Measuring devices for leak detection and calculation

Leakages are the reason for the biggest waste of energy in compressed air systems. Several studies show that 30% of the cost of compressed air can be saved by eliminating leakages. Therefore, it is a must to detect and eliminate leakages frequently. Our LD-Series will give you all the function needed to detect leakages and measure the consequences in terms of energy consumption and wasted money.

Typical applications of our measuring instruments in this section are leakage detection in compressed air systems and leak testing of unpressurized systems. 

You can also find more information on how to use our leakage devices and associated software correctly in our "Video Tutorials" section.

LD 500/510 - Leak detector with camera

Due to the integrated camera and the available accessories our starter kit for leak detection enables reliable leak detection as well as compressed air leakage calculation and reporting according to ISO 50001.

The set includes a robust impact-proof transportation case which contains all necessary components and accessories.


Which leak detection device to choose?

While LD 400 is reliable in detecting leaks the LD500 is also able to calculate the costs those leaks will cause over time. The user gets a review about the actual state of the tested system and about the estimated potential cost savings. If you are not sure which instrument is for you please contact our experts. We help you to find the leak detection device that fits the application needs in your compressed air or gas environment.

The following table gives you an idea of how much the actual potential savings are that you can realize by detecting leaks in compressed air systems. 

Leakage Size Air loss Energy loss Costs
