These operations are required for every single measurement cycle. This centralized panel can therefore reduce the workload of A jog shuttle covering a wide range of speed is a standard feature.The drive unit can be moved easily to the measurement position by usingthe jog shuttle.Easy operation with X-axis jog shuttleCentralized front control panelKey operation buttons are now mounted onto the X-axis drive unit to reduce set-up time and improve high-volume repetitive measurement processess.Inside: Fine feedOutside: Coarse feedSpeed range: 0.02 - 20mm/sThe newly designed stand allows operators to quickly and easily move the drive unit to and from the measurement height without having to push or pull.Moreover, this stand is equipped with a reference stop for quick repositioning to the measurement height, which ensures an easy and highly efficient measurement flow.By enabling faster X-axis movement and enhancing the stylus up/down functions, the drive unit can return to the measurement start position after auto-displacement of the stylus. This is especiallyuseful when high volume repetitive measurements are being executed by a part program.A quick-vertical-motion stand with remarkable operabilityHighly efficient measurementHandleFine-feed knobUpside Bottom"Pursuing high accuracy is our mission"Introducing a new highly accurate digital scaleEasy setup for highly accurate and efficient measurementThe detector unit (Z1 axis) is equipped with a highly accurate arc scale. This scale directly tracks the arc trajectory of the stylus tip so that the most accurate compensation can be applied to the scale output, which leads to higher accuracy and resolution.The highly accurate digital arc scale not only improves measurement accuracy, but can also be set up easily.Measurement range of detector: 50mmAccuracy: ±(2.5+|0.1H |) μm, where H is displacementfrom mid-range position (mm)Resolution: 0.1μm (over entire measurement range)Light emitter receiverThe Circular ScaleDigital-scale detectorConstant ResolutionOperators are free from bothersome operations such as measurementmagnification switching and calibrating each magnification as required for analog instruments.The combination of high accuracy and excellent operability allows for increased support of a wide range of measurement needs.X-axis inclination handle is a standard featureA range of options available according to the applicationThe CV-2100 series * is equipped with a drive unit inclination mechanism that enables inclined-plane measurement without changing settings.Inclination angle (MAX): ±45°(For CV-2100M4)CV-2100N4Manual column stand for CV-2100N4*2CV-2100M4Desktop PC*1: If the CV-2100N4 is operated without the dedicated manual stand, the measuring range of the Z axis might be reduced, depending on the installation conditions. If you are considering using the CV-2100N4 without the stand, contact your local Mitutoyo sales office for advice.*2: Optional accessory (refer to page 13).*1* For CV-2100N4, a manual column stand No.218-042 (refer to P13) is required (optional accessory.)Contour Analysis Software: FORMTRACEPAKFORMTRACEPAK functions offer total support for measurement system control, surface roughness analysis, contour analysis, contour tolerancing, and inspection report creation.To make only a single measurement, you can create a part program in the single mode. To measure multiple workpieces of an identical shape, you can use the teaching mode.Since you can embed the entire flow, from making measurement to printing a report, into a part program, you can efficiently make measurements, analyze data, and output a report. A function is also provided that enables you to insert comments accompanied with photographs at desired timings, enabling you to embed the roles described in a measurement procedure document that specifies important points such as work settings.To make immediate measurements, you can use the pull-down menu to easily select and call up the desired operating procedure.Online help that can be viewed any time is incorporated into the software. In addition to index and keyword searches, a status saving help button, which displays menus and Windows help with a click of the mouse, is provided.You can hide buttons that are not used frequently. For example,you can choose to display only those buttons that are usedfrequently and increase the size of the displayed graphics window,thereby customizing the window to suit your needs.You can switch the language* to be used in the measurement,analysis, and layout windows.After measurements have been made, you can switch to another language and create a report in that language. This function can be used worldwide.* Supported languages: Japanese, English, German, French, Italian, Spanish, Polish, Hungarian, Swedish, Czech, Simplified Chinese, Traditional Chinese, Korean, Turkish, Portuguese.