Portable Electromagnetic Wave Guide Detector

Performance characters:
→ used for specific cable, steel, rebar and other long-distance detection (for buried steel and cable);
→ with low attenuation, long detection distance, the farthest detection distance is up to 300m;
→ with intuitive image, easy to identify and understand;
→ with long single detection distance (more than 50m, up to 300m), high detection efficiency and directional emission (positive, negative and two-way), no coupling agent needed;
→ DSP high-speed firmware processing technology processor and FPGA do parallel processing to improve the signal processing capability and speed;
→ with controllable band digital filter denoising function and the denoising process does not affect the wave height and accuracy;
→ use industry standard case to ensure that the instrument's anti-interference and stability and adapt to different environment conditions;
→use AC / DC power supply with flexible power supply, over-voltage, over-current and overload protection;
→ Instrument and probe connection cable use custom double-layer shielding structure, effectively shielding interference source.
