Portable SF6 Gas Analyzer With High-Accuracy Moisture Measurement And Modular Design For SF6 Dew Point And Purity Testing

The KS30-3 SF6 Gas Analyzer is a portable multi-functional testing instrument designed for comprehensive SF6 gas quality assessment in high-voltage electrical equipment.

The analyzer combines SF6 dew point measurement, SF6 purity analysis and SO2 decomposition gas detection in a single compact device, enabling maintenance engineers to quickly evaluate gas condition and insulation performance in GIS substations, circuit breakers and gas-insulated equipment.

Developed based on China's SF6 testing standards DL/T1366-2018 and DL/T1353-2024, the KS30-3 offers reliable performance, fast response and modular expandability for utility companies, power plants and electrical service providers.

• Simultaneous SF6 dew point, purity and SO2 analysis
• Portable field-ready design
• High-accuracy moisture measurement down to -80°C dew point
• Fast purity testing with response time ≤30 seconds
• Sensitive SO2 detection with 0.1 ppm resolution
• Built-in pressure measurement
• USB data storage and export function
• Rechargeable AC/DC dual power supply
• Modular design for customized configurations
• Suitable for GIS, switchgear and circuit breaker maintenance

• GIS (Gas Insulated Switchgear) maintenance
• SF6 circuit breaker inspection
• Electrical substation commissioning
• SF6 gas quality verification
• Preventive maintenance programs
• Power transmission and distribution systems
• High-voltage equipment testing
• Utility service and field engineering operations

Unlike single-function SF6 testing instruments, the KS30-3 provides three essential gas quality measurements in one device. Maintenance personnel can evaluate moisture content, gas purity and SO2 decomposition products during a single test procedure, significantly reducing testing time and improving maintenance efficiency.

The modular architecture also allows future upgrades according to customer requirements, making it a cost-effective solution for long-term SF6 asset management.
