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.

1. Low-Temperature Restriction: Prohibited to start below 0℃; special low-temperature model LF-1G(DW) is required for low-temperature scenarios, incurring additional costs.
2. Tedious Startup: Must check and fill special vacuum pump oil before startup; 20 minutes preheating is needed for the vacuum pump at 0-5℃.
3. Partial Accessories Without Warranty: Chassis, hoses, casters, detector and its protective cover are not covered by warranty, on-site wear needs self-replacement.
4. High Precision Requirements: Precision instrument requiring special personnel for storage and use in dry and clean environment; air inlet blockage or sealing ring aging will affect detection accuracy.
5. Vacuum Pump Misuse Risk: Damage caused by oil shortage or non-special oil filling is deemed improper use and not covered by warranty, operation must follow specifications strictly.

• SF6 gas sealing detection and leak point positioning of high-voltage switchgear and GIS combined electrical appliances
• Quantitative detection of SF6 micro/slow leaks in power substations and grid operation & maintenance sites
• Factory detection of SF6 sealing performance for power equipment manufacturers
• Industrial-grade SF6 leak detection complying with GB/T11023-2018 national standard

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

For complete SF6 gas handling solutions, we also provide:

• SF6 Gas Recovery Unit

• SF6 Gas Analyzer

• SF6 Gas Filling Equipment

• SF6 Vacuum Pumping Systems

1. Warranty Period: 1-year free warranty under normal use from purchase date, or 12 months from delivery date (whichever comes first).
2. Warranty Exclusion: Vacuum pump damage caused by oil shortage or non-special oil filling is not covered.
3. Non-Warranty Parts: Chassis, hoses, casters, detector and its protective cover.
4. Maintenance Requirement: A copy of warranty card and purchase certificate is required for maintenance within the warranty period.
5. Service Support: National Service Hotline: 400-000-2589; Technical Consultation: 021-50912468 / 021-50726919.
