characteristic of Eddy current thickness tester DMC-211

Digital display of readings, reading

Most films on metal (oxide film on aluminum, plating and coating of zinc and chrome on iron), most metal films on nonmetal (plating on plastic etc) Nondestructive measurement in a short time (within 1 second), perfect for 100% inspection.

Easy operation by using a PC

Using a PC makes it easy to perform calibration and measurement operations. Various measurement modes can be selected, and measurement of small parts such as screw heads and wires and die casting products is easy.

Incorporates [Auto Import] mode

In the "Auto-capture" mode, you can automatically capture measured values simply by placing the probe on the object and releasing it.

A lot of characteristic curve (calibration curve) memory

70 automatically stored characteristic curves (calibration curves) are stored as standard. Special materials, etc. can be newly created and input with characteristic curves (calibration curves) if there is a standard plate.

Corporate information channel registration function

You can register the company name, part number, and lot number for each channel.
Total number of channels: 40 channels

equipped with statistical processing function

Measurement data can be saved for each channel, and statistical items can be set later for statistical processing.

Measurement unit

Measurement unit is mm, & m; m, mil, MI, & Aring;
The unit can be changed at any time, and the measured value is converted automatically.

Measurement principle

Measurement principle   When the probe (probe coil) with high frequency current is brought close to the metal, an eddy current is generated in the metal surface. The eddy current is affected by the strength, frequency, conductivity of the metal, thickness, shape, etc. of the high frequency magnetic field, and the penetration depth and its size differ.
And since the eddy current flows so as to cancel the high frequency magnetic field of the probe, the high frequency resistance value of the probe changes.Since the magnitude of the change in high frequency resistance is generally not proportional to the film thickness value, it is converted to a film thickness value in light of the internal or user-created characteristic curve (calibration curve), and the personal computer screen is displayed.
