LEEB Leeb231 eddy Current Coating Thickness Gauge Measurement range 0~1250μm

Leeb231

Coating Thickness Gauge

Measurement range 0~1250μm, support continuous measurement and single Measurement mode, with statistical function, Measurement accuracy +/- 3%.

Overview

The eddy current measurement method enables non-destructive detection of the thickness of non-conductive insulating overlays on non-magnetic metal substrates (e.g. rubber, plastics, paints, oxide films, etc.) on non-magnetic metal substrates.

This instrument can be used in electroplating, anti-corrosion, chemical industry, automobile, shipbuilding, light industry, commodity inspection and other testing fields. It can be used both in the laboratory and in the engineering field. It is an important instrument in the inspection industry.

Features

● There are two measurement methods: continuous measurement and single measurement;

● It has two Operating Modes: direct and group;

● It has automatic statistical functions: average value (MEAN), maximum value (MAX), minimum value (MIN), number of tests (NO.), standard deviation (S.DEV);

● The instrument can be calibrated by using two methods: single-point calibration and two-point calibration, and the systematic error of the probe can be corrected by the basic calibration method;

● Storage function: 4 calibration workpieces can be saved. 26 groups of each category, 15 in each group, a total of 1560 measured values;

● Delete function: delete a single suspicious data that appears in the measurement, and also delete the data in the storage area to make a new measurement;

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

● It has the function of power supply under-Voltage indication, and there is a beep prompt during operation, and the automatic shutdown mode.

● Metal shell: The fuselage is made of aviation aluminum metal shell, which has low anti-interference wear.

Principle

● This instrument adopts the measurement principle of eddy current, which can measure the thickness of non-conductive covering layer (such as enamel, rubber, paint, plastic, etc.) on non-magnetic metal substrates (such as copper, aluminum, zinc, tin, etc.).

A. Eddy current method (N-type probe): the use of high-frequency alternating current in the coil to generate an electromagnetic field, when the probe and the overlay contact, the metal matrix produces eddy current, and the coil in the probe has a feedback effect, and the thickness of the covering layer can be derived by measuring the size of the feedback effect.
