Wireless robust test rod for acoustic water leak detection. The AquaTest T10 water leak detector test rod brings innovative technology and ergonomic design. Its strength lies in the pre-location of water leaks in pipe networks. The AquaTest T10 is the first Sewerin test rod that without a receiver.
The headphones are activated by a special sensor area. The clear display on the handle graphically shows noises. In the product variant with the SDR radio module, the test rod can be used with radio headphones. This means no more cables to get in the way.

Leak Pre-location
The high-quality microphone technology of the AquaTest T10 detects even the smallest water leak noises. Extension rods attach to the AquaTest to reach deeper pipes and valves. Individual optimization of acoustic results is assisted by the option of selecting one of eight different frequency bands. Eight background noise filters aide leak detection by blocking interfering noises. In operation the flow noises at the fittings can be sampled by simply placing a thumb on the sensor area. This avoids the irritation caused by operation noises in the headphones while listening. The AquaTest T10 leak detection equipment displays the current and previous minimum water leak noise levels plus the current noise intensity. The minimum noise levels are shown as numeric values; the actual noise intensity is displayed as a bar graph helping to pinpoint the leak.

Non-metallic (plastic) pipe location

Applying sounds to the pipes using the Combiphon, Knocker, Stopper or RD500 allows location of pipes by following sounds from the pipe with the AquaTest T10. the water pinpointing leaks and acoustic pipe location pre-located leaks can also be pinpointed with the AquaTest T10.

Water leaks under slabs and streets

The probe tip is replaced with a tripod foot (optional) when listening through hard surfaces. 

Kit Includes:
• AquaTest T10
• Headphones
• Probe tip
• Chargers
• Transport bag

Optional accessories
• Tripod
• Extensions for the probe tip

Water Leak Detectors

Sewerin Aquaphon Digital

• Extremely sensitive wind protected microphone with insulated shell to block exterior noises.
• Easily set the lower and upper noise filters in 50 Hz steps for precise control.
• Maximum noise limiter prevents damage to hearing and the equipment
• Displays the minimum or maximum level of the previous and current reading. The minimum level is the most useful since the maximum levels are background noises.
• Identifies the minimum level at each location
• Automatically scans the frequencies to set the noise filters.
• Weatherproof case
• Rechargeable batteries with charging docking bay in case.

The principle --of the water leak detectors:
When a pressurized underground water pipe develops a leak, water flows through it into the surrounding soil at high speed. In consequence:

• The pipeline material vibrates at the water leak. This vibration transmits through the pipe where it can be detected at water valves, hydrants, water meters and other remote contact points on the water pipe. The sensitive headphones, microphone and amplifier with noise filters helps the user determine the water leak location.
• The water leak jets and pipes induce vibration in the soil which transmits to the surface, where it can be picked up as ground-borne noise.

Water leak noise is transmitted over long distances in metallic pipes and detected very effectively with the special microphone within the test rod.

Water Leak Detection with the ground microphone

Water leak noises are not transmitted well by non-metallic pipe materials. Taking readings at the valves is not enough: the sections between valves must also be checked with a ground microphone for utility water leaks..

The AQUAPHON® EW receiver displays the water leak noise level both graphically and with a number including displaying the level of the last reading for comparison. The graphical bar display across the top also shows the lowest current sound levels and indicates the lowest sound level during each reading. This is a primary indicator of water leak location since the background noises vary, but the water leak noises are constant.  Finding the location where the minimum sound level is the highest is an important key to water leak detection.
