Nenvitech SF6-Air leak detection for transformers

Indirect leak detection solutions are rapidly expensive as they require one monitoring device per gas compartment. Furthermore, the pressure/density switches that are currently used to monitor the SF 6 gas compartment for safety consideration are lacking sensi-tivity for rapid leak detection. Direct detection is normally a preferred and more reliable
