Product Description 
 ETW-air microbial sampler details: 
 ETW-2 air microbial sampler is a small portable samplers. Available for health care, food industry, fermentation industry, the pharmaceutical industry, agriculture and animal husbandry as well as the research department for monitoring and experimental studies of microorganisms in the air a new instrument. 
 The same type of instruments and international instruments, with a broader scope of application, small size, flexible, comprehensive feature of the device; capture rate and the international standards of microorganisms in the air sampler has the same level 
 ETW-air microbial sampling of the structure characteristics: 
 1, the instrument is a small solid percussive samplers. Microorganisms in the air through the sampling device on the end cap 18 holes nozzle to produce the high-speed motion, the aerosol particles hit the surface of sampling media in plastic petri dish. 
 , The instrument impeller design of inclined holes in the sampling process, the internal impeller driven by high-speed airflow is automatically rotated so that the collection of microorganisms evenly distributed in the agar surface, without additional electric or mechanical structure of the winding start greatly reduced the size and weight of the sampling device. 
 3, this instrument is to facilitate sampling, the use of imported microcontroller, program control electronic timer, in the case of the uninterruptible power supply, storage memory (can repeat the last regular operation). 
 4, the instrument 701BB Series gas rotameter. The temperature effect is small, the flow is more stable. Rubber tube curvature of the links on the internal structure of the instrument, the less resistance in the gas path. 
 5, the instrument using advanced dual-loop electromagnetic pump structure, with a stable output, low noise, long life characteristics. 
 6, the instrument is small size, light weight, portable, simple operation, without requiring additional equipment. Has 220V, 50HZ AC power can be used. 
 ETW-air microbial sampler of technical specifications: 
 A flowmeter range 3 - 25 l / min. Typically use 20 liters / min. 
 2, made of wax-like bacteria Bacillus aerosols. The measured capture rate above 95% in the standard aerosol chamber. 
 Timer: Electronic Timing: maximum time of 99 minutes, the error precision of less than 10 seconds. 
 4, Power: AC 220V ± 10% 50HZ. 
 Power consumption ≤ 45W. 
 6, noise ≤ 68ab. 
 7, size: 290 × 220 × 200 mm3 and 
 8, Weight: 7Kg
