When it comes to the pencil Hardness Tester, the national standard GB/T 6379-1996 has made clear regulations, and its load weight is 1000±5g, but when it comes to GB/T 6379-2006, it is changed to 750±10g. In fact, before this, there have been three specifications of pencil Hardness Testers, namely 500g, 750g and 1000g. One point of view is that if the substrate is relatively soft, choose 500g, otherwise, choose 1000g, and if it is in between, choose 750g. Judging from the user's choice tendency after the release of the new standard, most of them choose the middle 750g. In this issue, we got the Dutch TQC VF2378 pencil Hardness Tester for evaluation, which is also a 750g pencil Hardness Tester.
<1>VF2378 Pencil Hardness Tester is equipped with 1 pencil Hardness Tester and 20 original pencils with hardness ranging from 8B to 10H, and a pencil sharpener for sharpening pencils. In terms of configuration, it is quite satisfactory, and it is not good or bad.
<2> From the appearance point of view, VF2378 is undoubtedly a very design-intensive Hardness Tester. Whether it is in terms of color matching or load weight placement, at least from the mainstream products in the market, VF2378 is a very NB product. .
<3> From the perspective of craftsmanship, the workmanship of VF2378 is almost impeccable, whether it is the selection of materials, the treatment of external panels, or even the treatment of details. Don't underestimate this point. We know that the instruments used to measure paint are often stained by wet paint. After the experiment is finished, the stained place will have dried and solidified. It will be very troublesome to clean at this time. In addition, if the panel design is too smooth, the experimenter holds a pencil Hardness Tester with a weight of about 750g, and the result can be imagined. VF2378 is not so smooth, nor is it very rough. This shows that TQC, a European manufacturer, has put great effort into product design and workmanship.
<4> From the actual measurement, the TQC VF2378 pencil Hardness Tester slides on the painted aluminum plate, and the whole process is very smooth. The author once played with the pencil Hardness Tester, which is said to be very cheap. Let’s not talk about it, but the entire wheel is made of plastic, and the horizontal axis supporting the wheel in the middle is actually leaking when it passes through the body of the pencil Hardness Tester. The pencil draws the correct scratches evenly in the hand. The wheels of the VF2378 are made of stainless steel and rubber tires, which make the service life longer while absorbing shock.

<5> From the point of view of quality, TQC's product R & D personnel specially equipped the standard factory certification certificate for this mainstream 750g pencil Hardness Tester. As far as we know, it is the standard certificate for one of its three different models. product. Moreover, its pencils are not like the domestic ones that just take a bundle of rubber bands and finish the job, but considering that its products are exported to the world, and the damage to the pencils may be caused during the intermediate transportation, an iron specially used to protect the pencils is adopted. box. Also for everyone to appreciate.
