  • SF6 Gas Hazards and How to Avoid Them - WIKA blog

    The best way to avoid SF 6 gas hazards is to continually monitor gas-insulated equipment for both quantity (to detect leaks) and quality (for current gas conditions). Then, when the gas has dropped below a certain level of purity, technicians can clean it. Here are just a few of WIKA USA’s innovative SF 6 gas solutions for greater safety and efficiency:
