LF-1D+ SF6 Quantitative Leak Detector - High-Precision & Fast-Response Leak Detection Expert

Key Features

  • Ultra-Sensitive Detection:0.01ppm minimum detection limit (range: 0.01–1000ppm) via low-voltage ionization technology, outperforming infrared dual-wave detectors in sensitivity.
  • Rapid Response:≤1 second reaction time to 100ppm SF6, enabling fast leakage point localization in high-voltage switchgear and power equipment.
  • Intuitive Operation:LCD digital display with real-time concentration readings and variable buzzer alerts for easy leak assessment.

Industry Credibility

As the drafter of GB/T11023-2018 national standard, this detector ensures industrial-grade reliability for cost-effective, low-maintenance SF6 leak testing in electrical equipment. Ideal for utilities, manufacturing, and energy sectors.

Optimization Notes

  • The best tool for finding leaks.
  • Data-Driven Emphasis:Bold key metrics (0.01ppm, ≤1s) to highlight technical superiority.
  • SEO-Friendly Keywords:Incorporates "SF6 leak detector", "high-voltage switchgear", and "national standard" naturally.
  • Application Focus:Links technical features directly to utility and industrial use cases.
