二、税收编码的定义与重要性税收编码是指为了便于税收征管,对各类商品和服务按照一定的分类标准进行编码。

税收编码是税收征管信息化的基础,能够提高税收征管的效率和准确性。

通过对商品和服务的税收编码,可以方便地实现税收的征收、管理和查询。

此外,税收编码还有助于防范税收风险,打击偷逃漏税行为,维护国家的财政利益。

三、体表参考电极税收编码的相关规定在我国,体表参考电极作为一种生物医学领域的产品,其税收编码具有一定的特殊性。

根据《商品和服务税收分类与编码》,体表参考电极归属于“06.15.99”这一税目,即“其他未列明的医疗、外科、牙科及兽医用品”。

这一税目的编码为“100000000”,表示体表参考电极在税收上的归属。

四、应用实例与注意事项体表参考电极广泛应用于生物医学领域的研究和临床实践,如心电图检测、脑电图检测等。

在使用体表参考电极时,应注意以下几点:1.选择合适的体表参考电极。

根据测量对象和测量目的的不同,选择合适的电极材料和尺寸。

2.确保电极与生物组织良好接触。

良好的接触能够提高测量的准确性。

3.注意保护电极。

避免电极受到污染、损坏或失去导电性能。

4.遵守相关法律法规。

在购买和使用体表参考电极时,应遵守国家的税收法规,确保税收的合规性。

综上所述,体表参考电极作为一种重要的生物医学领域产品,其在税收上的归属为“100000000”。

注响应供应商须对采购项目内容中的技术要求逐条响应

注:响应供应商须对“采购项目内容”中的技术要求逐条响应。

如有缺漏,缺漏项视同没有实质性响应谈判文件要求,作无效响应处理。

一、供应商资格要求1、符合《政府采购法》第二十二条规定,具备独立法人资格;2、参加政府采购活动前三年内,在经营活动中没有重大违法记录;3、必须取得针对本项目采购人在用主要仪器设备的售后服务支持函,保证其供货能力;4、本项目不接受联合体参加谈判。

二、项目概况1、采购编号:\2、采购项目名称:2016年顺德区地表饮用水源在线监测仪器维修配件采购3、采购预算:人民币69.5万元4、项目报价要求:响应供应商应对所有招标内容进行响应,不允许只对其中部分内容进行响应。

本项目报价为全包价,包括本项目所有产品、配件、运输装卸、配套工程安装调试、培训、售后服务等伴随的服务及各种税费等完成本项目内容及合同实施过程中全部所需的一切费用。

以人民币为结算单位。

三、采购项目技术要求(一)项目基本内容和背景顺德区地表饮用水源水质在线监测系统由6个子站、1个咸潮预警监测站和1个中心监控系统服务器组成。

6个子站有18个水质参数(水温、pH、溶解氧、电导率、浊度、高锰酸盐指数、总磷、氨氮、硝酸盐氮、氟化物、氰化物、总酚、挥发酚、总砷、铜、镉、铅、硬度)的监测能力,咸潮预警监测站只监测氯离子1个参数。

水质自动监测站的仪器设备每年需要购买维修配件用以维修出现故障的设备,考虑到所购买的配件不是一次性更换或者使用,即有随机性,所以需要有熟知现场设备运转的技术人员的长期跟踪和配合。

其次,采购人在用的主要仪器设备均为进口设备,必须采购原装的与现有进口设备相匹配的维修配件,才能保证更换维修配件后的设备能够恢复正常运行,故本次维修配件采购采用单一来源方式申购。

具体水质在线监测系统仪器信息清单如下:在线监测系统结构为:由采水(浮筒-自吸泵)单元、预处理(沉降-过滤)单元、配水-进样-清洗单元、分析单元、控制单元、压缩空气单元、纯水单元、数据处理与传输单元、数据管理与监控中心系统组成。

电导电极常数精编WORD版

电导电极常数精编WORD版

电导电极常数精编W O R D版IBM system office room 【A0816H-A0912AAAHH-GX8Q8-GNTHHJ8】电导电极的电极常数与盐分的测定方建安(南京传滴仪器设备有限公司)FJA-09型不锈钢电导电极是由塑料支干末端二根不锈钢针和作为温补的2.5K欧的热敏电阻组成,坚固耐用,主要用于湿土壤原位电导率和盐分的测定,也可以用作溶液的电导率和盐分的测定。

一、电导电极常数的测定方法:1、用一定浓度的KCL溶液来校正根据公式K=S/G,电极常数K可以通过测量电导电极在一定浓度的KCL溶液中的电导G来求得,此时KCL溶液的电导率S是已知的。

由于测量溶液的浓度和温度不同,以及测量仪器的精度和频率也不同,电导电极常数K有时会出现较大的误差,使用一段时间后,电极常数也可能会有变化,因此,新购的电导电极,以及使用一段时间后的电导电极,电极常数应重新测量标定。

2、用已知电极常数的电导电极来校正如果有一支已知电极常数的电导电极如K为0.99 ,可以用同一个仪器,同一个溶液分别测定他们的电导率,然后求出电极常数。

如已知电极常数的电导电极测得的电导率为355μS/cm,而未知电极常数的电导电极测得的电导率为340μS/cm,则新电导电极的电极常数为:K=355μS/cm /0.99/340μS/cm =1.055。

