Leaks in large systems often occur far from the leak detector. By utilizing modern wireless technology, leak testing hard-to-reach locations is now much easier, and can be performed at much greater distances of up to 100 meters. In addition to the visual bar graph of the leak rate, the remote control has a speaker that provides a variable tone indicating the trend and relative size of the leak. All the major functions of the leak detector are at your fingertips, giving you a truly portable leak detection solution.
