Coal and rock analysis of coal quality instruments 17,000 ≠ 24,000, do you really understand?

This is a very simple reason. The use value of the equipment is reflected in its external price, the same equipment - micro-machine ash melting point tester: you bought it with 17,000 yuan, others used 24,000 yuan to buy. Such a situation where the price difference is so huge, is it just that you are stupid or the manufacturer is stupid? Will the manufacturer be stupid? As the saying goes, it will be better to buy it, and the manufacturer will not do the business of losing money. Since 17,000 yuan he sold to your computer automatic ash melting point measuring instrument, indicating that this equipment is not worth 24,000 yuan, it is really worth 24,000. Why? The main reason is that you do not understand the performance principle of the micro-machine automatic ash melting point tester. For example, some microcomputer ash melting point measuring instruments have the function of fully automatic photo saving, and some do not have this function; some have the function of comparing photos with standard pictures, and some do not. You said that the performance difference is so big, will its price be the same? This means that you can't compare his price when you buy a device. If the gap is large, you need to consider its use. Therefore, you must understand the equipment you buy, otherwise it is possible to buy "fake" equipment.
