Description: Very often leaks in large systems occur far from the leak detector. Wired hand-held remote controls have sought to address this problem, but impedance and the cumbersome nature of long cables are often limiting factors. For many applications these traditional wired remotes provide little benefit. The first wireless remote control for a helium mass spectrometer leak detector has been introduced. By utilising 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 metres. Applications in large systems in which two technicians were previously required can now be performed by one technician, thereby reducing labour costs. All the major functions of the leak detector are now at users' fingertips, giving users a truly portable leak detection solution. 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. The wireless remote can operate for a full 8-hour shift, or longer, on four AA batteries and conforms to ISM band, 2.4 GHz FHSS standards. Applications include vacuum furnaces, glass coaters, roll coaters, E-beam welders, beam lines/accelerators as well as semiconductor process tools.
