Product Introduction
With China's substation voltage levels continuously increasing, SF6 high-voltage circuit breakers are witnessing approximately 15% annual growth in the power sector, having become the predominant insulation and arc-quenching medium for high-voltage, ultra-high-voltage and UHV switchgear. However, as most SF6 switches are installed indoors, gas leakage not only creates oxygen-deficient zones endangering personnel but also severely compromises arc-extinguishing performance. The high-precision handheld SF6 gas leak detector provides reliable maintenance solutions by accurately locating leaks through multiple detection methods including SF6 concentration monitoring, audible/visual alarms and data trend analysis, effectively eliminating potential safety hazards while ensuring equipment reliability.
Advantages
The SF6 gas leak detector incorporates cutting-edge pump suction and NDIR single-beam dual-wavelength infrared technology for highly sensitive, precise and stable detection. It features advanced digital processing with drift control and temperature compensation circuits to ensure superior anti-interference capability.
For user convenience, it offers full self-check functions (low battery, sensor fault, range exceedance) and a color LCD with Chinese menu interface. Detection data is displayed in real-time with dynamic waveform analysis, while audible/visual alarms trigger at preset thresholds.
Additional highlights include:
Self-calibration function for maintained accuracy
Long-lasting lithium battery (5+ hours continuous operation)
Built-in data logging (20,000 records with waveform storage)
Compact handheld design for portability
Perpetual calendar clock for time-stamped records
