The production requirements of single products such as steel, steel wire rope and other production units can be appropriately reduced, and enterprises such as cast copper alloys, aluminum alloys, and stainless steels should pay special attention to the professionalism of instruments. Generally speaking, instrument testing with strong professionalism More accurate and convenient.
According to the scale of the enterprise, the demand for instruments is generally divided into three categories: large, medium and small. Large-scale enterprises can generally be equipped with high-frequency infrared carbon and sulfur analyzers, direct-reading spectrometers, and the cost of laboratories can be controlled at about 1 million yuan.
Enterprises with relatively poor conditions and temporarily affluent economy can consider configuring a non-aqueous carbon and sulfur analyzer, a 721 spectrophotometer, and a 328AB analytical balance to prepare a laboratory. The total price of a 15 square laboratory is less than 10,000 . Like most of the domestic enterprises in China, not only to meet the needs of quality control, but also to make timely and accurate tests, can be equipped with a high-volume gas volume method carbon and sulfur high-speed analyzer and a microcomputer element analyzer, The cost of the entire laboratory is between 15,000 and 18,000 yuan.
If the non-ferrous metal manufacturers do not need to determine the content of carbon and sulfur, as long as they purchase a microcomputer multi-element analyzer and weighing scale, plus all chemical glassware and a full set of chemical reagents, the total price is about 10,000 yuan.
In terms of the quality, price and service of the instrument, the service capabilities of the instrument supplier are mainly considered. At present, the quality of high-end products 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 are similar, but the functions are slightly different.
In terms of service, manufacturers generally have better service quality than merchants. The service provided by sales outlets is more timely, but it also depends on the public services of various manufacturers to the society. Commitment content, special consideration for maintenance beyond the warranty period of the instrument and supply of spare parts and consumables.
First of all, according to the needs of enterprise products, the purpose of purchasing instruments is to ensure that the quality of the enterprise's own products is controlled, so we must pay attention to the adaptability of the instruments to the enterprise's products. Like the pre-furnace test, the test time should be as fast as possible. Can print test reports, and the inspection of finished products should take into account the authority of the instrument.
