Measuring principle

518SThe paint film tester conforms to the standard wedge-cutting method, in which case the pattern is cut at a specified angle

The thickness of the coating can be calculated using a simple geometric relationship through the projected width of the cutting surface. 518SIn the measurement microscope, a series of concentric circles, measured using a measuring microscope can be measured by the diameter of the concentric differences, multiplied by a known factor can be calculated Out of film thickness.

measuring instrument

518SAll of the important components, drilling tools, measuring microscopes, sample lighting and batteries are housed in a sturdy little box that can be moved in a horizontal chute with a drill and microscope 518SThe drill bit is resiliently mounted in the chute so that it can be pressed against the specimen with minimal force and the drill bit is automatically activated. Can provide high-precision cutting angle to meet the different 4The measurement magnification of the measuring microscope is 50, Measurement scale there 100Line, so each measurement range can get one 1%Of the resolution 518SOn the panel of the paint tester, it can be set to continuous or intermittent lighting to extend battery life. 9VRechargeable batteries, chargers can also be used as electrical appliances 90°) The microscope is available 2Move the direction of the axis, and the scale can be rotated, so 518-SParticularly suitable for evaluating elliptical holes in surface samples.

Method of operation

use 518SThe thickness of the coating is very simple: the marker is used as a marker to place the instrument on the surface of the sample, and the drill bit is moved over the test point and the motor is lowered. The penetration coating reaches the substrate. The microscope to the top of the hole, the lights open, read the substrate and the comparison mark between the number of degrees, and then multiplied by a scale factor will be measured
