Request Information
If pressurized gases escape through leaks in pipe systems (e.g. leaky screw connections, pipe corrosion etc.), noises are generated in the ultrasonic range. With the LD 450, 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. The LD 450 transforms the ultrasound, which is inaudible to humans, into audible frequencies. With the comfortable, sound-proof headset, these noises can be heard even in extremely noisy environments. The LD 450 leak detector is a further improvement on the proven predecessor models (LD 300 and LD 400) and impresses with its significantly refined sensor technology and its improved support in the tracing of leaks. With the help of the integrated laser pointer, which serves for target heading, the leak can be localized more accurately.

Additional Information

Additional Information

 N/A Through the use of a specially designed acoustic trumpet, a better focusing of the sound waves is achieved. This acoustic trumpet acts like a directional microphone, focusing ultrasonic waves to improve acoustic performance. Due to the special design of the acoustic trum-pet, the use of the laser pointer is not hindered.

Leak test: An easy to handle ultrasonic transmitter is available for detecting leaks in systems that are not under pressure. The transmitter is positioned so that the sound can enter the pipe system.

The ultrasonic signal penetrates the smallest openings, which can then be detected with the LD 450.

LD 450 is available either as standalone device or in a complete set. The set includes a robust impact-resistant transport case which contains all necessary components and accessories.
