1. Product introduction

The JCH-2400-4 intelligent four - way constant temperature and constant current 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.

3. Product Features

1. Small size, light weight, easy to carry and easy to operate;
2. Semiconductor constant temperature technology, good constant temperature effect;
3. High-performance ultra-bass imported diaphragm pump, greatly improving stability, long service life and ultra-low noise;
4. The 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. The high-quality dust filter element realizes the particle filtering function, prevents entering the gas path and interferes with sampling, and protects the sampling pump and gas path at the same time;
6. Electronic flowmeter automatically and accurately controls flow, no flow fluctuation, constant current sampling, excellent flow calibration software, convenient flow calibration;
7. Real-time monitoring of pressure and temperature, automatic compensation of flow deviation, and further optimization of flow accuracy;
8. Four-channel design, flexible sampling method, can collect four kinds of gases or two groups of parallel samples, and can be controlled separately;
9. Chinese LCD screen with automatic contrast adjustment, suitable for sampling in cold areas, popular software display interface, achieve good Human-computer interaction;
10. Automatically measure the ambient temperature and automatically heat to prevent the test solution from freezing and is suitable for placing in different specifications of absorption bottles;
11. High-quality and stable tripod stand for automatic height adjustment, suitable for sampling in harsh climates;
12 , Automatically calculate the cumulative sampling volume, and convert the standard sampling volume according to air pressure and temperature at the same time;
13. Atmospheric pressure can be input and measured, suitable for use in low-pressure environments;
14. Sampling data can be stored and printed;
15. Instrument automatic monitoring system In the power supply state, the sampling process has a power-off protection function, and the working data is automatically saved, and the sampling can be resumed after the power is turned on.

16. Optional JCD-1500 upgraded mobile power box can realize normal sampling without AC power
