- JCH-2400-1 dual-channel atmospheric sampler (hereinafter referred to as the sampler) is mainly used to collect gaseous and vaporous SO2, NOx, etc. in the air. The product has stable performance, convenient operation , and has been greatly improved in terms of small portability and flow stability, which greatly reduces labor intensity. The sampler uses the solution absorption method to collect various harmful gases in the ambient atmosphere and indoor air. 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 , testing companies and other departments.

1. Sampling two-way design, flexible sampling method, can collect two kinds of gas or parallel samples, and can be controlled separately.
2. The electronic flow meter automatically and accurately controls the flow, the flow has no fluctuation, and the constant current sampling.
3. The use of high-performance ultra-bass 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 filter particulate matter, prevent entering the gas path to interfere with sampling, and protect the sampling pump and gas path at the same time.
6. Real-time monitoring of gauge pressure and temperature, automatic compensation of flow deviation, and further optimization of flow accuracy.
7. 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.
8. Automatically calculate the cumulative sampling volume, and at the same time convert the standard sampling volume according to air pressure and temperature.
9. Atmospheric pressure can be input and measured, suitable for use in low pressure environment.
10. Sampling data can be stored and printed.
11. The instrument automatically monitors the power supply status of the system. The sampling process has a power-off protection function, automatically saves the working data, and can resume sampling after a call.
