Several problems that users should pay attention to when purchasing instruments

first, according to the needs of enterprise products, the purpose of purchasing instruments is to ensure that the quality of enterprises' own products is controlled, so we should pay attention to the adaptability of instruments to the operation method of wire rope tensile testing machine. For example, the test time before furnace should be as fast as possible, It is better to have the upper edge of the scale at the level for incoming material inspection. The full digital measurement and control system of Jinan new era assay instrument Co., Ltd. can realize the closed-loop control of force, displacement and deformation, print the test report, and the authority of the instrument should be considered for finished product inspection

the professional requirements of single products such as steel, steel wire rope and other production units for instruments can be appropriately reduced, while enterprises such as cast copper alloy, aluminum alloy, stainless steel and so on should pay special attention to the professionalism of instruments. Generally speaking, the testing of instruments with strong professionalism is more accurate and convenient

according to the scale of enterprises, the demand for instruments is generally divided into three categories: large, medium and small. Large enterprises can generally be equipped with high-frequency infrared carbon sulfur analyzers. The direct goal of direct reading spectrometer II is to develop instruments beyond the current development stage of liquid lithium batteries, and the laboratory cost can be controlled at about 1million yuan

enterprises with relatively poor conditions and poor economy for the time being can consider configuring non-aqueous carbon and sulfur analyzer, 721 spectrophotometer and 328ab analytical balance to prepare for the construction of a laboratory. The total price of preparing to build a 15 square meter laboratory is less than 10000. For example, at present, most domestic enterprises in China should not only meet the needs of quality control, but also achieve timely and accurate testing. They can configure a high-speed carbon sulfur analyzer by gas volumetric method and a microcomputer element analyzer with a high degree of automation. The cost of the whole laboratory is between 15000 yuan and 18000 yuan

if non-ferrous metal manufacturers do not need to measure the content of carbon and sulfur, they only need to choose a microcomputer multi-element analyzer and weighing balance, plus all chemical glassware and a full set of chemical reagents, and the total price is about 10000 yuan

in terms of quality, price and service of instruments, the service ability of instrument suppliers is mainly considered. At present, the quality of high-end products and instruments, such as large-scale direct reading spectrum, foreign famous products is better than domestic products, and the price is not comparable. The quality and performance of domestic medium-sized instruments are mostly the same, with slight differences in functions

generally speaking, the service quality of manufacturers is better than that of merchants, and the service at the point of sale is more timely, but it also depends on the public service of each manufacturer to the society. Commitment content, especially the maintenance outside the warranty period of the instrument and the supply of spare parts and consumables
