The RLD400 Digital Refrigerant Leak Detector enables HVACR technicians and contractors to detect leaks of all common refrigerant gases, including many of the new ozone layer-friendly blends, with increased sensitivity, the company says. Using a true mechanical pump and a proprietary semiconductor sensor designed to last 10 years, the handheld instrument signals leak detection by beeping and flashing, and indicates the relative leak size.
