How to identify the true and false plastic metal separator?

In recent years, as more and more attention is paid to the detection of metal pollutants in products, the market for the principle of plastic metal separators has become more and more prosperous. Therefore, there are also many illegal metal separator manufacturers in order to make money. , which has greatly disrupted the healthy development of the plastic metal separator industry. In order to enable consumers to buy high-quality plastic metal separators, I will share with you the identification method of true and false plastic metal separators: 1. Because the fake metal separators are made of permanent magnet steel, which is the shape of the machine and equipment Similar to its principle and technology, it cannot be changed. After purchasing the machine, the customer can use the simplest adjustable wrench to place it on the inner side of the detection probe, which is what we call the effective detection area. If the probe has an adsorption adjustable wrench, it can be basically concluded that what you have purchased is a stainless steel machine, that is, a fake metal separator, because the inside of the real metal separator probe is composed of coils and filling fillers. When there is no current passing through and no signal is sent, the product will not be magnetically adsorbed. The stainless steel needle detector is different. The stainless steel needle detector uses a magnet in the probe, which has a natural magnetic adsorption phenomenon. 2. Tear off a small piece of tin foil lined with the cigarette box for testing. The principle of the fake plastic metal separator is that this piece of tin foil cannot be detected. It is true that even a small piece of tin foil from the new brand metal separator will not be detected. Alarms can be detected to determine the 'true and false' of these metal separators. 3. The second thing is to look at the price. Although the prices of metal separators in the market are different, the main price range is not very different. If the product quotation you receive is lower than 30% of this price range, then you need to Be careful, after all, you get what you pay for.
