How to choose test equipment and suppliers

With the development of science and technology, people's detection methods for products are increasing. The production and suppliers of experimental instruments have also sprung up. How to choose the right experimental equipment and excellent suppliers is the primary concern of the majority of users. Beijing Hongda Tianmao Testing Equipment Co., Ltd. based on more than ten years of production and sales experience for everyone to do some analysis.
1. Determine what standard test is used for the object to be inspected. China's current testing standards (national standard GB, Ministry standard JB, line standard HB), and international standard ISO or American standard ASMI.
2. Determine what method is used to detect a) lossy (detection method of taking part or deforming the object to be inspected, high detection accuracy; slow detection speed): chemical analysis, physical test.
b) Non-destructive (detection method without damage to the tested object, detection accuracy is relatively low; detection speed is fast): ray, sound wave, electromagnetic, infiltration, mirror phase.
3. Sensor selection sensor: Converts the quantity to be detected into a part that we can display, calculate or can input to other machines. The detection accuracy depends mainly on it.
4. The detection accuracy and the applicable range are determined by the small detection amount of zui big and zui of the detected article, combined with 1, 2, and 3. Select the sensor accuracy and range value close to zui, this value is higher than the general price.
5. The performance price of the test product is more new than the product function, and the price is high. (Performance/price) The results obtained are judged and the value is high. The electronic product update cycle is short, and it is not advisable to purchase a very new soft technology (soft technology: operation interface, good senses, and constant accuracy).
6. National standardization of testing products, the measuring instruments used in the test must pass the standard measurement identification (yearbook).
7. Testing product after-sales service For testing equipment and instruments with longevity, pay great attention to the promise of maintenance and renewal.
8. Detecting the service life of the product, supplying the ray generating device of the wearing parts, electronic vacuum device, mechanical wear parts, mirror natural corrosion
9. Detecting the user base of the product The user is relatively stable with the product and the spare parts are easy to repair.
10. Technical Training Product distributors must have higher technical strength and be able to provide more technical training to improve our use of purchased instruments and proper maintenance methods.

Summary Hemp Seeds are rich in healthy fats and essential fatty acids. They are also a great protein source and contain high amounts of vitamin E, phosphorus, potassium, sodium, magnesium, sulfur, calcium, iron and zinc.
Hulled Hemp Seed, which is the whole seed with the crunchy outer shell removed, comes by quite a few names like Hemp Hearts, shelled Hemp Seed and hemp nut. Since the hulls of the hemp seed are quite crunchy and contain a lot of fibre, we as a society are not used to eating this kind of item.
