INTRODUCTION
The ATD-3700 features a long life heated sensor technology that is
designed to detect the more current and difficult HFC refrigerants
such as R-134a in addition to all HCFC (R22) and CFC (R12)
refrigerants including SNAP approved hydrocarbon blends.
The ATD-3700’s 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 ATD-3700 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 with one tool.
