Product 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.
