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

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

Key Features
Ultra-High Sensitivity (0.01ppm)

The detector can identify extremely small SF6 leaks, enabling accurate micro leak detection in sealed electrical equipment.

Fast Response

The instrument responds within 1 second, allowing engineers to quickly locate leakage points during inspection.

Quantitative Detection

Real-time digital display of SF6 concentration in ppm provides accurate leak evaluation.

Portable Field Operation

Compact and lightweight design makes the device suitable for substation inspection and field maintenance.

Durable & Low Maintenance

No vulnerable components and long service life reduce maintenance costs.

Product Parameters
Item Technical Parameters

Input Power 220V±22V 50Hz±2Hz
Rated Power 250W
Continuous Working Time ≤8 hours
Base Value Range (SF6-free environment) 27-30 (standard base value: 28)
Calibration Requirement Calibrate base value to 27-30 in SF6-free environment before use
Special Accessories Standard filter element protective cover, special vacuum pump oil, special key
Product Limitations
  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.
Applicable Scenarios
  • 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

High Voltage Switchgear Manufacturing

Switchgear manufacturers use leak detectors during factory testing to ensure equipment gas tightness and product quality.

Substation Maintenance

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

Why High Sensitivity Leak Detection Is Important

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.

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
