Appearance evolution of Defelsko coating Thickness Gauge to see the progress of industrial testing instruments

Today, NBCHAO will discuss the evolution of industry testing instruments with you. It just so happens that where did the user come from? I don't know how many years ago the Defelsko machine (at least 15 years, because the Defelsko that I came into contact with is already in Figure 2), and the previous Defelsko coating Thickness Gauge. Honestly, this design is very common today. But it was also very NB to have such an accurate instrument ten or twenty years ago! It's an exaggeration that this customer is still using...

The following is the PosiTector 200 series, which mainly measures the thickness of coatings on wood, polyester plastics, and concrete. This was a really great product when everyone was still using mechanical magnifying glass to look at it at a glance and calculate one by one. But there are also some customers who think it is expensive (much higher than the coating Thickness Gauge of magnetic induction and eddy current), so it is often used more in some large enterprises (not bad money).

The following is a matching probe. The main thing is that the probes matched with different substrates are different. This can be explained to us for details. But it must be said that if a coating Thickness Gauge can be used for 10 years without discount, its quality can be imagined.

I vaguely remember that the outer packaging of Defelsko was a white and ordinary box. At that time, I often complained that it felt like a flower was inserted into cow dung. But it was changed later, and it was not bad. In addition, the appearance of the new machine has also been changed, and it has more and more the beauty of industrial design.

During the training, the instructor threw the machine (more than 1 meter high) directly on the podium to prove its durability. Anyway, the machine that NBCHAO bought at his own expense did not dare to fall, even though he knew it would not break. This is the same as swimming with a mobile phone now, you know you can, but you dare not.

For this type of testing instrument, we can also talk about the evolution of appearance, parameters, functions and even durability over the years. Technology is improving, craftsmanship is improving, and aesthetics are improving. On the contrary, the price is decreasing. Although these testing instruments are not used by the general public, for testing and scientific researchers, they really enjoy the benefits brought by technology. This is probably the meaning of scientific and technological progress! What do you think?
