Product Details
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.
