Product Description
GDSF-411WPD 3-in-1 SF6 Gas Analyzer is combined of SF6 humidity (dew point) test, SF6 purity test and SF6 gas decomposition product test. It integrates the functions that can only be achieved with three instruments in one instrument. One-time on-site measurement can complete the detection of all indexes, which greatly saves the gas in the equipment, at the same time reduces the workload of users and improves work efficiency.
Features
1. Zero-point automatic calibration, full curve tracking correction.
2. Protected gas chamber with patented technology, fast measurement speed. l
3. Easy to operate and easy to carry.
4. Good repeatability and fast response.
5. With temperature compensation function
6. AC and DC dual-use, built-in rechargeable lithium battery, automatic switching, overcharge and over discharge protection.
7. Automatic slope calibration.
8. Auto pump back function.
9. Big true-color touch screen, easy to operate.
10. Advanced probe protection.
11. Anti-pollution and anti-interference.
12. High sensitivity and good stability.
