LF-03-FR Portable SF6 Leak Detector is a high-sensitivity infrared SF6 quantitative leak detector specially designed for GIS inspection, SF6 circuit breaker maintenance and high-voltage switchgear leak testing.
The detector adopts imported NDIR infrared sensor technology, providing fast response, excellent stability and highly accurate quantitative SF6 leak detection performance.
With minimum detection sensitivity down to 0.1 ppm, LF-03-FR can rapidly identify micro SF6 leakage points in GIS equipment, substations and electrical power systems.
LF-03-FR is an upgraded model based on LF-01-FR and LF-02-FR platforms and can be used as an alternative to WIKA and DILO SF6 infrared leak detectors.
KSTONE is also one of the drafting organizations of Chinese National Standard GB/T11023-2018 for SF6 gas tightness testing of high-voltage switchgear equipment.
LF-03-FR SF6 leak detector provides ultra-high sensitivity with minimum detection limit up to 0.1 ppm for accurate quantitative SF6 leak analysis.
The detector adopts imported dual-beam NDIR infrared technology for stable and reliable SF6 gas leak detection.
Compact lightweight structure with flexible gooseneck probe design for easy operation inside switchgear cabinets and GIS systems.
Color touchscreen interface enables intuitive operation and real-time SF6 concentration monitoring.
When SF6 leakage exceeds preset value:
Built-in hooding algorithm supports quantitative SF6 leakage rate calculation for GIS equipment testing.
Rechargeable lithium battery supports more than 6 hours continuous operation.
