LD 400

LD 400

Ultrasonic Leak Detector

Leak detector LD 400 is the successor of the proven LD 300 and convinces by its 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, vacuum plants or refrigeration plants 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 detected even in extremely noisy environments.
