The SF ₆ gas analyzer integrates SF ₆ micro water analyzer, SF ₆ purity analyzer, and SF ₆ decomposition product analyzer into one instrument, consolidating functions that originally required three instruments. One on-site measurement can complete the detection of three indicators, greatly saving gas in the equipment. One measurement saves 2/3 of gas usage, while reducing the workload of users and improving work efficiency.
Product features:
1. The dew point adopts reliable Finnish Vaisala sensors to ensure that the annual drift is less than ± 1 ℃
2. The purity adopts advanced NDIR sensors, which can ensure a full range accuracy of ± 0.5% FS
3. Using patented technology to protect the gas chamber, with fast measurement speed
4. Full channel polymer material design ensures no water or other gas wall hanging phenomenon, ensuring testing speed.
5. Adopting oil-free stainless steel regulating valve to ensure the accuracy of detection values.
6. The modular chassis configuration scheme allows users to easily combine related instruments and accessories.
7. Realize overall packaging and portability, providing users with a more relaxed user experience.
8. The high-power lithium battery power system can achieve dual power supply of AC and DC.
9. No on-site communication power is required, and lithium battery power can work continuously for more than 8 hours without the need for an external power source.
10. Anti electromagnetic interference circuit design ensures the reliability of the product.
11. Good repeatability and fast response speed
12. Equipped with temperature compensation function
13. AC/DC dual-use, built-in rechargeable lithium battery, automatic switching, overcharge and over discharge protection
14. Slope automatic calibration, which can automatically calibrate the sensor under self checking conditions, ensuring that the annual drift rate of the whole machine is less than 1%
15. 5-inch true color touch screen, simple and easy to operate, displaying micro water, purity, decomposition products, flow rate and other data on the same interface.
16. Advanced probe protection function
17. Anti pollution, anti-interference, high sensitivity, and good stability