* Online help function supports only Japanese and English.Measurement controlOnline help function *Multiple language support (15 languages)Button-editing functionCircle and line automatic determination function Using the circle/line auto-fitting command, you can automatically calculate all circles and lines contained in the data without having to click the command button each time.Removal of abnormal points functionIrregular defects in the data are filtered out from the calculation. This function can effective when specifying the calculation range for locations at which the boundary between circle and line is difficult to determine.Text output of the calculation result and graphics data You can output the calculation result as text (in csv or txt format), output graphics data obtained from measurements as point-string data to a text file or CAD file (in the DXF or IGES format), or copy the data to the clipboard. Combined with commercial document or statistical processing software, this feature can be used to share data with computers that do not have dedicated analysis softwareinstalled or execute CAD-based reverse engineering.Contour analysis functionA wide variety of commands, which form the basicelements for analysis, are provided, including those forpoints (10 kinds), lines (6 kinds), and circles (6 kinds).A rich set of commands that combine these elementsto calculate angles, pitches, and distances, a contourtolerancing function, and a design value generationfunction are also provided as standard features. Thesefunctions, combined with the function that allowsyou to customize the calculation command buttons byhiding less frequently used commands, let you tailorthe window according to the user environment.Simple pitch calculation functionYou can efficiently analyze the pitch between identical shapes,such as a screw pitch or the distance between circles (center-to-center pitch), bysimply specifying thedesired range usingmouse operations.Example of range specification for screw threadpitch with rectangular tool.Contour-tolerancing function as a standard featureThe best-fit processing function that moves the coordinate values of the design data and measurement data to the optimum positions is provided as a standard feature. Measurement results can be displayed as graphics that show deviations of the measured contour from nominal with the tolerance values expanded in each coordinate for easy comparison. Results can also be output as a text file, or utilized as feedback data for machining systems.Contour AnalysisExample of contour-tolerancing result in graphical form Example of contour-tolerancingresults output as numeric valuesContour Analysis Software: FORMTRACEPAKContour AnalysisDesign value generation functionYou can generate design data from CAD data (DXF or IGES file) or text data. Furthermore, since you can also convert measurement data into design data, you can save parts data prior to use (testing) as design data and effectively utilize it for checking the wear following use (testing).Data combination functionYou can combine partial data collected separately from a work-piece (made necessary due to shape characteristics) into a single graphic for convenient analysis.Calculation command repetition settingWhen identical shapes have the same pitch, you can analyze all of the shapes in a batch by specifying a single analysis location and the pitch.Best-fit processing function for measurement point stringsThis function tries to fit the measurement points to the stored reference data on the same coordinate system. It can eliminate the effects of a shift that may occur when setting the workpiece during automatic analysis.Data superimposition commandYou can superimpose two sets of data by detecting their charac-teristic points. Use the mouse to drag and move the measurement point strings to the desired positions to be superimposed.Integrated layoutYou can use simple operations to lay out graphics obtained from measurements as well as measure-ment results for surface roughness, contour, and roundness on a single page.Furthermore, since the program now allows you to specify a saved file and paste it, you can easily paste results from multiple files.Note: the optional ROUNDPAK roundness/cylindricity analysis program is required. (Ver. 7 or higher)Element information barThis bar displays the attribute values of the pasted items, allowing you to easily check the contents of the pasted measurement data files.System layout printingBy simply selecting the items to be output, you can automatically lay out the page to be printed.Use this feature when you wish to simplify the printing task.Using the mouse to drag and drop the analysis content displayed in the element insertion bar, you can paste it into the layout. From the contour analysis result, you can also select the analysis result for a circle or line alone and paste it in position.Saving the result as a web pageSince you can save the result in html or mhtml format, which can be displayed using Internet Explorer or Microsoft Word, you can check the result even on a PC on which no layout-editing program is installed.Report creation functionYou can freely assemble measurement results/conditions/graphics as well as comments/circles/lines/arrows, and print them out in a measurement result report. Furthermore, since you can paste bitmap files, you can also add a workpiece image or company logo to the layout.You can also save the created layout and use it again later for similar measurements.Optional Accessories3-axis Adjustment Table: 178-047Table and fixture systemsThis table helps make the adjustments required when measuring cylindrical surfaces. The corrections for the pitch angle and the swivel angle are determined from a preliminary measurement and the Digimatic micrometers are adjusted accordingly. A flat-surfaced workpiece can also be leveled with this table. By using Mitutoyo’s 3-axis adjustment table, the workpiece can be aligned and leveled easily, simply by following the FORMTRACEPAK guidance.

