  • Product Overview

    Mitech MET Series Portable Eddy Current Flaw Detector,also known as digital electromagnetic detecor,based on the principle of electromagnetic induction,can detect various metal parts surface or near surface defects with high-speed. It uses advanced DSP digital processing and FPGA technology innovation designed, with 5.7-inch TFT LCD screen, can clearly display the detection data.The product has high sensitivity, stable performance, multi-channel simultaneous detection and intelligent data analysis, can be equipped with intelligent probe, can also be customized probe according to customer needs , with extended magnetic memory, coating thickness, conductivity measurement and other practical Features. It is widely used in all kinds of metal pipe rods, auto parts, bearings, oil casing, oil control rods, ring metal parts in non-destructive testing and scientific research and other areas of higher education research.It is the necessary professional precision testing equipment to improve production efficiency, saving production costs. 

    Function & application

    l All kinds of metal pipe rod wire high-speed non-destructive testing (according to user needs customized package of non-

    destructive testing solutions);

    l Quality quality links of bearing, ring, auto parts and other metal parts manufacturing quality control links;

    l Colleges and universities learning, scientific research and other fields;

    Working Principle

    The eddy current detection technique is based on the principle of electromagnetic induction, and the excitation signal is loaded into the probe coil. When the probe is close to the metal surface, the alternating magnetic field around the coil will generate the induced current on the metal surface.For flat metal, the flow of induced current is a coil concentric circular, shaped like a vortex, named as the eddy current.The size, phase and flow pattern of the eddy current are affected by the conductivity of the specimen.The eddy current also produces a magnetic field that in turn causes the impedance of the detection coil to change.So when the conductor surface or near the surface of the defect or the measurement of metal materials change, the intensity and distribution of eddy currents will be affected by changes in the impact,Which in turn causes a change in the detection coil voltage and impedance.Eddy current testing is based on this change, the indirect feedback of the existence of defects within the conductor and the performance of metal materials have changed.

    standards.

    Operating Method and Attentions

    Instrument Maintenance

    l Read the manual carefully before using the instrument. Learn the operation steps and attentions; To avoid damage 

    or personal safety accidents due to improper operation.

    l The instrument for precision measuring instruments, when using,it should be taken lightly to avoid the human factors 

    caused by the sharp impact and fall, resulting in equipment damage, Proposed use of protective cover;

    l Probe cable is a wearing element, please avoid distorting pressure. When plugging, it is recommended in the shutdown 

    state, and is strictly forced to drag, so as not to pull off the damage;

    l Key operation, you should not be too much force, and stained with too much oil and muddy water fingers should not 

    touch the instrument;

    l Sensor is a key component of picking up the signal, precision sensitive, more fragile, special attention to prevent bruises, 

    proper use;

    l Long time idle, should be charged regularly (about once a month);

    l According to the prompts, when the battery capacity is nearly exhausted, it should be charged in time to avoid affecting 

    the use;

    l Don’t disassemblethe instrument without authorization, maintenance related matters, please contact MITECH after-sale 

    service department, 4000600280.
