1. Product introduction
JCH-6120-4 intelligent atmosphere/24 hours/TSP integrated sampler (hereinafter referred to as the sampler) applies the membrane weighing method to capture total suspended particles (TSP) and inhalable particles (PM10) or fine particles in the ambient atmosphere (PM2.5) (optional); a necessary instrument for collecting various polluting gas components (SO2, NOx, etc.) in ambient atmosphere and indoor air for 24 hours by solution absorption method. It can be used for routine and emergency monitoring of gaseous substances and aerosols in environmental protection, health, labor, safety supervision, military, scientific research, education and other departments.

3. Product Features
1. The electronic flow meter automatically and accurately controls the flow, the flow does not fluctuate, and the constant current sampling;
2. The atmosphere has a constant temperature automatic heating function, and all four channels have a constant temperature function;
3. The use of high-performance subwoofer imported diaphragm pump greatly improves stability, long service life and ultra-low noise;
4. The use of high-efficiency anti-suction dryer design can effectively prevent the absorption liquid from being sucked back due to misoperation, and enhance the safety of the instrument;
5. Use high-quality dust filter elements to achieve particle filtering function, prevent entering the gas path to interfere with sampling, and protect the sampling pump and gas path at the same time;
6. Four-way design of atmospheric sampling, flexible sampling method, can collect two kinds of gases or parallel samples, and can be controlled separately;
7. The particle sampling adopts brushless control fan, with low noise and large load, suitable for continuous long-term work;
8.TSP/PM10/PM5/PM2.5 (optional) sampling head is made of aluminum alloy material, anti-static adsorption;
9. Real-time monitoring of gauge pressure and temperature, automatic compensation of flow deviation, and further optimization of flow accuracy;
10. Automatic constant temperature device, the constant temperature time is fast;
11. The Chinese LCD screen with automatic contrast adjustment is suitable for sampling in cold areas, and the popular software display interface realizes good human-computer interaction;
12. Automatically calculate the cumulative sampling volume, and at the same time convert the standard sampling volume according to air pressure and temperature.
13. The optional JCD-1500 upgraded mobile power box can realize normal sampling without AC power
14. A set of sample storage device is optional, which is convenient for sample collection and storage
15. Professional metrology certificate issued by the Institute of Metrology