• 目前国际上,浊度单位用法依然很多,在浊度单位上 还未达到规范化。
• 目前有四种常用浊度单位:“FNU”、 “NTU” 、 “FTU” 、 “度”等。

浊度标准物质
• 传统硅藻土标准,因稳定性差、配制繁杂、在线性 不佳等问题,在我国《饮用水卫生标准检验方法》 中,该标准物已被取消。
• 在70年代出现了福尔马肼标准溶液。 福尔马肼,由硫酸肼与六次甲基四胺在室温条
件下聚合,生成的一种白色高分子聚合。 《我国饮用水卫生标准检验法》中,统一使用福
尔马肼作为浊度标准。

浊度测量原理
• 水的浊度越高,则散射光就越强,而透射光就越 弱;反之,水的浊度越低,则散射光就越弱,而 透射光就越强。
• 通过测定散射光与透射光强度之间的变化,便可 测出水的浊度。

样品颜色对浊度测量的影响及消除
• 有颜色的物质对入射光产生吸收,如果一部分 散射光被吸收,则检测器检测到的散射光将减 少,测量的浊度值偏低。
12
颜色对浊度测量的影响及消除(续)
• 采用比浊计加以修正; • 在检测系统中额外增加一个水平方向上的检测
器,用以检测透射光强度,从而对测量结果加 以校正。

浊度 ?
浊度定义
天然水和废水中有很多颗粒性物质,如泥沙、 粘土、藻类及其他微生物、不溶性无机物和有 机物,会产生混浊现象。水样的混浊程度可以 用浊度来表示。

散射光浊度仪测量原理(1)
• 散射光浊度仪是应用光线的散射原理制成。 • 根据丁道尔效应:
I=kI0nV2/λ4
式中:I-散射光强度,I0入射光强度,λ入射光波长,n指单 位体积内的悬浮颗粒数,V颗粒体积,k常数。
可见,散射光强度与悬浮颗粒物的总数成比例,即 与浊度成比例。因此可由散射浊度仪测定水样浊 度。

颗粒物浓度对浊度测量的影响
• 数量较少的大颗粒对光的散射能力与数量较多 的小颗粒颗粒相当。 – 因此NTU值与mg/L之间的可比性较差。
10 = = NT
U
14
颗粒物浓度的影响及消除(续)
• 当入射光强度相同时,颗粒物浓度越高,它所 引起的光散射与吸收将会成倍增加。
• 为消除颗粒物浓度较高对测量结果的影响,可 在浊度仪光路中增设前向或者后向散射光检测 器。

散射光浊度仪测量原理(2)
由下图可见,90度方向的散射光,不受颗粒尺寸的影响, 因此浊度仪测量时采用90度散射光检测。这样,即使水样中 有不同尺寸的颗粒物但仍可取得较高的准确度。
微小颗粒 (<0.1λ)
中度大小颗粒 (0.25λ)
大颗粒 (>0.25λ)

散射光浊度仪测量原理(3)
为保证测量结果的准确性,浊度仪的设 计可以最大限度的减少颗粒物尺寸、数量、 颜色对测量结果的干扰。
前最常用的方法是仪器分析法,即光电浊度仪分 析法。
6
光电浊度仪的两种测量方法
光电浊度仪测量基本分为透射法和散射法两种。 国际标准化组织在其推荐的ISO7027中,也将散
射法和透射法定为浊度仪的两种标准测量方法。 透射法:用一束光通过一定厚度的待测水样并测
量待测水样中的悬浮颗粒对入射光的吸收和散射 所引起的透射光强度的衰减量来测定待测水样浊 度,该方法又可称为比浊法。 散射法:利用测量穿过待测水样的入射光束被待 测水样中的悬浮颗粒色散所产生的散射光强度来 实现,该方法又可称为散射浊度法。

浊度,即水体中有悬浮颗粒物时,会阻碍光线 透过水层(即通过水体的部分光线会被吸收或 散射,而非直接透射)。由悬浮性颗粒物对光 线引起的阻碍程度,可用浊度表示。
浊度是一种光学效应,它表现出光线透过 水层时受到阻碍的程度。

浊度单位的多种表示方法
• 国际标准化组织于1984年颁布的“ISO7027水质浊度 测量标准”,规定了浊度标准溶液(福尔马肼)的配 制方法以及浊度单位(FNU)。
