AquaPhon A50 Basic Kit

The reasonable entry-level model for professional acoustic water leak detection: compact – on-hand – efficient

The AQUAPHON® system provides professional, electro-acoustic water leak detection. The A 50 receiver and various microphones make the pre-location and pinpointing of leaks possible. When both microphone and headphones are attached the device boasts impressively high reproduction quality. The display helps by visualizing the noises to provide reliable, differentiated evaluations. With a fully charged battery the A 50 receiver is ready for use for an entire work week. Light, handy, small – the receiver is cleverly compact and easy to carry. When the A 50 with SDR radio module (Sewerin Digital Radio) is used and the F8 wireless headphones are connected, there are no cables to affect the sound quality or restrict your movement. Thanks to adjustable filters, frequency ranges can be individually adjusted to your hearing and the impact of interference noise can be minimized. The AQUAPHON® system featuring the A 50 receiver is a reasonable entry-level system for professional electro-acoustic water leak detection.
