G640 uses quantum well infrared detector, which can accurately find SF6INH3 leakage point through thermal imaging. This portable thermal camera can detect leaks from a safe distance, therefore it can greatly ensure the safety of operators. In addition, it can also track some harmful gases to make contributions to environment.
