The KS30-J9 SF6/N2 Gas Mixture Analyzer is a high-precision analytical instrument based on chilled mirror dew point technology and modular gas analysis design. It is specifically developed for modern gas-insulated power systems using SF6/N2 mixed gases, providing comprehensive measurement of gas composition and insulation condition.
The system is capable of measuring:
With high stability and laboratory-grade accuracy, it is widely used in GIS substations, high-voltage switchgear, and gas quality monitoring applications.
Direct optical condensation measurement ensures ultra-high accuracy and long-term stability without sensor drift.
Simultaneous measurement of SF6, N2, moisture, and decomposition gases in one system.
SF6 accuracy up to ±0.05% and N2 accuracy up to ±0.03%.
Monitors SO₂, H₂S, and CO to evaluate insulation degradation and fault conditions.
Flexible structure for maintenance, calibration, and future expansion.
Designed for outdoor substation environments with temperature compensation and anti-interference capability.
Unlike traditional capacitive humidity sensors, chilled mirror technology measures dew point temperature by directly detecting condensation on a cooled mirror surface.
This ensures:
It is widely regarded as the most accurate method for dew point measurement in high-end gas analysis systems.
