s 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 LD 400 even the smallest leakages in compressed air lines, gas, vapour and vacuum plants or refrigeration plants can be detected even from distances of several meters.
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 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.
