Selection points of coating thickness gauge
Coating thickness gauge is a commonly used thickness gauge product, which uses electromagnetic induction method to measure the thickness of coating, mainly including continuous measurement mode (CONTINUE) and single measurement mode (SINGLE). How should users choose coating thickness gauge products? The following editor will introduce the key points of coating thickness gauge purchase in detail, hoping to help everyone.
Key Points for Choosing a Coating Thickness Gauge
1. Copper and chromium layers on plastic: It is recommended to use a coulometric thickness gauge (which will damage the coating) or an X-ray thickness gauge (non-destructive measurement). If the copper layer is 10m~200m, an eddy current method thickness gauge (non-destructive Measurement).
2. Galvanized layer on metal parts: For example, economical magnetic induction method thickness gauge (non-destructive measurement) should be used on the steel substrate. For other metal substrates, use a coulometric thickness gauge (which will destroy the coating) or an X-ray thickness gauge (non-destructive measurement).
3. The electrophoretic paint on the iron substrate should use an economical magnetic induction method thickness gauge (non-destructive measurement). For electrophoretic paint on other metal substrates, an economical eddy current thickness gauge (non-destructive measurement) should be used for the paint.
4. Dry film refers to the cured paint coating.
5. Refer to item 2 and item 1 for the chrome plating layer.
6. Only the chipping method (PIG, which will destroy the coating) is used for painting the interior and exterior parts of the car. The ultrasonic method (non-destructive measurement) can measure the coating above 10 microns, but sometimes it cannot be detected.
7. Price: 60,000 to 30,000 for magnetic induction method and eddy current method; 8,000 to 60,000 for coulometric method; 55,000 to 60,000 for ultrasonic method; 250,000 to 400,000 for X-ray thickness gauge.
