“Best tool for the job!”

In over 25 years of business, I've
seen units with suspected refrigerant
leaks but were too small to find.
With the Amprobe RLD-1 refrigerant
leak detector I can take the guess
work out of finding and repairing a
refrigerant leak. I recommend that if
you are in the HVAC business this is
a must have for every tool bag!”
