.1cfm) Sampling error: ≤ ± 5% The maximum measurable particle concentration: ≤ 30K / L Particle size channels: 0.3, 0.5, 1, 3, 5, 10um (0.3um signal to noise ratio ≥2.5: 1) Self-purification time: ≤ 10min Particle size distribution error: ≤ ± 30% Indication of particle concentration error: ≤ ± 30% Relative repeatability of measurement: ≤ ± 10% Data communication interface: USB, RS232 The maximum communication speed: 9600BPS Power: Laser diode (life is more than 3000 hours) Current: DC7.2V, 1800mAh Weight: 0.98Kg Dimensions: 125 * 230 * 43 (L * W * H) mm Use of the environment: Working environment: 15 ~ 30 ℃, 10-85% RH Storage environment: -10 ~ 50 degrees Celsius, 10-58% RH Cleanliness level to determine the standard: ISO14644 FS209E
