If gases escape through leaks in piping systems (e.g. untight screwed connections, corrosions and so on) ultrasonic noises are generated. By means of LD 400 even the smallest leakages which cannot be heard by the human ear and which are not visible due to their size can be detected even from distances of several meters. LD 400 transforms the inaudible signals into a frequency which can be identified. By means of the comfortable sound-proof headset these noises can be realized even in extremely noisy environments. The LD 400 leak detector is the advancement of the proven LD 300 and it convinces by its obviously refined sensor technology and its improved support in the tracing of leaks. By means of the integrated laser pointer which serves for target heading the leak can be localized more accurately. Annual energy costs caused by leakages LD 400 with focus tube and Applications focus tip for precise locating Leak detection in: • Compressed air lines, gas, vapor and vacuum plants • Refrigerating plants • Door seals

Due to a particularly designed acoustic trumpet a better focusing of the acoustic waves is achieved. This acoustic trumpet acts like a directional microphone while interfering ambient noises are cushioned and the accurate localization of the leakages is eased even in areas which are difficult to access. Due to the special design of the acoustic trumpet the use of the laser pointer is not obstructed. A handy ultrasonic transmitter is available for detecting leaks in depressurized systems. The transmitter is positioned in a way that the sound can access the piping system. The ultrasonic signal...
