SF6 Gas Analysis  Testing | Detailed introduction of technical principles

SF6 Gas Analysis and Testing, SF6 Gas Analyzer, Micro-water Decomposition Product Parameters (-80-+20℃):
H2S: 1-200 PPmv
SO2: 1-100 PPmv
CO: 1-500 PPmv

The MS-408 SF₆ Gas Analyzer integrates an SF₆ micro-water analyzer, an SF₆ purity analyzer, and an SF₆ decomposition product analyzer into one instrument. Functions that previously required three separate instruments are now concentrated in one unit. A single on-site measurement can complete the detection of all three indicators, significantly reducing gas consumption by 2/3 per measurement, while also reducing user workload and improving work efficiency.

Product Features:

1. Dew point measurement uses a reliable Finnish Vaisala sensor, ensuring an annual drift of less than ±1℃.

2. Purity measurement uses an advanced NDIR sensor, guaranteeing a full-range accuracy of ±0.5%FS.

3. Patented protective gas chamber technology ensures fast measurement speed.

4. Full-channel polymer material design ensures no moisture or other gas adhering to the walls, guaranteeing testing speed.

5. Oil-free stainless steel regulating valve ensures accurate measurement values.

6. Modular chassis configuration allows users to easily combine related instruments and accessories.

7. Easy to pack and carry, providing a more convenient user experience.

8. High-power lithium battery system supports both AC and DC power supply.

9. No need for on-site AC power supply; lithium battery power allows for continuous operation for over 8 hours without external power.

10. Electromagnetic interference protection circuit design ensures product reliability. 11. Good repeatability and fast response speed

12. Built-in temperature compensation function

13. AC/DC dual-use, built-in rechargeable lithium battery, automatic switching, overcharge and over-discharge protection

14. Automatic slope calibration, can automatically calibrate the sensor in self-test mode, ensuring the annual drift rate of the whole machine is less than 1%

15. 5-inch true color touch screen, simple and easy to operate, displays data such as trace water, purity, decomposition products, and flow rate on the same screen.

16. Advanced probe protection function

17. Anti-pollution, anti-interference, high sensitivity, good stability,
