Made to last: The ILD-300 is a robust and firm leak detector, easy to grab, and feels comfortable on the palm of your hand, the unit is impact resistant and the sensor life is up to 10 years. 

Top-of-the-line sensitivity: If you want to find leaks faster, Elitech's ILD-300 can sniff out <4 g/yr. That is 30 times more sensitive than the soap bubbles method. The sensitivity can be adjusted in three levels low, medium, and high. The unit also counts with a 14.37" probe which will allow users to identify leaks in just a few seconds.

No False triggerUnlike many other leak detectors, the ILD-300 will not be influenced by oil or moisture. The unit counts with a buzzer alarm which is proportional to the intensity of leakage, it also shows the intensity of the leakage on a bar graph. 

Intuitive operation: The ILD-300 has simple operation settings in order to facilitate everyday work. The unit counts with a large LCD screen and numerical readings, the bright colors will help you to know exactly what you are seeing. It holds a charge for up to 6hours and be used while charging.
