Scope of Application：

This instrument is used for SO₂、 NO_XSimultaneous collection with TSP, using solution absorption method to simultaneously collect various harmful gases in the ambient atmosphere and indoor air; Using filter membrane weighing method to capture total suspended particles (TSP) or inhalable particles (PM10, PM5, PM2.5) in the ambient atmosphere (corresponding cutters need to be added).

3、 Main features：

1. High reliability color touch LCD screen (-30~85 ℃), Chinese menu, easy to operate, can realize single, cyclic and scheduled sampling of the sampler;

2. Imported membrane pumps are used for atmospheric sampling; The particulate matter sampling part adopts imported brushless motors with a lifespan of over 20000 hours;

3. The particulate matter sampling section uses imported pressure and flow sensors, advanced pulse width regulation automatic control, good dynamic characteristics, stable flow rate, and a maximum cumulative sampling flow of 9999.9 cubic meters, which can be continuously sampled for 72 hours;

4. Advanced embedded system hardware and multi-level optoelectronic isolation design ensure the reliability and stability of the system;

5. Automatically save the set parameters and previous sampling data in case of power outage, and have the function of automatic startup upon incoming call;

6. Automatic atmospheric pressure measurement, automatically converted to standard volume;

7. Optional printer data output;

8. Atmospheric sampling uses electronic flow meters to automatically accumulate the volume of sampled standard conditions;

9. Equipped with semiconductor heating and cooling functions, ensuring constant temperature atmospheric sampling (ZC-Q0122 has functions).
