Today, We and you discuss the evolution of the industry testing instrument. I don’t know how many years ago the user came to the Defelsko machine (at least 15 years, because the small line contact Defelsko is already figure 2), the former Defelsko coating thickness gauge frankly this design is very common today. But it was amazing to have such an accurate instrument a decade or two ago! It’s an exaggeration that this customer is still using…

Here’s the PosiTector 200 series, which measures the thickness of coatings on wood, polyester and concrete. This was a really great product when people were still using mechanical magnifying glasses to see at a glance and calculate one by one. But there are also some customers feel expensive (than the magnetic induction and eddy current coating thickness gauge is much higher), so many times in some large enterprises (not bad money) used more.

The following is the matching probe. The main thing is that the matching probe is different for different substrates. You can learn more about this with us. But it must be said that if a coating thickness gauge can be used for 10 years, the accuracy has not been discounted, its quality can be imagined.

Vaguely remember that Defelsko’s outer packaging was a white ordinary to ordinary box, at that time I often joked about, a little bit of a flower inserted in the cow dung feeling. But then I changed it, and it was a good change. In addition, the appearance of the new machine has also changed, more and more with the beauty of industrial design.

During the training, the instructor threw the machine (more than 1 meter high) directly on the platform to prove its durability. Anyway, later the north and South tide bought their own money to buy the machine is not dare to fall, although I know that it is not bad. It’s like swimming with your cell phone now. You know you can, but you don’t dare.

A lot of verbose, or back to the topic, for this kind of detection instrument, we can also talk about so many years from the appearance, parameters, function and even the evolution of durability, science and technology in progress, process in progress, aesthetic progress, on the contrary, the price is reduced. Although these testing instruments are not available to the general public, for testing and scientific researchers, they truly enjoy the benefits brought by science and technology. This is probably the meaning of scientific and technological progress! What do you think?
