Portable infrared SF6 leak detector with dual-wavelength NDIR technology for GIS inspection, SF6 switchgear maintenance and quantitative SF6 leak detection.
Product Overview
LF-02-FR Portable SF6 Leak Detector is a compact and lightweight quantitative SF6 leak detector designed for field inspection and leak detection of GIS switchgear, ring main units, SF6 circuit breakers and gas insulated electrical equipment.
The detector adopts advanced dual-wavelength NDIR (non-dispersive infrared) sensing technology , providing stable performance, fast response and accurate quantitative SF6 leak detection.
With maximum sensitivity up to 0.1 ppm, LF-02-FR can quickly identify micro SF6 leakage points during substation maintenance and electrical equipment inspection.
Unlike traditional thermal conductivity leak detectors, high-concentration SF6 gas does not affect the infrared sensor or cause performance degradation. , ensuring long-term stability and reliable operation.
The detector can also detect other halogen gases qualitatively.
Our company is one of the drafting units of Chinese national standard: GB/T11023-2018 High Voltage Switchgear -- SF6 Gas Sealing Test Method.
Key Features
High-Sensitivity SF6 Leak Detection with sensitivity as low as 0.1 ppm
Dual-Wavelength NDIR Infrared Technology for improved detection stability and accuracy
Audible Alarm Function with frequency changes according to SF6 concentration level
Portable Handheld Design ideal for GIS inspection and outdoor maintenance work
Long Battery Runtime supporting more than 8 hours continuous operation
Manual Pump Control to extend diaphragm pump service life
PM1.0 -2.5 Particle Filter Protection System for improved sensor lifespan and detection stability
