　　三、測(cè)試原理：

　　利用物質(zhì)對(duì)不同波長的光呈現(xiàn)選擇性吸收現(xiàn)象來進(jìn)行物質(zhì)的定性和定量分析。如果被測(cè)溶液是透明的，當(dāng)一束定向入射光I經(jīng)過溶液時(shí)，能檢測(cè)到定向透射光IC的光強(qiáng)度；若溶液存在不同程度的渾濁，當(dāng)定向入射光I經(jīng)過溶液時(shí)，必定會(huì)產(chǎn)生光的擴(kuò)散，從而定向透射光IC的光強(qiáng)減小，因此只要準(zhǔn)確測(cè)量出定向透射光IC的光強(qiáng)大小，**能定量反映出溶液的透明度。

　　Third,the test principle:

　　The qualitative and quantitative analysis of substances is performed by the selective absorption of substances with different wavelengths of light.If the measured solution is completely transparent,when a beam of directional incident light I passes through the solution,the light intensity of the directional transmitted light IC can be detected;if the solution is turbid to varying degrees,when the directional incident light I passes through the solution,it must be Due to the diffusion of light,the light intensity of the directional transmitted light IC decreases.Therefore,as long as the light intensity of the directional transmitted light IC is accurately measured,the transparency of the solution can be quantitatively reflected.

　　Eight,instrument daily maintenance:

　　This instrument is a precision optical instrument that has been carefully assembled and debugged before leaving the factory.If the instrument can be properly maintained and maintained,it will not only ensure the reliability and stability of the instrument,but also extend the service life of the instrument.

　　1 Provide a good working environment for the instrument according to 4.1.

　　2 During the test,care should be taken to prevent the solution from splashing into the sample rack and sample chamber.The cuvette containing the test solution should not be left in the sample chamber for a long time.

　　3 Pay attention to protect the optical window(light-transmitting surface)of the cuvette.In addition to not scratching,the main reason is to prevent the optical window from being contaminated.Wash it promptly after use,ａnd do not attach residual samples or washing liquid to the optical window to maintain its good matching.

　　4 After each use,check whether there is any overflow solution in the sample chamber.Wipe the sample chamber frequently to prevent the liquid from corroding parts or optical components.

　　5 After the instrument is used,a dust cover should be installed.A desiccant bag can be placed in the sample room to prevent moisture,but it must be removed when the device is turned on.

　　6 The daily use and storage of the instrument's LCD display and keyboard should be protected from scratches,water,dust and corrosion.

　　7 Perform regular performance index inspections and contact your local product distributor or company sales department if problems are found.Professional maintenance personnel should not open the case for repair without authorization.

　　8 When the instrument is not used for a long time,pay special attention to the environmental degree and humidity.A is better to place a desiccant bag in the sample room and replace it regularly.
