Overview

GAOTek Eddy Current Conductivity Meter is a professional device used to precisely measure the thermal performance, conductivity, and purity of the material. This conductivity meter uses 60 kHz to inspirit, matching the aviation industry standards, with dually interpreted data in %IACS or MS/m units. The device is incredibly compact, can be handheld and carried with ease. GAOTek Eddy Current Conductivity Meter comes with a high storage capacity of up to 1000 measurements alongside a premium property battery with extended battery life. The product has been designed with attention to portability and increased usage–the probe can be replaced manually and the 240×320 pixel LCD-TFT has in-built two languages, backlight and large typeface for measurements in not well-illuminated conditions. All those features above others make this current conductivity meter perfect for industry professionals and specialists. The GAOTek Eddy Current Conductivity Meter can be used to test the material’s purity, resistivity, and thermal performance.

Features

• The meter uses 60 kHz (aviation industry standard) to inspirit, and the testing data can be read in two kinds of unit: %IACS or MS/m.
• It can store 1000 measurement data.
• Its big typeface, the backlight illumination designs are advantageous for users to take the testing data even in low light conditions.
• The design of the meter is more advantages: the user can replace the probe in the outdoor do not need to return to the company to adjust the probe into matching the meter.
• Two kinds of operating languages satisfy different national demand.
• It uses the high property battery to make sure it keeps more running time, and because of its mini-size, it is easy to carry and to grasp hold.

Additional Informational

Introduction:
GAOTek-ECT-102 is a kind of eddy current electrical conductivity meter, which is designed for quick & convenient measurement of material property, such as material separate quality control material state check and so on. It uses the electromagnetism testing principle. Testing objects focus on non-ferromagnetic material.

Principles:
Eddy current exam is an NDT method established on the basis of electromagnetic induction principle; it is suitable for the conductive materials. Put the conductor in the alternating magnetic field, if inductive current exists, namely eddy current. On account of the change of each conductor’s own factors (for example conductivity, magnetic conductivity, shape, size, and flaw, etc.), will cause the change of the current, so we can use this phenomenon to judge the conductor’s character or state and whether flaw exists.
Eddy current test is to put the conductor close to the alternating current coil, the coil establishes the alternating magnetic field, this alternating magnetic field transits the conductor, and has the electromagnetic induction with it, establishes eddy current in the conductor. The current in the conductor also can produce its own magnetic field and can change the alternating magnetic field to be strong or weak, then causes the change of the voltage and R resistance. Therefore if the conductor’s surface or the near-surface has flaw or the metal material changes, the intensity and the distribution of the eddy current will also change, so as the change of the voltage and R resistance, according to this change, the eddy current may indirectly know about the flaw in the conductor and whether the performance of the metal material changed.

Functions and Operating Instructions:
Switch:
Under the off condition, press key , enter the test screen.
Press the Function key, enter the function surface.
Under the on condition, press for 3 seconds close the tester.

Calibration:
Please to calibrate before using the instrument every time and warm boot for five minutes before calibration.
Under the test screen, press the Function key（Fun）to move the red cursor under function ”Cal”, then press key (Enter), the screen will show as following:

Put the probe in the air for 3 seconds( far from the magnetic materials), and press key (Enter) to complete the calibration in air(this moment, please make the probe remained in situ for 3 seconds), then start to calibrate the NO.1 standard block, screen will show as following:

Make a full contact between the probe and NO.1 standard block(the low value one—Aluminum block) for 3 seconds, and then press key (Enter) to complete the calibration of NO.1 standard block (this moment, please make the probe remained in situ for 3 seconds), then start to calibrate the NO.2 standard block, screen will show as following:

Make a full contact between the probe and the NO.2 standard block（(the high value one— Copper block)for 3 seconds, and then press key (Enter) to complete the calibration of NO.2 standard block (this moment, please make the probe remained in situ for 3 seconds), then the calibration is OK, the system will automatically return to test interface.
