When do RoHS testing most appropriate? A: RoHS Directive mandatory implementation time from ending today until July of next year, leaving only a little more than half a year's time, therefore, it should be said that the sooner the better, the sooner the more active, ROHS detector origin, later the more passive, in fact a lot of the high sensitivity of large enterprises, already started this work, and one clearly defined procurement of parts and raw materials must be passed RoHS testing products, the second is to own the whole product RoHS testing, while the majority of domestic and foreign buyers also put forward specific demands manufacturers, who did not pass the test of RoHS products will not sign a single. So, if your product does not do the test as soon as possible, the market will be lost, ROHS, vain regrets. Where, ROHS detector brand, λ is the wavelength spectrum analysis; d is the crystal lattice spacing; θ is the diffraction angle; n is the diffraction order. Use goniometer can measure the diffraction angle spectrum analysis, the use of the formula to calculate the corresponding wavelength element being analyzed, ROHS detector edx1800, to obtain characteristic information measured elements. Energy dispersive ray fluorescence spectrometer is used energy detector, by measuring the amount of charge collected by the detector, direct access to feature-ray energy emitted measured elements: Q = kE where, K is the photon energy of the incident radiation; Q is detected k for different types of energy response of the detector parameters; the corresponding amount of charge generated. The amount of charge proportional to the energy of the incident radiation, so by measuring the amount of charge available analyte feature information. ROHS detector edx18008, Sheng Ding equipment (certified), ROHS provided by the Dongguan City Ding Sheng Precision Instrument Company. Dongguan Sheng Ding Precision Instrument Co., Ltd. (www.dgshengding.com) (www.dgshengding.com) Dongguan, Guangdong, dedicated instrumentation leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. Sheng Ding instrument in leadership with the staff warmly welcome all inquiries negotiations to create Shengding instrument better future.
