The dual-purpose film thickness meter is a device suitable for both metallic and non-metallic film measurement. Here are some selection points and precautions:
Select point
1. Measurement range: When choosing a dual-purpose Film Thickness Gauge, the measurement range of the instrument should be selected according to actual needs. Generally, the measurement range of the instrument should be able to meet the application needs, and at the same time, do not over-purchase the measurement range higher than the demand to avoid unnecessary cost waste.
2. Measurement accuracy: Accuracy is an important indicator to measure the performance of dual-purpose Film Thickness Gauges. When choosing a dual-purpose Film Thickness Gauge, an instrument with sufficient high precision should be selected to ensure the reliability and accuracy of the measurement results.
3. Measurement principle: The measurement principle of dual-purpose film thickness meter usually includes magnetic induction, eddy current, X-ray fluorescence, etc. When choosing an instrument, the appropriate measurement principle should be selected according to the application requirements.
4. Measurement object: Different measurement objects have different requirements for the selection and operation of dual-purpose Film Thickness Gauges. For example, dual-purpose Film Thickness Gauges for measuring metal film layers and dual-purpose Film Thickness Gauges for measuring non-metallic film layers have different options and operation points.
5. Use environment: Dual-purpose Film Thickness Gauges are usually used in different environments, such as in laboratories, workshops, outdoors or outdoors. Therefore, when choosing a dual-purpose Film Thickness Gauge, the use environment should be considered to choose a suitable model.
Precautions
1. When using a dual-purpose Film Thickness Gauge, follow the instruction manual and perform calibration and maintenance as required.
2. Before measurement, the measurement surface should be cleaned to ensure measurement accuracy.
3. The use environment of the dual-purpose Film Thickness Gauge should be dry, dust-free, oil-free, non-corrosive gas, etc.
4. When using dual-purpose Film Thickness Gauges in different environments, pay attention to the influence of temperature and humidity on the measurement and make corrections.
5. Pay attention to factors such as the working temperature, power supply life and storage conditions of the instrument to ensure the long-term stable operation of the dual-purpose Film Thickness Gauge.
