The Mark 9822 Helium Detector represents a breakthrough in portable leak pinpointing equipment for pressurized telephone cable systems. Mark Products has developed a rugged yet highly sensitive field unit with the speed of continuous sampling and the selectivity of a separate fast-sample batch mode. Using the continuous mode a technician can "survey" multiple manholes or along direct buried cable routes quickly and easily. In batch mode a separation column helps to distinguish helium from other background gases aiding in precise leak pinpointing. The Model 9822 has a wide range of sensitivity and will detect both small and large leaks.
