OverviewThe UHV-630 is a high-precision handheld SF6 gas leak detector designed to locate SF6 leaks accurately and support efficient maintenance of SF6-insulated equipment by combining multiple detection methods, real-time concentration monitoring, configurable alarms and data trend analysis.
Key features- Detection methods: pump-suction sampling combined with NDIR single-beam dual-wavelength infrared sensing for sensitive and stable detection with dynamic waveform display.
- Alarms and display: configurable audible and visual alarms with user-defined thresholds; color LCD menu interface and real-time waveform visualization.
- Signal processing: advanced digital processing with drift control and temperature compensation for improved anti-interference performance.
- Operational functions: full self-check (low battery, sensor fault, range exceedance), self-calibration and perpetual calendar for time-stamped records.
- Data and power: built-in data logging with waveform storage up to 20,000 records and a long-life lithium battery providing over 5 hours continuous operation.
- Design: compact, handheld form factor for field maintenance and rapid leak localization.
Applications- Maintenance and inspection of SF6-insulated switchgear, circuit breakers and high/extra-high-voltage equipment.
- On-site leak localization where SF6 loss can degrade arc-quenching performance or create oxygen-deficient zones.
