The EX-TEC HS 680 is perfect for detecting leaks in underground natural gas pipelines. Its multi-array sensor suite includes infrared for pinpointing the exact location of leaks along the pipeline. This system avoids unnecessary and costly excavations. Its optional integrated ethane-C2H6 detector provides easy verification of whether the gas leaking from the underground is a natural gas produced from the pipeline or simply a naturally occurring biogas (i.e., marsh or swamp gas). Precision leak pinpointing is achieved using the optional oxygen-O2 sensor. The O2 sensor indicates the minimum O2 level while simultaneously measuring for the maximum methane-CH4 level. This "minimum" with its smaller diffusion area in conjunction with the maximum methane indication provides easy pinpointing of complex leaks.
