How can one prevent buying fake instruments? Give some advice! Thank you all!

Purchase from reputable manufacturers, sign long-term supply contracts with quality guarantees; in short, don’t prioritize low prices.

Damn. . . Your leadership is really amazing. . . . How to avoid buying fake products? ? ? Can it be done with just one system? ? ? ? ? So are there any other counterfeit and substandard products in China? Melamine – not because of any deaths – is still likely to be widely used today. . . Milk mixed with cow urine. Fruits are filled with water. Swelling agent. . Ractopamine. . Preserved and refurbished meat. . . There are also various counterfeit currencies. . Enrich the Chinese people by printing RMB excessively. . . . . All of them are fake and of poor quality

First of all, it is necessary to choose a manufacturer with compliant manufacturing qualifications; a TS certificate is a basic requirement, and the registered capital should not be too low – at least 50 million or more. Examine the manufacturer’s production scale and equipment technology, and inquire about their reputation and performance.

The poster is probably in charge of procurement; it’s really not easy to formulate such a system. It would be better if it were written as a set of management guidelines, or perhaps as evaluation criteria. Detailed specifications are needed, both from a business perspective and from a technical standpoint

I guess you’re not looking for large state-owned enterprises, as fake products are unlikely to be found there; at most, small factories may have poor quality products. For large companies, it’s sufficient to find them directly; there’s no need to seek agents or conduct on-site inspections.

It’s hard to explain in just a few words; why don’t you add me on QQ at 534303628 so we can discuss it together? I have been working in instrumentation for almost 20 years

I’ll purchase a dog and have it answer once. Buying fake products means acquiring substandard items. Fakes are not necessarily substandard, but anything that is substandard must be a fake. Purchasers must always keep in mind one thing: you get what you pay for. If you pay three times as much, you should get twice as good a product; if you pay ten times as much, you should get three times as good a product. If a manager gives you a price that is only enough to buy a low-quality imitation and expects you to purchase the genuine version, then confront him immediately! Hehe, to get back to the point: controlling the quality of products actually means controlling the supply channels. 1. If your company allows payment on credit terms, then the suppliers are usually fixed traders or large cooperating enterprises; these suppliers are evaluated periodically, and those whose products frequently have problems are removed from the list of approved suppliers and will never be used again. 2. If it was purchased with cash in the market or through a bank transfer without any down payment, then call the brand’s factory directly; they usually have a 400-number for customer service. If the amount is small, ask who the local authorized dealer is and purchase from them. 3. For newly purchased products or new brands, please visit the website “Tianyancha” to check the company’s registered capital, risk levels, patents, and other information, in order to verify the company’s details. Do not purchase from companies that cannot be found. 4. If you’re really unsure, post it on Haichuan Forum – everyone there is an experienced user who will resolve it for you in no time.

There are still higher-ups above those in charge, and he too is forced into this situation; I understand him very well. Moreover, what you mentioned is indeed a serious issue, and such matters need to be resolved through legal channels and oversight mechanisms
