The visual leak size indicators consisting of 7 high brightness LED’s begin to light up as you approach the leak. The more LED’s on, the larger the leak.

The audible-leak indicator has a computer-like beeping sound, which increases in speed as you approach leaks.

The reset switch makes leak detection very precise and efficient.

Once the 5750A is turned on, the sensitivity is at its highest. If the unit starts to beep rapidly before the leak is found, just press the reset button. This will automatically recalibrate the leak detector’s sensitivity to the ambient atmosphere surrounding the tip. This feature allow you to “home-in” and track down the leak.
