A/C Refrigerant Leak Detector

The Robinair LD5 Select Refrigerant Leak Detector features a new color graphic display that helps locate leaks using a unique bar graph mode to show the amount of refrigerant detected in the air and changes colors as it gets closer to the leak. The LD5 also uses an audible alarm to alert technicians of refrigerant leaks and an inspection light for searching in dark locations.

The LD5 is compatible with most commonly used refrigerants today including 1234-yf and R-134a and is equipped with a stable, long life sensor that will last up to 10 years. The LD5 meets all of the current industry leak detector standards and is covered by a 2-year warranty. Uses 4 AA batteries, included.
