SL-2098-type buried pipe outside the anti-corrosion layer of the detector in the case does not open the casing, can easily and accurately detect underground metal pipe location, direction, depth, coating damage, the number of damage points, The distance between the damaged points, the size of the point of breakage and other functions. Mainly used in accordance with SYJN4029-88 and GJJ33089 standards acceptance of the pipeline; the completion of the new pipeline laying acceptance; according to safety regulations on the pipeline regular inspection to determine the cathodic protection ; To locate the branch on the main line; to test the old pipeline to determine whether the need for overhaul of the pipe; excavation of the construction section before the underground pipeline distribution inspection to prevent the destruction of underground oil, gas, water, electricity Pipeline.

'Features'
★ The new digital filtering technology, you can set the scope of the leak, automatically record the number of leaks, and accurately show the distance between the leak;
★ With a variety of detection methods, and automatic conversion. Transmitter battery voltage and automatic shutdown before the issue to the receiver prompt signal, the value is automatically saved when turned off.
★ Can automatically measure the resistance of the pipeline to the ground, the output signal modulation high frequency alarm signal, strong anti-interference ability. Transmitter output power can be automatically adjusted with the detection distance increases, the transmitter is automatically shut down detection to improve the instrument detection Effect, to extend the battery life and life.

'Detection principle and method'
Detecting the direction and buried depth of the principle and method: to the underground pipeline to send a specific high-frequency modulated signal by detecting the magnetic field of underground pipes to determine the location of the underground pipeline, direction and depth.
There are peak method and zero value method.
Detection principle and method:
To the underground pipeline to send a specific high-frequency modulation signal in the underground pipeline anti-corrosion layer at the break point and the earth to form a loop, and to the ground radiation, radiation damage in the top of the signal is strong, according to this principle to find the pipeline corrosion point.
The use of 'human capacitance method' is to do with the human body sensor leak detector components, when the leak detector went near the leak, the leak detector began to react when the leak came to the top, the speaker of the sound , Showing a large value, so as to accurately find the leakage point.
