The SF6 Quantitative Leak Detector is a high-precision instrument designed for micro leak detection of SF6 gas in high voltage electrical equipment such as GIS, circuit breakers and gas-insulated switchgear.
With an ultra-high detection sensitivity of 0.01ppm, the detector allows engineers to accurately locate even extremely small leaks and perform precise leak rate evaluation.
The equipment is widely used in:
Power grid utilities
High voltage switchgear manufacturers
GIS maintenance service providers
Electrical testing laboratories
The detector can identify extremely small SF6 leaks, enabling accurate micro leak detection in sealed electrical equipment.
The instrument responds within 1 second, allowing engineers to quickly locate leakage points during inspection.
Real-time digital display of SF6 concentration in ppm provides accurate leak evaluation.
Compact and lightweight design makes the device suitable for substation inspection and field maintenance.
No vulnerable components and long service life reduce maintenance costs.

Switchgear manufacturers use leak detectors during factory testing to ensure equipment gas tightness and product quality.
Power utilities use portable SF6 leak detectors during routine inspection of high voltage equipment.
SF6 gas is widely used in high-voltage equipment due to its excellent insulation properties.
However, even small leaks can lead to:
Reduced insulation performance
Gas loss and maintenance costs
Environmental impact
A 0.01ppm sensitivity detector allows engineers to identify leaks early and maintain equipment reliability.
The detector can be customized according to customer requirements, including:
Different power supply standards
Probe hose length
Detection range configuration
Interface language options
