Hand-held coating Thickness Gauge is a portable device used to measure the thickness of metal and non-metal coatings, usually used in on-site inspection and quality control. Here are some key points and considerations when choosing a handheld coating Thickness Gauge:
1. Measuring range: When choosing a hand-held coating Thickness Gauge, the instrument should be selected according to the coating thickness range to be measured. Generally, the measurement range of the instrument should be able to meet the application requirements, and at the same time, do not over-purchase a measurement range higher than the requirement, so as to avoid unnecessary cost waste.
2. Measurement accuracy: Accuracy is an important indicator to measure the performance of the hand-held coating Thickness Gauge. When choosing a handheld coating Thickness Gauge, you should choose an instrument with sufficient precision to ensure the reliability and accuracy of the measurement results.
3. Measuring principle: The measuring principles of hand-held coating Thickness Gauges are usually divided into various types, such as magnetic induction, eddy current, X-ray, etc. When selecting an instrument, the appropriate measurement principle should be selected according to the application requirements.
4. Coating type: Different types of coatings have different requirements for the selection of measurement principles and instruments. For example, the magnetic induction technique is suitable for the measurement of metallic coatings, while the eddy current technique is suitable for the measurement of non-metallic coatings.
5. Use environment: Hand-held coating Thickness Gauges are usually used in different environments, such as in the laboratory, workshop, field or outdoors. Therefore, when choosing a handheld coating Thickness Gauge, the use environment should be considered to choose a suitable model.
Precautions:
1. When using a hand-held coating Thickness Gauge, follow the instruction manual, and perform calibration and maintenance as required.
2. Before measuring, the measuring surface should be cleaned to ensure the measurement accuracy.
3. When using the handheld coating Thickness Gauge in different environments, attention should be paid to the influence of temperature and humidity on the measurement, and correction should be made.
4. For different types of coating measuring instruments, appropriate calibration standards should be selected, and calibrated and maintained as required.
5. Pay attention to the working time of the instrument, and replace the battery in time to ensure accurate measurement.
