Product Description

The use of the toroidal method to evaluate the adhesion of coatings and substrates is the most traditional method. This method uses a specially designed instrument to draw many circles of the same diameter on the measured coating in succession, with the circles overlapping at a certain distance, and then divided into seven parts according to the size of the parts where the circles intersect. When evaluating the integrity of the paint film, the corresponding grade should be evaluated in an area above 70% of the coating.

Product Features

1. Full alumina body, high-grade, beautiful and lightweight

2. The special indicator light automatically determines whether the pin can be broken into the bottom material, which has the characteristics of accurate and convenient operation

3. The test results are highly reproducible and comparable

4. The sliding platform makes it easy to perform multiple tests on the same test board

5. The rotating working arm design is very convenient for changing needles and changing test plates

6. The double nut is used to adjust the screw gap, the platform runs more smoothly, reduces the error caused by the thread gap, and the data is more accurate

7. The working platform adopts a two-way limit, which is more stable than a single rail.

8. Once the test is complete, the key can be returned to the starting point

9. It is more convenient and faster to use special tools to pull out the needle

10. Precision machining threads control the round diameter, and the test results are more accurate

11. The platform begins and ends with precise positioning, ensuring that each test meets a standard timeline

12. Multi-level weight combination to get the most appropriate weight.

13. The independent rotation design of the weight plate reduces the effect of inertia on the test load.
