Car Paint Meter for Detecting Automotive Paint Thickness
To evaluate the value of the used car, many car apprasiers will use car paint meter to test the used car paint thickness. Because it is difficult to identify the repaint and sheel metal, the car paint meter gives scienfitic measured data.
The Linshang Car Paint Meter LS220 has many functions, excellent workmanship, small size and low price. It is a necessary paint thickness measuring instrument for testing automotive paint thickness.
2. Car paint meter of magnetic and eddy current principles
Linshang auto paint meter is an coating thickness measuring instrument for testing the thickness of coatings on metal substrates. It is often used to test the paint thickness of automobiles. This instrument uses eddy current and Hall Effect principle. After the automatic measurement mode is turned on, the car paint meter automatically identifies the substrate material in which the coating is located and switches to the appropriate mode.
The magnetic auto paint meter use magnetic principle. It is suitable for measuring the paint thickness on magnetic metal substrate such as iron.
Magnetic measuring principle: The plating thickness is determined by the amount of magnetic flux that the probe passes through the non-ferromagnetic plating and flows into the ferromagnetic metal substrate. Magnetic induction plating thickness gauge is suitable for measuring non-magnetic metal platings on ferromagnetic metals such as steel, paints, varnishes, enamels, plastics, rubber coatings, chromium plating, zinc plating, cadmium plating, copper plating, etc.
The eddy current auto paint meter use eddy current principle. It is suitable for measuring the paint thickness on non magnetic metal substrate such as aluminum.
Eddy current measuring principle: Eddy currents are generated through a process called electromagnetic induction. When alternating current is applied to a conductor (such as copper wire), a magnetic field is generated in and around the conductor. The magnetic field expands as the alternating current rises to the maximum, and collapses as the current decreases to zero. If another electrical conductor is brought close to the changing magnetic field, a current will be induced in the second conductor. Eddy current is an induced current flowing in a circular path. Their name comes from "vortex". When conditions are right, a "vortex" is formed when liquid or gas flows in a circular path around an obstacle.
3. What are the characteristics of the car paint meter?
Many car paint meters on the market need to be calibrated on special standard plate before use. The calibration process will greatly affect the efficiency of instrument testing. However, Linshang automotive paint meter LS220 does not need to be calibrated. The instrument has tested a large number of standard films during the development process. The linearity of the instrument is very good. After purchasing LS220 car paint meter, the customer does not need to use another standard calibration to measure. It can be used for a long time after simple zero adjustment.
Rapid measurement, the probe is sensitive. The meter can complete a measurement in 0.5 seconds. Other car paint meters will take several times longer when measuring paint film thickness.
LS220 car paint meter has temperature compensation function, and the car paint meter uses digital signal to transmit data. These two functions make the instrument's sensor signal more stable and ensure the instrument's test accuracy in the case of large temperature changes.
Using Ruby probe: Linshang car paint meter has a strong resistance to corrosion and wear, long service life, and fair prices.
Only a single button, boot and zero adjustment are both on a button, the operation is very simple.
With small size, light weight, it can be operated with one hand and is easy to carry.
Of course, we have a variety of auto paint meters that can be used to test the coating thickness. For more product information, please refer to the "Coating Thickness Gauge Selection and FAQ”.