二、如何用电导率仪来测定溶液的盐分含量许多用户在购买了普通数字电导率仪后,如何用电导率仪来测定溶液的盐分含量感到有些困难,现将测量的工作原理与测量方法介绍如下,并以DDB-2或DDB-3数字电导率仪为例子。

(一)工作原理1、用电导电极测定溶液电导率时,电导率、电导值和电极常数三者之间的关系为:电导率=电极常数×电导值故只要在进行校正时,将仪器显示值调整到电极常数值,仪器就能直接显示被测电导率。

测定时,只要将仪器所附的温度补偿电极与电导电极一起浸入被测液中,仪器就能进行自动温度补偿。

The space between the boards or cylindres creates a solution collumn, being so the measurement is independent from the total solution volume.The boards or cylindres geomety used will be related to the solutions concentration for a better reading of different samples we vary the distance (and;or) the board section.The relation “distance” (d) over the “section” (s) determines the Cell Constante In order to obtain good results it is necessary to choose the specific cell for the desired application. Three factors are extremelly important in order to choose the right cell: the Electrical, the Mechanical and the chemical.! Electrical! Mechanical! ChemicalWhen reading an electrolyte concentrationof high resistance, caused by low quantity of ions, the greater sensibility will be obtained with bigger electrodes and with a small distance between them. Consequently,we shall diminish the capacitive reatance of the cell-solution system, increasing the polarization tension frequency supplied by the equipment.We will need the inverse when the electrolite is very concentrate: small electrodes with long distances in order to avoid saturation and the polarization effect at the electrodes.The Cell will present low "K" for low conductivity electrolites and high "K" for those of high conductivity,considering that the equipment must have an automatic exchange of the adequate frequency.Some significant factors are: the pressure, temperature, flow speed and the solid suspension presence.only when all these factors are considered that will be achieved a satisfactory performance with a minimum maintenance. When the systems temperature and pressure are higher than the specified values, it must be installed a cooling system with a restraining valve before the cell contact.In places where the flow speed is very low, it must be provided with a flow increase for a solution exchange.solid presence will influence because of obstruction that they can cause at the electrodes or even a super conduction (in metal cases).It is necessary to consider the chemical aggressiveness and clogging caused at the electrodes, this can modify the geometry, altering the constant value.In these cases, the electrodes must be chemically aggressive and must be cleaned periodically.(K) . d s = K .Insertion Cell CDE-440-01Cell Models CDE-440-001, CDE-440-01,CDE-440-1, CDE-440-5 and CDE-440-01T are called Insertion or ImmersionCells.Cell Model CDE-442 is called Toroydal orElectrodeless Cell, as it does not offerelectrodes. The body material could beEpoxy or PTFE, where the Toroydalnucleus (2) are located , indulging anelectromagnetic field, that will generatean electrical current (called FocaultCurrent)proportional to the sampleconcentration. This type of cell isrecommended for high cloggingconcentration and highly chemicallyaggressive.This Cell can only be used withConductivity Analyzer Model# CDCN442. Toroydal Cell CDE-442Based on process conditions, the cells must be build of material previously specified, such as: Stainless Steel 316, Epoxy or PTFE with radial electrodes or SS316 annulars, Platinum, Titanium or others depending on its resistance to the solutions chemical aggressiveness .The electrical connection is done in isolated teminals with ceramic base located at the cast aluminum head,SAE 323, with low oxydation degree, treated against corrosion and finished with electrostatic epoxy paint.The head offers IP-67 protection, allowing the instrumentation cable to go thru by a ½ “NPT threaded holeor a ½ “ cable knockout.Cable KnockoutBefore you install your conductivity cell, please verify for any possible bubbles and if the sample is constantly renewed .1. Prepare the cell installation point in area that offers good stirring, it is preferred to be close to the equipment (maximum of 10 meters -32 feet ) and exempt of vibrations.2. Verify if all threaded points are tied.3. Proceed with the instrumentation cable connection originating from the equipment, going thru the cable knockout of the electrical connection box and connecting it to the interconnection base.ELECTRICAL CONNECTION4. Electrical installation example between the equipment and the ce ll.5. Verify if the cable knockouts are firmly attached to its respective interconnection cables. This is very important so the enclosure still offers IP-67. Sealing is crucial for a perfect performance6. Be careful with humidity! It will diminish the impedance generating measuring errors. Verify the cable press and if necessary, dry the area using a hair dryer.7. Be careful when tying threaded areas, depending on the cable position, it can be cut!Note: Cell model CDE-442 do not offer a connection box and it is necessary a goodinstrumentation cable Sealing only at the equipment, as they do not offer connection cable.a) Do not cut on mend the cell cables!Interconnection CableThis cell type is also connected directly to the equipment connection barr, so cable terminal pin type are used for some equipment cases.Colorless from RedRedBlackColorless from ShieldBlueColorless from BlueInterconnection CableCDE-442 Cell Interconnection21345GreenYellowRed(Anode)(Cathode)N T C CELLEQUIPMENT Am.Vd.Pr.Vm.Blind.Insertion TypeFor a correct conductivity measurement, it is recommended to install the cell as shown on below Illustration.The liquid flow must go thru the Sensor and exit thru the holes located at the upper portion of the sensor.

When under operation, the Conductivity Cell must be maintained periodically (the frequency will depend on the process), which would be basically cleaning, or if necessary, a new calibration.Dip the electrodes in cleaning solution for 40 seconds, then wash throughly with deionized water to avoid standard contamination, when it is time to perform a calibration.Equipments with range of 0 to 200µS or higher.1.
