Coating Thickness Gauge Product Introduction
product description:
This thickness gauge is used to measure the thickness of electroplated layers or coatings on metal surfaces. Specifically, it can measure the thickness of non-magnetic coatings (such as chromium/paint/ceramics, etc.) on the surface of steel/iron and other magnetic materials. It can also measure copper/aluminum, etc. Coating thickness on the surface of non-magnetic materials (such as paint, etc.). This instrument has a built-in precision probe, which
Automatically detect substrate properties and detect coating thickness through electromagnetic induction and eddy current effects.
Application areas:
This instrument can measure coating and plating thickness without damage, quickly and accurately. It is widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and other testing fields. It is an essential instrument for material surface treatment engineering. It can work stably in laboratories, workshops and outdoors.
Measurement principle:
This instrument uses two principles: electromagnetic induction and eddy current effect. Can be used losslessly
Measurement of non-magnetic coatings on magnetic metal substrates (such as steel, iron and their alloys)
The thickness of the layer (such as paint, plastic, copper, chromium, zinc, etc.), and non-magnetic
Non-conductive coatings on metal substrates (such as copper, aluminum, zinc, tin, etc.)
Thickness (oxide film, plastic, paint, etc.).
The F-type probe applies the principle of magnetic induction: when the probe is in contact with the coated magnetic substrate
When in close contact, the probe and the magnetic substrate form a closed magnetic circuit, and the coating thickness
Corresponding to the magnetic circuit reluctance, measurement can be achieved by detecting changes in reluctance
The purpose of this cladding thickness.
The N-type probe applies the principle of eddy current effect: when the probe and the coating are non-magnetic,
When the metal base material is in close contact, the probe causes the base material to generate eddy currents, and the eddy currents cause
The feedback effect of the head is corresponding to the thickness of the coating. By detecting this feedback
The quantity achieves the purpose of measuring the thickness of the coating.
Instrument usage:
When using this type of instrument for the first time, please read carefully the above information that may affect the measurement accuracy.
Description of factors.
1. Open the battery cover, insert 2 AAA/1.5V batteries, and cover it again;
2. Prepare parts to be tested;
3. Place the instrument in an open space, at least 5 cm away from any metal, and press the on/off key to turn it on. When the instrument is turned on, it will automatically calibrate and display 5-4-3-2-1 and then enter the test mode.
4. Press the units key to select the desired unit; press the MODE key to select the desired measurement mode. SNG represents single-point mode (measure one point at a time), CON represents rapid continuous mode (high-efficiency rapid continuous);
5. Start measuring. In SNG single-point mode, quickly bring the probe into vertical contact and lightly press it against the test piece. A beep will sound and the screen will display the measurement value. Before the next measurement, the probe must be at least 5 cm away from the test piece, with a time interval of at least 1 second. ;CON in fast continuous mode, the probe contacts vertically and lightly presses on the object to be tested, the screen displays the measurement value, and the measurement point can be changed at will to quickly complete the next measurement;
6． The system automatically detects the metal properties of the specimen. Fe is displayed on the upper left side of the screen, which indicates that the base material is a magnetic material, which may be steel or iron, etc.; NF is displayed on the upper left side of the screen, which indicates that the base material is a non-magnetic material, which may be aluminum/aluminum alloy/copper, etc. ;
7． Shut down. Press the power button to shut down; the system has an automatic shutdown function, 15
If there is no operation for several minutes, it will automatically shut down;
Care and maintenance:
Users should avoid using the instrument under excessively harsh conditions such as collision, heavy dust, high temperature, humidity, strong magnetic field, etc., otherwise the instrument will be damaged. If the measurement value deviates greatly during use of the instrument, please first check whether the battery power is low and try to turn it on again. If still to no avail, try restoring to factory settings.
If the above method still cannot eliminate the fault, please contact the dealer in time. Please disassemble and assemble the machine by yourself in a hurry, otherwise the warranty service will be affected.
