SF6 Gas Analyzer with Vaisala 143 Sensor for Dew Point Measurement Range -80°C to +20°C and Modular Customization

The KS30-6 SF6 Gas Analyzer is a high-precision portable gas analysis instrument designed for comprehensive SF6 gas quality testing in GIS substations, circuit breakers and high-voltage electrical systems.

It integrates SF6 dew point measurement, SF6 purity analysis and SF6 decomposition gas detection into one compact intelligent platform, enabling fast and reliable gas condition evaluation during installation, commissioning and preventive maintenance.

The dew point measurement module is built on the KST-VII platform and uses an imported Vaisala 143 high-precision sensor, ensuring stable, accurate and long-term moisture measurement performance in SF6 gas environments.

With a modular design architecture, KS30-6 can be configured according to different testing requirements and is widely used in power utilities and GIS maintenance applications worldwide.
