Coating thickness gauge selection skills
(1) Detailed Rules for Type Selection Notes
1. Why choose the ring test coating thickness gauge, what are the advantages of the ring test product?
Answer: First of all, the ring test products have very high quality assurance, have the largest and most advanced production line in China, and have a production history of nearly 20 years. The current domestic share is more than 70%. In terms of service, the ring test company has many domestic branches. , hundreds of agencies, to maximize the realization of local purchases and repairs nearby. As a high-paying technology company listed on the Shenzhen Stock Exchange with testing instruments as its main business, the company has very strong strength in production, development and sales.
2. What kind of coating material is mainly measured by the ring measurement coating thickness gauge?
Answer: The ring coating thickness gauge can measure the thickness of the non-magnetic coating on the magnetic metal substrate and the thickness of the non-conductive layer on the non-magnetic metal substrate.
3. Can the ring coating thickness gauge measure the coating on non-metallic materials?
Answer: At present, the coating thickness gauge produced by the ring test is not able to measure the coating thickness on non-metallic materials. It can only measure the coating of non-magnetic materials on iron bases and the thickness of insulating layers on non-ferrous base metal materials.
Another: For the coating measurement of non-metallic substrate materials, electrolysis, X-ray, ultrasonic coating and other instruments can be selected at present, but all methods have advantages and disadvantages. Electrolysis will destroy the material, and X-ray thickness gauges are relatively expensive. The accuracy and stability of the coating thickness gauge is not very good. At present, many users use the era thickness gauge to measure through indirect methods, for example: spraying metal materials and non-metallic materials at the same time during the spraying process, and then measuring The thickness of the metal coating indirectly obtains the thickness of the spraying of non-metallic materials.
4. Can the ring coating thickness gauge measure the coating of high temperature materials?
Answer: The ring thickness gauge cannot measure high-temperature materials. In principle, it can only measure materials below 60 degrees.
5. Can the ring coating thickness gauge measure the thickness of the nickel coating?
Answer: No! Because nickel is both magnetic and conductive, the thickness of the nickel coating cannot be measured.
6. The coating of our factory is a fireproof material with a thickness of 5-8 millimeters. Can you use your factory's products for measurement.
Answer: Optional TT260 with F10 probe can measure the coating thickness of 0-10mm.
7. The inner and outer walls of the steel pipe are coated, can it be measured?
Answer: There is a special F1/90 probe for the electroplating layer on the inner wall of the pipe that meets the requirements of the measurement material, and the minimum radius requirement: R>7mm is enough.
8. Can the coating be measured at about 5 microns? Which instrument is more suitable?
Answer: The optional ring test F400 probe can stably measure the thickness of 5um
9. Can chrome plating on copper be tested?
Answer: The ring test eddy current thickness gauge can measure chrome-plated workpieces on copper, but the chromium layer must be less than 40um.
10. Can it measure the thickness of film and paper?
Answer: The thickness of films and papers that meet the thickness requirements can be measured by lining the bottom with a metal substrate. Currently, there are many customers for this application.
11. Can the ring thickness gauge measure the thickness of the thread coating on the screw?
Answer: The thickness of the thread coating on the screw with a relatively small diameter cannot be measured by instruments in the current era.
12. Under what circumstances should the communication software be selected, and what functions does the ring test communication software have?
Answer: At present, the TT260 of the ring measurement coating thickness gauge can be equipped with communication software. The new version of the software has been upgraded on the basis of the original software. It has powerful functions and strong practicability, including online download, data storage, measurement analysis, technical support, etc., and output methods There are WORD documents, EXCEL tables, TXT texts, and HTML web pages, which can realize real-time transmission and real-time printing with computers. When the user needs to systematically analyze the measurement data and establish a database, it is recommended to use the Times TT260 communication software.
13. What material is the CN02 probe used to measure?
Answer: The CN02 probe is specially used to measure the thickness of copper foil on the circuit board, and the range is 0-200um
