Robinair has introduced new air conditioning (A/C) leak detectors that are compatible with nearly all refrigerants used today, including R1234-yf and R-134a. The leak detectors, LD3, LD5 and LD7, meet all industry standards and are now available in North America to help technicians find leaks faster. Robinair’s new leak detectors are made in the USA with globally sourced components.
