Introduction: The ETW-2 air microbial sampler adopts the recognized Anderson sampler with large sampling flow and good stability. The power supply adopts AC type, which is convenient to use, small in size and light in weight. It is a powerful tool for on-site microbial sampling. Multi-stage sampler, it can determine the total number of air microorganisms, and can distinguish the number of inhalable (<8mm) and non-inhaled microorganisms. Inhalable microbial aerosol is an important environmental parameter. The particle size distribution requires only the determination of Inhalation and non-inhalation and the total number of bacteria, it is appropriate to use a secondary sampler. Level 6 is more suitable for the implementation of hygienic standards for air conditioning and ventilation in public places. The standard mass flow meter is an indispensable part of the sampling accuracy of the ETW-2 system. Sixth grade use: Indoor air quality; efficiency studies of filters and clean rooms; medicinal products; hospital environment; food processing plants; bacterial growth Technical Parameters: The sampling pump is used for constant flow sampling, and the sampling flow is adjustable from 5 to 30 L/min, usually 20 liters/min. An aerosol made from spores of Bacillus cereus. The capture rate is determined to be above 95% in a standard aerosol chamber. The timing range of the timer: 1-999 minutes is adjustable, the error is not more than ±5‰ (five thousandths). The power supply mode is AC 220V±10%, 50HZ. Power consumption ≤45W. Noise ≤ 68ab. Volume: 290×220×200mm. Weight: 7Kg
