G7-SF6 Sulfur Hexafluoride NDIR Infrared Gas Sensor
Model: G7-SF6
Purpose-built for SF6 leak detection: 0-1000 ppm (extendable to 2000/3000 ppm), ≤±2%FS
The G7-SF6 is a Yixin NDIR (Non-Dispersive Infrared) sensor purpose-built for sulfur hexafluoride leak detection. It offers a 0-1000 ppm range (extendable to 2000/3000 ppm), accuracy of ≤±2%FS, 1 ppm resolution and T90 < 25 s (free diffusion). Strong selectivity to SF6 with no interference from water vapor, alcohol or CO2; temperature-compensated, long-life and maintenance-free. It outputs fault readings during warm-up or in condensing conditions to prevent false alarms. Compact in size with UART (TTL level) digital output and an analog output option, it plugs quickly into existing SF6 leak-detection and monitoring systems for electrical equipment, substations and switchgear.
