Product Description
SF6 Quantitative Leak Detector – 0.01ppm High Sensitivity for GIS & Switchgear
LF-1G
Product Introduction

The LF-1G is the upgraded LF-1D+ model, adopting radiation-free high-frequency magnetic field low-voltage ionization technology.

With an ultra-high sensitivity of 0.01ppm, the detector allows engineers to accurately identify extremely small leaks and locate leak points quickly.

The equipment is widely used by:

  • Power utilities
  • High voltage switchgear manufacturers
  • Substation maintenance service providers
  • Electrical testing laboratories

It is suitable for SF6 sealing detection and micro-leak positioning in GIS and high voltage switchgear equipment.

Key Features
Ultra-High Sensitivity (0.01ppm)

Detect extremely small SF6 leaks in sealed high-voltage equipment.

Quantitative Leak Detection

Real-time ppm concentration display allows engineers to evaluate leakage levels accurately.

Fast Response

Response time ≤1 second enables quick leak point localization.

Portable Field Operation

Compact design makes it ideal for substation inspection and field maintenance.

Durable Industrial Design

Metal chassis and cleanable air inlet ensure long service life in industrial environments.

Applications
GIS Leak Detection

Gas insulated switchgear uses SF6 as insulation gas.
Even very small leaks may affect equipment reliability.

The SF6 quantitative leak detector allows engineers to locate micro leaks in GIS equipment quickly.


High Voltage Switchgear Manufacturing

Switchgear manufacturers use leak detectors during factory testing to ensure equipment sealing performance.


Substation Maintenance

Power utilities use portable SF6 leak detectors during routine inspection of high-voltage equipment.

Why High Sensitivity Leak Detection Matters

SF6 gas is widely used as an insulation medium in high voltage equipment.

However, even small leaks may lead to:

  • Reduced insulation performance
  • Gas loss and maintenance costs
  • Environmental impact

High-sensitivity leak detection allows engineers to identify leakage at an early stage and maintain equipment reliability.

Customization Options

The detector can be customized according to customer requirements, including:

  • Different power supply standards
  • Probe hose length
  • Detection range configuration
  • Interface language options
