Portable Switchgear Gas Analyzer with NDIR Infrared Spectroscopy for Trace SF6 Detection

The KS30-H Environmentally Friendly Switchgear Gas Analyzer is a portable multi-gas testing instrument designed for modern dry air insulated switchgear, nitrogen insulated switchgear, and environmentally friendly medium-voltage and high-voltage equipment.

The analyzer is specifically developed to detect trace SF6 contamination, measure O₂ and N₂ concentration, and identify whether the switchgear is dry-air insulated or nitrogen-insulated based on gas composition analysis. An optional dew point and moisture measurement module enables comprehensive gas quality assessment for equipment commissioning, maintenance, acceptance testing, and environmental compliance verification.

As utilities and manufacturers transition from traditional SF6-insulated equipment to alternative insulating gases, the KS30-H provides a reliable solution for gas verification, contamination monitoring, and insulation condition assessment.

Utilizing advanced NDIR infrared spectroscopy technology, the analyzer accurately detects residual or trace SF6 concentrations in environmentally friendly switchgear systems.

• Detection range: 0-100 ppm
• Resolution: 0.1 ppm
• Fast response within 30 seconds
• Suitable for SF6 contamination verification

The instrument simultaneously measures nitrogen (N₂), oxygen (O₂), and trace SF6. By analyzing gas composition, the KS30-H can quickly determine whether the equipment uses dry air insulation, nitrogen insulation, mixed gas systems, or potential SF6 contamination.

An optional high-precision moisture module enables dew point measurement, micro-water analysis, insulation quality assessment, and moisture contamination monitoring.

• Lightweight 3.5 kg construction
• Rechargeable lithium battery
• AC/DC dual power supply
• Suitable for substation and field service applications

The analyzer delivers rapid measurement results, helping maintenance personnel reduce testing time and improve operational efficiency during commissioning and routine inspections.
