Bubble-up leak detector. RTU BU is a Bubble-up leak detector specifically designed to locate refrigerant leaks. Standard bubble-up leak detectors, designed for use with natural gas, are unsuitable: their lower viscosity means they will not cling to surfaces as effectively and can easily be blown off the pipework before the refrigerant leak is identified.
