Product Description
Portable Infrared SF6 Leak Detector for GIS & Electrical Systems
The SMART-200-FR portable infrared SF6 leak detector is a high-precision handheld instrument designed for detecting sulfur hexafluoride (SF6) gas leakage in high-voltage electrical systems.
SF6 is widely used in GIS (Gas Insulated Switchgear) and circuit breakers due to its excellent insulation properties. However, even small leaks can lead to performance degradation and environmental concerns. The SMART-200-FR is developed to provide reliable and fast leak detection in field environments.
Unlike traditional corona-based or chemical detection methods, this device uses infrared sensing technology, which provides higher stability, longer sensor lifespan, and better resistance to environmental interference.
It is suitable for both routine maintenance and emergency inspection scenarios in power systems.
How Infrared SF6 Detection Works
The SMART-200-FR uses infrared absorption detection principles to identify SF6 gas concentration changes in the air.
SF6 molecules absorb infrared light at specific wavelengths. The sensor measures the variation in infrared absorption and converts it into a readable leak signal.
Key advantages of infrared detection:
  • Non-contact measurement principle
  • Stable long-term calibration
  • No chemical consumables required
  • Less affected by humidity and temperature changes
  • Suitable for continuous industrial use
This makes the device ideal for high-voltage substations and outdoor inspection environments.
Key Features
High Sensitivity Detection (<4 g/year)
The SMART-200-FR can detect extremely small SF6 leaks, making it suitable for precision GIS inspection and preventive maintenance programs.
Three-Level Sensitivity Adjustment (L / M / H)
Operators can adjust detection sensitivity depending on environment conditions, improving usability in both noisy and controlled environments.
TFT LCD Visual Interface
A high-resolution TFT screen provides real-time leak indication, battery status, and system diagnostics for easier field operation.
Flexible Probe Design
The adjustable probe allows access to narrow spaces such as GIS cabinet joints, cable connection points, valve and flange areas.
Rechargeable Lithium Battery System
3.7V 3000mAh battery providing up to 6 hours continuous operation with fast charging in approximately 4 hours. Suitable for full-day field inspection tasks.
Intelligent Alarm System
Audible alarm for leak detection, peak leak recording function, sensor fault detection, and battery low warning.
Safety & Energy Efficiency Design
Automatic shutdown after 10 minutes idle, hardware power cut-off system, buzzer ON/OFF control, and earphone output for noisy industrial areas.
