Scope of Application：

This instrument is suitable for TSP sampling in environmental emergencies and environmental assessment sites, and is optimized for sampling fluoride and SVOCs. 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：

Under different configurations, the instrument can collect total suspended particulate matter (TSP) or inhalable particulate matter (PM10, PM5, PM2.5); Adopting imported brushless motors with a lifespan of over 20000 hours;

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

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

4. The particulate matter sampling section adopts imported pressure and flow sensors, combined with advanced pulse width regulation automatic control, with good dynamic characteristics, stable flow rate, and maximum cumulative sampling flow rate;

5. The maximum cumulative flow rate for sampling is 9999.9 cubic meters, which can be sampled continuously for 72 hours;

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

7. Automatically save the set parameters and previous sampling data when the power is cut off, and have the function of self starting when the power is on;

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

9. Optional printer data output;

10. Small flow rate (16.7L/min, 50L/min) and medium flow rate (100L/min) sampling can be set;

11. Rainproof and dustproof design.
