1. Product overview

JCH-2112 dual-channel VOCs sampler is a special sampling equipment for TVOCs , benzene, toluene, xylene and other organic substances in ambient air. , Imported sampling pump, high-precision mass flow sensor and high-tech in the field of new materials. It is suitable for sampling of volatile organic, toxic and harmful gases in ambient air, workplace, and industrial production organized emissions. It can be used by environmental protection, health, labor, security, military, scientific research, education and other departments.

2. Technical characteristics

1. Adopt low noise imported brushless sampling pump, high load capacity and long service life;

2. Using PID flow control algorithm, the flow control is more stable;

3. Using high-precision mass flow meter, the flow measurement is more accurate;

4. Dual-channel sampling, each channel can be controlled independently, the sampling method is flexible, and the timing and immediate sampling modes can be set;

5. Built-in high-efficiency lithium battery, dual-channel simultaneous sampling time is more than 8 hours;

6. Built-in 2 - micron double filter, effectively protect the instrument from dust and have a longer service life;

7. Large size, wide temperature and bright color display;

8. With power-down protection function, the sampling data will not be lost during power-down;

9. One machine is multi-purpose, which can realize the sampling of waste gas VOCs , ambient air VOCs , benzene series, etc. at the same time;

10. Large-capacity data storage, single-channel sampling storage data is greater than 1000 groups;

11. Built-in Bluetooth module, optional Bluetooth printer for sampling data printing;

12. Small size, light weight, with tripod, adjustable sampling height ;

13. The moisture separator with built-in semiconductor refrigeration in the refrigeration box is optional, which can effectively remove the moisture in the flue gas and prevent the moisture from entering the adsorption tube and affecting the measurement results;

14. The adsorption tube can be optionally built into the refrigeration box, so that the adsorption tube is in an ideal temperature environment ( 0~5 ℃), and the adsorption efficiency of the adsorption tube is improved;

15. Cascade adsorption tubes can be installed after the main adsorption tube to test whether the adsorption tube penetrates.

16. The inner tube of the optional sampling tube is made of anti-adsorption polytetrafluoroethylene material, and the whole process is heat traced;

17. The optional sampling tube adopts PID high-precision temperature controller, and the control accuracy is better than 2 ℃.
