HL7000 Digital Water Leak Detector
The HL7000 Pro Kit comes in a black SebaKMT charging case with a color touch screen HLE 7000 Hydrolux Receiver, belt clip, CS-7 carrying handle, PAM-W-7 windproof ground microphone, PAM-CORR-2 wired contact microphone with Magnet adapter, wireless headphones, lithium-ion rechargeable batteries and integrated GPS with audio mapping and ambient noise reduction.
Additional sensors and microphones are available for various conditions such as the H2 tracer gas sensor, heavy duty contact microphone and foot traverse. Replacement parts are also available.

In a damaged pipe, the escaping water causes two kinds of noise, which spread in different ways. The Hydrolux HL 7000 makes these two noises visible and audible for you:
1. The water that is escaping directly at the leak location generates noise which is transmitted through the ground to the surface. With the aid of the ground microphone, the Hydrolux picks up the noise and graphically displays the volume and the frequency spectrum.
2. Inside the pipe, the escaping water generates a pressure wave. You can hear this pressure wave as leakage noise with the Hydrolux and an attached sensor rod microphone, even at remote contact points of the pipe (valves, hydrants, house connections etc.).
The main constituent of these applications is an intuitive operating unit. All of the relevant menu items and measured data are clearly displayed on its high-resolution 4.3" touch color display. Extremely light but robust, the operating unit can be used in different ways: carried on the strap, fixed in place on the sensor rod or attached to pants or a belt using a clip. Work assignments lasting more than 10 hours are no problem thanks to the powerful lithium-ion rechargeable batteries.
The Bluetooth® capable, wind-protected piezoelectric ground microphone with integrated preamplification clearly picks up extremely low leakage frequencies on soft materials such as PVC or PE, and also high frequencies on steel or cast iron pipes.
Each part of the HL 7000 equipment has its own place in the charging and transport case. All chargeable components such as the operating unit, the sensor rod and the Bluetooth® headphones can be charged together in the case thanks to pre-installed charging cables.
Sometimes the acoustic methods are not sufficient for precise leak locating. In these cases, the HL 7000 has the option of attaching a trace gas sensor. This is quick and uncomplicated thanks to 360° sensor recording, automatic sensor detection and the Bluetooth® connection.
Simply fit the trace gas sensor to the sensor rod and locate the hydrogen-nitrogen mixture on the surface As well as the noise or trace gas sensor, you can also use the wired universal microphone. This can be directly connected to the HL 7000 operating unit. You can therefore conveniently “listen inside the pipe” in order to distinguish between leakage noise and potential interference.
