Pipe detector SR-24

Professional pipe detector with GPS and Bluetooth

Innovative technology for effective measuring operations:

The SeekTech SR-24 is an easy-to-handle precise pipe detector with GPS and Bluetooth for the quick localization of underground or concealed supply lines.

Even difficult pipe detections can be performed successfully using the SR-24. Owing to multi-directional antennas, guiding arrows and an easily legible map display this pipe detector leads you precisely to the pipe in question in next to no time.

Be it water or gas pipes, power or telecommunications lines, thanks to the special 3D antenna technology inductive and passive pipe detections can be performed with the SR-24 from every position and direction – regardless of the user’s location. This is an invaluable benefit especially in case of obstructions or on the road. Even in case of a great number of subterranean supply lines in a confined space, the target line and its branch lines can be accurately distinguished from neighbouring lines by means of multiple active and advanced passive search modes with manifold predefined or individually adjustable search frequencies.

Including smartphone app for simple pipe mapping in real time

The pipes detected with the SR-24 can easily be mapped on your smartphone or tablet using RIDGIDtrax. The app is available free of charge for Android and iOS devices. Once connected to the SR-24 via Bluetooth, your mobile device indicates the GPS position and depth of the respective line. It is possible to highlight the type of line (water, gas, power) or to display several pipes on the same map. The completed map can be saved and viewed in the app or exported as KMZ file to be used with other GIS programmes.

The optimum operation mode for every location task

The SR-24 detects electromagnetic fields emanated from underground objects. For this purpose, the detector can be used in different operating modes:

Active signal, for instance via SeekTech transmitter ST-510
Active signal

Active pipe detection

In this mode, energy is supplied for the supply line intended for routing and localization via a transmitter and the line is then actively located by use of the chosen frequency.

Passive signal
Passive signal

Passive pipe detection

In passive mode, the device looks for electromagnetic noise in subterranean supply lines. Electrical appliances radiate these signals to a certain degree off to power lines to which they are connected or else subterranean supply lines act as antennas for high-performance and low-frequency radio transmissions and reverberate these signals.

These current and radio frequencies can be passively received at an appropriate field strength an so enable the location of the corresponding supply line.

Probe mode

For the detection of a probe’s signal in non-conducting pipes, cables or tunnels, which cannot be located in any other way.

The camera system SeeSnake can f.i. be used for pipe inspection, there the FleXmitter transmitter integrated in the camera head can be located in its exact position using the SR-24. This combination is an especially effective and precise method for leak detection!

All information quickly at one glance

Position, direction and depth of the line is displayed by the SR-24 in real time.

The intelligent technology of the SR-24 dynamically adapts all displayed information depending on the search mode and level of proximity to the line, for instance as zoom indication when approaching the target or to indicate the position of the transmitter in probe mode.

Without having to avert one’s gaze from the display or to put the device down, settings can be adjusted during a measurement via single-handed operation on the clearly structured control panel.

SeekTech transmitter for active pipe detection

For active pipe detection combine the pipe detector SR-24 with our SeekTech transmitters

The signals may be transferred to underground metal pipes or cables by means of a direct terminal connection, by induction using a transmitter coil or optionally with an inductive signal clamp. If required, the cables can be extended using two supply lines of 15 m length.

Both transmitters come with an induction-dependent acoustic signal transmitter, a power saving function with automatic switch-off and an LCD display with automatic background illumination for the status indication.

The ST-33Q+ impresses not only with its unsurpassed induction performance and high degree of flexibility due to freely selectable frequencies of up to 93 kHz with a direct connection, it can also be configured directly from the SR-24 via Bluetooth from afar.
