Robinair ZX-1A Heated Pentode Refrigerant Leak Detector

The Robinair ZX-1A uses patented Heated Pentode® sensor technology to find refrigerant leaks faster and more accurately than conventional detectors. By directing you straight to the leak source and eliminating ambient false alarms, it reduces diagnostic time and closes service calls quicker — whether you're working on residential split systems or industrial refrigeration circuits.
