EXF Coating Thickness GaugeNon magnetic coatings (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic metal substrates (such as steel, iron, alloys, and hard magnetic steel) and non-conductive coatings (such as enamel, rubber, paint, etc.) on non-magnetic metal substrates (such as copper, aluminum, zinc, tin, etc.) can be measured non destructively. The coating thickness gauge has the characteristics of small measurement error, high reliability, good stability, and easy operation. It is a testing instrument for controlling and ensuring product quality, and is widely used in manufacturing, metal processing, chemical industry, commercial inspection and other testing fields.
Measurement steps of EXF coating thickness gauge:
Marking: Use a marking pen to make a small colorimetric mark on the surface of the coating being measured.
Scratch: Hold the instrument with the blade facing down and the magnifying glass viewing hole facing forward, place the blade not far in front of the mark, and at this time, the two guide bolts and the blade are tightly attached to the surface of the coating. Apply light pressure to keep the blade straight across the mark and make sure that the coating contacts the substrate.
Numerical grid: Turn on the light bulb switch next to the magnifying glass sight hole, focus the magnifying glass on the scratch on the mark, adjust the focus knob at the bottom to find the focal length of *; Rotate the upper sight glass tube and slightly adjust the position of the instrument so that any long scale line overlaps with the scratch line of the paint mark. Then count the small scale grids from left to right until the second layer of paint or substrate, which is the total number of small grids for a single or multiple layers.
Retrieval: Multiply the total number of small cells by the corresponding coefficient according to different models to obtain the total thickness of each single or multiple layers of the coating.
The EXF coating thickness gauge adopts magnetic induction and eddy current technology for thickness measurement, and is an ultra small measuring instrument. It can measure the thickness of non-magnetic coatings (such as aluminum, chromium, copper, zinc, tin, enamel, rubber, plastic, paint, etc.) on magnetic metal substrates (such as steel, iron, alloys, and hard magnetic steel, etc.) without damage. It can also measure the thickness of non-conductive coatings (such as rubber, paint, plastic, anodized film, etc.) on non-magnetic metal substrates (such as copper, aluminum, zinc, tin, etc.).
Usage: It can be widely used in manufacturing, metal processing industry, chemical industry, inspection and other testing fields. Due to its small size and integrated probe, this instrument is particularly suitable for on-site engineering measurements; This instrument is sturdy, durable, versatile, and can be operated with one hand.
