A destructive coating Thickness Gauge is an instrument that measures the thickness of a coating by cutting or abrading a sample and is commonly used in research and quality control. The following are the selection points and precautions for destructive coating Thickness Gauges:
select points
Cutting method: Destructive coating Thickness Gauges usually have two methods: cutting and abrasion, and the appropriate method needs to be selected according to different experimental requirements.
Measuring range: Select the appropriate instrument according to the thickness range of the coating to be measured, usually different blades or grinding heads can be selected.
Accuracy requirements: Different applications require different accuracy requirements, usually you can choose instruments with different accuracy levels.
Material: Select the appropriate blade or grinding head according to the material of the coating to be tested.
Functional requirements: Select an instrument with functions such as automatic calculation and data storage as required.
Precautions
Before use, it is necessary to pre-treat and clean the blade or grinding head to avoid affecting the measurement accuracy due to impurities.
The sample needs to be fixed well during the measurement to avoid the influence of the movement and displacement of the sample on the measurement result.
During the measurement process, it is necessary to avoid excessive force on the blade or grinding head, so as not to affect the measurement results.
The sample needs to be cleaned after measurement to avoid contamination and damage to the sample.
Safety issues cannot be ignored during use to avoid injuries due to improper operation.
