High-precision Coating Thickness Gauge

overview

It is possible to measure coatings and plating quickly, without damage, and with precision. It can be used both in the laboratory and in the engineering field. By adapting to different probes, a wide range of measurement needs can also be accommodated. This instrument is widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and other testing fields. It is an instrument required for the material protection profession. This instrument complies with the following standards: GB/T 4956-1985 Measurement of the thickness of non-magnetic overlay on magnetic metal substrates, magnetic method, GB/T 4957-1985 Thickness measurement of non-conductive overlay on non-magnetic metal substrates, eddy current method. JB/T 8393-1996 Magnetic and eddy current cladding Thickness Gauge JJG 889-95 JJG818-93

Features

● Full Chinese menu interface operation, simple and convenient;

● This instrument adopts two thickness measurement methods, magnetic and eddy current, which can nondestructively measure magnetic metal substrates (such as steel, iron, alloy and

  Hard magnetic steel, etc.), the thickness of the non-magnetic overlay (such as zinc, aluminum, chromium, copper, rubber, paint, etc.) and the non-magnetic metal base

  The thickness of the non-conductive overlay on the body (e.g., copper, aluminum, zinc, tin, etc.) (e.g., rubber, paint, plastic, anodized film, etc.).

● There are two measurement methods: continuous measurement mode (CONTINUE) and single measurement mode (SINGLE);

● It has two Operating Modes: direct mode (DIRECT) and group mode (A-B);

● There are five statistics: MEAN, MAX, MIN, NO.,

  standard deviation (S.DEV);

●A variety of calibration methods: the instrument can be calibrated by one test piece calibration and two test piece calibration methods, and the systematic error of the instrument can be corrected by five test piece calibration;

● With storage function: it can store 4 types of workpieces, 26 groups of each type of workpiece, 15 measured values in each group, a total of 1560 measured values;

● It has the function of deleting: deleting a single suspicious data that appears in the measurement, and also deleting all the data in the storage area in order to carry out new measurements;

● Set the limit: the measured value outside the limit can be automatically alarmed; 

●It has the function of communicating with the PC: the measured value and statistical value can be transmitted to the PC for further processing of the data;

● There is a beep prompt during the operation;

● High-brightness LED backlight display, which is convenient for use in dark environments.

● There are two shutdown modes: manual shutdown mode and automatic shutdown mode

Principle

This instrument adopts two thickness measurement methods, magnetic and eddy current, which can non-destructively measure the thickness of the non-magnetic coating layer (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) on the magnetic metal matrix (such as steel, iron, alloy and hard magnetic steel, etc.) and the thickness of the non-conductive coating layer (such as enamel, rubber, paint, plastic, etc.) on the non-magnetic metal matrix (such as copper, aluminum, zinc, tin, etc.).

Magnetic method (F-probe)

When the probe is in contact with the coating layer, the probe and the magnetic metal substrate form a closed magnetic circuit, due to the presence of the non-magnetic coating layer, the magnetic circuit magnetic resistance changes, and the thickness of the coating layer can be derived by measuring its change.

Eddy current method (N-type probe)

The high-frequency alternating current is used to generate an electromagnetic field in the coil, and when the probe is in contact with the coating layer, eddy currents are generated on the metal substrate, and a feedback effect is generated on the coil in the probe, and the thickness of the coating layer can be derived by measuring the magnitude of the feedback action.
