The 580951 features a long life solid electrolyte sensor technology that is designed to detect more current and difficult HCF refrigerants such as R-134a, R410a, R404a, R407c, and R507 in addition to all HCFC (R22) and CFC (R12) refrigerants including SNAP approved hydrocarbon blends.

The unique digital leak size indicator takes the guesswork out of whether or not to repair a small leak. The digital display is independent from the audio alarm and sensitivity level, allowing the precise pinpointing of the leak source.

The tester does not require rechargeable batteries. An optional detachable UV light will soon be available that clips on to the probe to allow both electronic or UV detection using the one tool. Full instructions and specifications are include with the tester.
