TWA-500S Low-flow long-period individual air sampler

TWA500S Lowflow longperiod individual sampler is a  common instrument for collecting the gas in 

atmospheric  environment and workshop site 

   It is widely used in atmospheric environment monitoring, sanitation and epidemic prevention, labor

 protection, scientific research, and other units as well as  supporting the use of the  relevant 

instruments. Thesample gas analysis can  indicate the gas pollution degree of the environment , and  provides the

 actual situation of pollution and take countermeasures for the relevant competent departments to, so as to ensure  people a healthy living environment

  The instrument  has the advantages of compact structure, stable performance, small volume, light 

weight, easy to carry which  is an ideal one of small portable air sampling instruments in the present Changing different sampling load can not only collect poisonous gas, but also collectdust and 

activated carbon sampling tube, etc., suitable for multifunctional atmospheric environmental monitoring for multi purpose

 Main features:

1.Micro processing technology, humanized design, liquid crystal display
