Portable Quantitative SF6 Leak Detector Gas Sensor 0.01ppm Sensitivity With Telescopic Handle LF-303
Product Overview
The LF-303 distinguishes itself with an oil-free vacuum pump. Engineered for precision SF6 leak detection, its telescopic handle design ensures mobility, while the low-voltage ionization technology delivers 0.01ppm sensitivity. The system includes audible-visual alarms and a fault self-check function for user-friendly operation.
