The choose and buy instrument which problems should be paid attention to

Instrument which problems should be paid attention to the choose and buy one, based on the need of company products, the choose and buy spectrograph's goal is to guarantee the company a quantity to reach a stem of their products, because this should pay attention to spectrograph to the company's products fit, like a furnace before test time as possible, incoming inspection experience need to be able to print the test report, while product inspection experience thinking problem to the authority of spectrograph. Second, the demand for spectrograph based on company size is usually divided into three categories large, medium and small. Large companies usually decorate can be equipped with high frequency infrared carbon sulfur analysis instrument, two spectrograph, direct reading spectrometer laboratory cost can stem in 1 million yuan. Three condition, is simple, economic, not solid companies can consider problems with layout of water carbon sulphur analyzing instrument, model 721 spectrophotometer, 328 ab analysis to set up laboratory scale, planning to build a 15 square laboratory valued at $ten thousand. Like so far most domestic companies in our country, as well as content quality stem needs, and to do the test early and accurate, and can be equipped with decorate a half a high degree of automation of gas volume carbon sulfur high-speed analysis instrument and running a logo elements analysis instrument, whole lab cost in 1. 50000 yuan to 1. 80000 yuan between legal tender in our country. The four, led products such as steel, steel wire rope production units for professional requirements of the spectrograph can be appropriate to reduce, and like the casting of copper alloy, aluminum alloy, stainless steel and other companies should be surprisingly attaches great importance to the spectrograph professionalism, normally specialized spectrograph test is very accurate and convenient. Five, in quality, price and service aspects of the spectrograph is mainly ponder question spectrograph supplier service experience, product spectrograph so far as quality is better than large direct reading spectrometry overseas for domestic products, the price is not comparable, the file spectrograph is in product quantity, performance more than god like shaw, slightly different functions. Six, non-ferrous metal manufacturer if without calibration carbon sulfur content, as long as the choose and buy a logo multielement analysis instrument and the sample balance, plus all chemical container glass and complete sets of chemical reagent, the total price is in ten thousand yuan. www。 wuxiyibiao。 com
