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.

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

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

Response time ≤1 second enables quick leak point localization.

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

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

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.

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

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

Engineers and maintenance teams working with HV switchgear and GIS equipment often search for reliable alternatives to well-known brands such as:

• DILO SF6 leak detector
• WIKA SF6 leak detector
• USON SF6 leak detector

The KSTONE SF6 Quantitative Leak Detector provides a cost-effective and high-performance solution designed for professional gas leak detection in power utilities and switchgear manufacturing.
