When we buy instruments, we also compare the same kind of goods and choose the best price-performance ratio. The price-performance ratio is the ratio between the performance and price of a product. However, what is the real cost-effectiveness of the instrument? How to determine the performance of the instrument? Many buyers will think it is the function of the instrument. Is this understanding correct? China Chemical Instrument Network Xiaobian and your instrument to unveil the cost-effectiveness of the instrument products.

In the instrumentation industry, many people still take it for granted that the ratio of product to function to price is the ratio of performance to price. At first glance, this is true, but it is not true in depth. The quality of the instrument is closely related to each other, so the accuracy of the instrument and the stability of the test results are the most important manifestations of the performance of the instrument.

Many people will say that the detection accuracy of the products on the market is almost the same, so their cost-effectiveness is relatively similar. This statement is true for most of the products on the market, but it seems inappropriate for analytical instruments. Most products in the use of excessive wear and tear. I'm afraid the most common problem is that the test data are inaccurate. For most tests, inaccuracy is not just a matter of error, it makes the test and the experiment meaningless. That is to say, if the test data of an instrument are worn out and aged, what kind of problems will happen? Inaccuracy and repetition do not mean that this instrument has lost its meaning.

Therefore, the price-performance ratio is not only the ratio of product function to price, but also the effective service life of the product. Instead of just looking at the product and price, we should consider the stability and accuracy of the test results after the product has been used for a certain period of time. The true embodiment.

The milligram instrument brand plug-and-pull force tester and the key switch load-displacement curve tester are the most cost-effective products with a high market share.
