Detect leaks in your compressed air system to save money

The new leak meters Leak Check Pro 1/Pro 2 with integrated camera and leakage calculation are ideal measuring instruments which help to find and document even smallest leakages (0.1 l/min corresponds to approx. 1 € per year) from far away. It is ideal for detecting leaks at:

  • Compressed air, gas, steam and vacuum systems
  • Steam traps
  • Seals
  • Refrigeration systems

The noise-proof headset enables the leak detection also in extremely loud environments. The ambient noise will be faded out and the leakage (inaudible ultrasonic sound) will be transformed to an audible signal.

Leakage files stored in Leak Check Pro are exported to a USB stick which is used for the software-generated report. The Leak Check Pro meets the requirements of Class I “Standard Test Method for Leaks with ultrasound” (ASTM Int. - E1002-5)

Leak Detectors

Leaks in compressed air systems may be tiny, but they can have huge effect on a compressor’s energy consumption. In fact, by eliminating leaks, energy costs can be reduced by up to 30%. To make sure that no air and energy is wasted, a leak detector helps find and eliminate these leaks.
