Scope of Application：

This instrument is suitable for TSP sampling in environmental emergencies and environmental assessment sites, and is optimized for heavy metal and source apportionment sampling. It is an ideal instrument for environmental monitoring departments at all levels, disease control centers, industrial and mining enterprises, military and scientific research and education institutions.

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. Optional atmospheric constant current sampling, using imported thin film pump, automatically accumulates sampling standard volume;

3. The total suspended particulate matter (TSP) or inhalable particulate matter (PM10, PM5, PM2.5) in the instrument adopts imported brushless motors with a lifespan of over 20000 hours;

4. 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;

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

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

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

8. Optional printer data output;

9. Equipped with semiconductor heating and cooling functions, ensuring constant temperature atmospheric sampling (ZC-Q0222 has functions);

10. Rainproof and dustproof design.
