The ultrasonic thickness gauge and coating thickness gauge independently developed by PIEZOHANNAS Co., Ltd. have passed ISO9000 and CMC certification, and the product series are available in many varieties and specifications. The products are exported to many countries and regions and are one of the

The high frequency AC signal generates an electromagnetic field in the probe coil, and a vortex is formed therein when the probe is close to the conductor. The closer the probe is to the conductive to substrate, the larger the eddy current and the greater the reflection impedance. This feedback acti

Principle of magnetic suction measurement and thickness gaugeThe amount of suction between the permanent magnet (probe) and the magnetically permeable steel is proportional to the distance between the two, which is the thickness of the coating thickness measurement gauge. Using this principle to mak

Ultra-thin materialWith any ultrasonic thickness gauge, when the thickness of the material is being tested below the probe's lower limit of use, measurement errors will result, and if necessary, the minimum limit thickness can be measured by the test block comparison method.When it is measuring ultr

A protective layer that protects the surface of the material, such as coatings, coatings, overlays, chemically formed films, etc., which is referred to as coating in some national and international standards.Coating thickness measurement gauge has become an important part of the processing industry

Several methods in measurement1—Single measurement method: measurement at one point2—Double measurement method: Perform two measurements with a probe at one point. The probe crosstalk spacers should be perpendicular to each other in both measurements. Selecting the minimum value in the reading as th

The principle of ultrasonic thickness gauge measurement is similar to the principle of light wave measurement. The ultrasonic pulse emitted by the probe reaches the back-test object and propagates through the object. When it reaches the material interface, it is reflected back to the probe. The thic
