Features:

Xizi Energy’s SF₆ gas density gauge with dual alarm contacts delivers precise, temperature-compensated monitoring for SF₆ switchgear.
Featuring a three-color dial (red/yellow/green) for instant status checks and two independent micro switch sets (1~2, 3~4) for warning/blocking signals, it enables early leak detection and safety interlocks. Built with 304 stainless steel, it resists corrosion and vibration, maintaining accuracy (Class 1.6 at 20°C, Class 2.5 at -30~60°C) across harsh environments.
Compliant with IEC 60282, it is ideal for 12kV/24kV SF₆ RMUs, GIS, and industrial substations, ensuring reliable medium voltage grid safety.
