Meteorological chromatograph

Meteorological chromatograph is the latest generation of products developed by our company, LCD display in Chinese and English, full digital parameter operation, with high integration, simple operation, high degree of automation, good reliability, long time operation, its cost performance in the forefront of similar products.It can be widely used in petroleum, chemical industry, environment, food safety, disease control, education and scientific research and other fields, can be the organic matter, inorganic matter and gas constant, trace, trace analysis.

Instrumentation features:

1. Adopt 320 x 240 dot matrix 5.7-inch large screen LCD Chinese / English display, each temperature, operating conditions display in real-time, clear and intuitive content,

Truly realize man-machine dialogue;

2. Start-up self-inspection, automatic heating up, wide-range self-diagnosis function, can accurately determine the fault location and alarm;

3. Six-way independent temperature control (vaporization room, capillary vaporization room can independently control the temperature), and the heating function of the eighth-step program;

4. Overtemperature protection function: if any one of the roads exceeds the set temperature, the instrument will automatically power off and alarm;

5. The unique vertical heating device makes the sample vaporize more reliable, reduces the thermal radiation generated by the vaporization chamber, and ensures that the temperature deviation in the column box is very small;

6. Intelligent fuzzy control rear door opening system, automatically track the temperature and dynamically adjust, the air valve Angle, even near the room temperature can also achieve precise temperature control;

7. Equipped with filling column column head inlet sample, glass lining inlet sample, with diaphragm cleaning, functional capillary shunt / no shunt into the sample device, and gas sample inlet can be installed;

8. High precision and dual stable gas path, and four detectors can be installed at the same time;

Temperature control index

1. Temperature control range: room temperature of 5℃ ~400℃ increment of 0.1℃

2. Temperature control accuracy: better than 0.1℃ of ±
