Product Description
The Best Tool For Finding Leaks, With Fast Response And Sensitivity Up To 0.01ppm, Used By Thousands Of Factory Customers In China LF-1D+
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.
