Today, the Shandong Puchuang editor will provide you with a detailed analysis of the advantages and disadvantages 

of different types of thin film thickness gauges, and recommend a high-performance thin film thickness detection 

device to meet your measurement needs.   

1、 Classification and advantages and disadvantages of thin film thickness tester

1）. Mechanical contact thickness gauge

Advantages: Simple structure, easy operation, relatively low price.

Disadvantages: Direct contact with the film is required during measurement, which may cause damage to the sample; 

The measurement accuracy is affected by probe wear and sample surface flatness.

2）. Laser thickness gauge

Advantages: Non contact measurement, suitable for high-precision and high-speed measurement; Wide measurement 

range, suitable for various materials.

Disadvantages: High equipment cost; There are certain requirements for the measurement environment, such as light 

and temperature.

3）. Ultrasonic thickness gauge

Advantages: Wide measurement range, suitable for various materials; Easy to operate and low maintenance cost.

Disadvantage: Accuracy may decrease when measuring extremely thin or uneven thin films.

4）. Electromagnetic induction thickness gauge

Advantages: Fast measurement speed, high accuracy, especially suitable for measuring metal thin films.

Disadvantage: Not suitable for measuring non-metallic materials.

2、 How to purchase the most suitable thin film thickness tester?

When purchasing a thin film thickness gauge, the following key factors should be considered:

1）. Measurement accuracy: Determine the required measurement accuracy based on application requirements;

2）. Measurement range: Ensure that the selected instrument can cover your measurement needs range;

3）. Material type: Different thickness gauges are suitable for different types of materials, and the characteristics of the 

tested material should be considered when selecting;

4）. Convenience of operation: Consider the usability of the instrument, maintenance costs, and whether professional 

training is required;

5）. Budget: Select the most cost-effective equipment based on the budget range;

6）. After sales service: After sales service is an important link in the process of purchasing equipment. High quality 

suppliers will provide technical support and training during equipment use to ensure that you can fully utilize the 

functionality of the instrument.

3、 Recommended film thickness tester:

The Shandong Puchuang Film Thickness Gauge PTT-03A is used for thickness measurement of various plastic films, 

sheets, diaphragms, etc. It has the following advantages:

1）. High precision measurement: suitable for thickness measurement of various hard and soft materials such as thin 

films, composite films, paper, metal foil, and hard sheets within a range of 2mm, with a resolution of up to 0.1 μ m;

2）. High definition color LCD screen: intuitively displays the analysis data results such as maximum value, minimum 

value, average value, and standard deviation of the test;

3）. Touch screen control: The host can operate independently without the need for a computer, store and query test 

results, and simplify the operation process;

4）. Micro printer: Quickly print measurement results to improve work efficiency;

5）. Automatic saving of test results: The instrument automatically saves the test results, which can be viewed and

 printed at any time;

The above is the method for selecting a thin film thickness gauge. If you are choosing a reasonably priced and high-

performance thin film thickness gauge, you may consider Shandong Puchuang. We believe it will bring great convenience

and benefits to your material testing and quality control work.
