Product Feature 1. Large-screen LCD display, real-time display of various temperature and operating conditions, clear and intuitive content, and truly realize the man-machine dialogue.
2. Power-on self-test, wide-range self-diagnosis function, can accurately determine the fault location and alarm.
3. Six-channel independent temperature control (the vaporization chamber and capillary vaporization chamber can independently control the temperature), eight-step temperature program function.
4. Over-temperature protection function: if any channel exceeds the set temperature, the instrument will automatically power off and alarm.
5. The unique vertical heating device makes the sample vaporization more reliable, minimizes the heat radiation generated by the vaporization chamber, and ensures that the temperature deviation in the oven is extremely small.
6. The door opening system after the intelligent fuzzy control automatically tracks the temperature and dynamically adjusts the angle of the air door to truly achieve near room temperature operation.
7. Equipped with packed column stigma injection, glass lining injection, capillary split/splitless injection device with diaphragm cleaning function, and a gas sampler can be installed.
8. High-precision dual-stable gas circuit, three kinds of detectors can be installed at the same time. Technical Parameter
