Description
SF6 Leak Detector – NDIR Gas Sensor for GIS and Switchgear
LF-1D+

The SF6 Leak Detector is a high-precision gas detection instrument designed for SF6 gas leakage detection in high voltage electrical equipment such as GIS, circuit breakers and gas insulated switchgear.

Using advanced NDIR infrared gas sensing technology, the device provides fast and accurate detection of SF6 gas concentrations, helping engineers quickly locate leakage points during equipment manufacturing, installation and maintenance.

The detector is widely used by:

  • Power utilities
  • High voltage switchgear manufacturers
  • GIS maintenance service companies
  • Electrical testing laboratories
Key Features
High Sensitivity Leak Detection

Detect extremely small SF6 gas leaks to ensure the safe operation of high-voltage equipment.

NDIR Infrared Gas Sensor

Advanced non-dispersive infrared technology ensures high measurement accuracy and strong anti-interference capability.

Fast Response

Real-time detection allows engineers to quickly locate leakage points during inspection.

Portable Design

Compact and lightweight structure suitable for substation and field maintenance work.

Digital Display

Real-time concentration display with intuitive operation for engineers.

Explosion-Proof Design

Suitable for industrial environments requiring safe gas detection.

Core Advantages
High-Sensitivity & Accurate Detection

Adopts advanced low-voltage ionization technology combined with a high-frequency magnetic field, enabling ultra-precise capture of trace SF6 gas leaks with a minimum detectable concentration of 0.01ppm and a wide detection range of 0.01ppm-1000ppm. This core technical advantage delivers significantly superior detection performance compared with conventional leak detectors based on the infrared dual-wave principle.

Ultra-Fast Response & Efficient Localization

Boasts an ultra-rapid response speed of ≤1 second in a 100ppm SF6 gas environment. The instant detection capability allows for quick and accurate localization of leakage points on-site, effectively eliminating time-consuming repeated detection and greatly improving overall SF6 leak inspection efficiency for high-voltage equipment.

Intelligent Digital Display & Intuitive Operation

Equipped with a high-definition LCD screen that real-time displays the actual SF6 leakage concentration value, with numerical changes that directly correspond to concentration fluctuations for clear and intuitive data reading. The device is complemented by an intelligent buzzer with variable frequency prompts—buzzer frequency changes with the increase of gas concentration, providing dual audio-visual prompts for operators. This humanized design simplifies on-site operation and reduces misjudgment risks, suitable for various complex industrial detection scenarios.

Enterprise Credibility & Product Compliance

As the drafting unit of China's national standard GB/T11023-2018 High Voltage Switchgear - SF6 Gas Sealing Test Method, we have core technical discourse power and industry-leading R&D capabilities in the field of SF6 gas detection. The LF-1D+ SF6 Quantitative Leak Detector is fully designed and manufactured in accordance with strict industrial-grade detection standards, with product performance and technical parameters fully compliant with national standard requirements.
