ZK-3S-based detection of specific indoor air sampler, is based on GB / T 17061-1997 "workplace air sampling equipment technical specifications" in the air sampler performance requirements for the design of the dual air sampler. Instrument specifically designed to meet the air formaldehyde / ammonia / benzene materials / TVOC determination of gases such as equipment and under the sampling requirements, so the sample can be dedicated to the detection of two-way indoor air sampling. 

 This sampler is a dual air pump, two-way flow, computer-controlled handling system (timer), power supply, switch and work instructions, sampling frame composed of several parts. 

 Air pump working pressure for the ultra-stable vacuum suction pump, to ensure constant ventilation and stability. Processing system by computer-controlled feedback control sampling pump and sampling time, the sampler-speed operation to ensure stable gas flow and sampling accuracy. 

 Sampler equipped with rechargeable battery, AC-DC power dual-use, convenient and practical.
