Coating Thickness Gauge Buying Tips
Buying a coating thickness gauge is mainly selected through the following steps:
1: Determine the data to be measured as the thickness of the coating on the workpiece;
2: Make sure that the base material of the measured workpiece is metal;
3: Determine which metal the workpiece base material is:
(1) Take a magnet close to the workpiece, the magnetic metal (such as iron, etc.) can be attracted
(2) Non-magnetic metals (such as aluminum, copper, etc.) cannot be absorbed;
4: Confirm the coating:
(1) Non-metallic coatings (such as paint, powder, etc.);
(2) Non-magnetic metal coatings (such as galvanized, tinned, etc.);
5: Optional equipment:
(1) Requirements for the American L170 Coating Thickness Gauge:
①Substrate: Magnetic metal substrate (such as iron, etc.)
②Coating:
1) Non-metallic coating (such as paint, powder, etc.)
2) Non-magnetic metal coating (such as galvanized, tinned, etc.);
(2) Requirements for L180 Thickness Gauge of LEE Eddy Current Thickness Gauge in the United States:
①Substrate: non-magnetic metal substrate (such as aluminum, copper, zinc, etc.)
②Coating: non-metallic coating (such as paint, powder, etc.);
(3) Requirements for L200 L200 LEE Dual-function Coating Thickness Gauge:
① Substrate:
1) Magnetic metal substrates (such as iron, steel, etc.)
2) Non-magnetic metal substrates (such as aluminum, copper, zinc, etc.)
② Coating:
1) Non-metallic coating (such as paint, powder, etc.);
2) Non-magnetic metal coating (such as galvanized, tinned, etc.);
Summary: For non-metallic coatings (such as paint, oxide film, etc.) and non-magnetic metal (such as: aluminum, copper, etc.) coatings on magnetic metals (such as iron, steel, etc.) ;For non-metallic coatings (such as paint, oxide film, etc.) on non-magnetic metals (such as copper, aluminum, zinc, etc.), using the principle of eddy current technology, the American LEE coating thickness gauge has dual-function applications, which can automatically identify the bottom material.
