The LF-302 represents an upgraded iteration of the LF-301, tailored for on-site SF6 leak detection with a telescopic handle design for enhanced mobility. Unlike the LF-303 (which features an oil-free pump), the LF-302 incorporates a double-stage oil-lubricated vacuum pump, delivering robust performance for industrial applications. Leveraging low-voltage ionization in a high-frequency magnetic field, it achieves 0.01ppm sensitivity, supported by set-value alarms (buzzer and concentration visual cues).
