Introduction 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, laborprotection, 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 2.With nimh battery it can work continuously more than 8 hours 3. Undervoltage indication 4.Power off automatically 20 mins after no operation 5. the memory function, automatically store last acquisition time 6.High strength ABS shell 7.Needle core valve mechanical adjustment, fine scale ,high flow stability 8.Powerful inner diaphragm pump, imported motor drive Technical parameters 1.
