Key Points for Purchasing Coating Thickness Gauge Solutions to Common Problems of Thickness Gauge
Layer thickness gauge is a commonly used thickness gauge product, which uses electromagnetic induction method to measure the thickness of the 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 Purchasing 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, an 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 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.
Reasons why the indicated value of the ultrasonic thickness gauge is too large or small compared with the design value
The digital display ultrasonic thickness gauge is a relatively precise instrument, and it needs to be used with caution, because a small mistake will not only cause errors in the measurement data, but also damage the instrument to a certain extent. The following is an introduction to the precautions for the use of ultrasonic thickness gauge probes:
1. The probe of the ultrasonic thickness gauge cannot be pulled, thrown or dropped violently.
2. When using, when inserting and pulling out the two cables of the probe, you should hold the metal part of the cable to prevent the probe from breaking.
3. During on-site use, the probe should try to avoid grinding on rough and uneven surfaces.
4. After the probe is used, the coupling agent on the probe should be wiped off in time to keep the probe clean.
