溶氧分析仪的工作原理

溶氧分析仪的工作原理溶氧分析仪是一种用于测量液体中溶解氧浓度的仪器。

它广泛应用于水质监测、环境保护、水产养殖、生命科学研究等领域。

溶氧分析仪的工作原理主要基于氧气与电极表面发生氧化还原反应的特性。

一般来说，溶氧分析仪由电极系统、测量电路和显示系统组成。

1. 电极系统溶氧分析仪的核心部分是电极系统，它包括溶氧传感器和参比电极。

溶氧传感器通常采用膜型传感器或极谱传感器。

- 膜型传感器：膜型传感器通常由一个氧气透过性良好的膜和一个电极组成。

膜的作用是阻止其他物质进入传感器，只允许溶解在液体中的氧气通过。

当氧气通过膜进入传感器时，它与电极上的还原剂发生反应，产生电流信号。

根据电流信号的大小，可以推算出液体中的溶解氧浓度。

- 极谱传感器：极谱传感器通过测量氧气与电极表面的氧化还原反应电流来确定溶解氧浓度。

它通常由一个工作电极和一个参比电极组成。

工作电极上涂有一个催化剂，用于促进氧气的还原反应。

参比电极用于提供稳定的电势参考。

2. 测量电路溶氧分析仪的测量电路用于接收和处理电极系统传输的电流信号。

它通常包括放大器、滤波器和模数转换器等组件。

- 放大器：放大器用于放大电极系统传输的微弱电流信号，以便更准确地测量溶解氧浓度。

- 滤波器：滤波器用于滤除电磁干扰和其他杂散信号，确保测量结果的准确性和稳定性。

- 模数转换器：模数转换器将模拟信号转换为数字信号，以便后续处理和显示。

3. 显示系统溶氧分析仪的显示系统用于显示测量结果。

它通常由液晶显示屏、控制按钮和数据处理芯片等组件组成。

- 液晶显示屏：液晶显示屏用于显示溶解氧浓度值和其他相关信息，如温度、时间等。

- 控制按钮：控制按钮用于设置分析仪的参数，如校准、单位选择等。

- 数据处理芯片：数据处理芯片用于处理和存储测量数据，提供数据分析和导出功能。

溶氧分析仪的工作原理基于电极系统的氧化还原反应和测量电路的信号处理。

通过正确操作和校准，溶氧分析仪可以提供准确、可靠的溶解氧浓度测量结果，帮助用户监测和控制液体中的溶解氧含量，保证水质和环境的安全与稳定。

溶解氧传感器工作原理

溶解氧传感器工作原理
溶解氧传感器的工作原理如下：
1. 溶解氧传感器是一种用于测量液体中溶解氧浓度的传感器。

它通常由两个电极组成：阳极和阴极。

2. 阳极通常是一根银棒，而阴极则是由铂制成的线丝。

3. 在传感器工作时，阳极和阴极浸入待测液体中。

4. 当液体中存在溶解氧时，氧气分子会在阴极表面还原成氢离子。

5. 阳极则会接受这些氢离子，并将其氧化成水。

6. 在阳极和阴极之间，会形成一个电流，其强度与液体中溶解氧浓度成正比。

7. 通过测量这个电流，可以确定液体中的溶解氧浓度。

8. 通常情况下，溶解氧传感器会和温度传感器结合在一起，以补偿温度对溶解氧测量的影响。

总的来说，溶解氧传感器通过测量液体中溶解氧引起的电流变化，来确定液体中的溶解氧浓度。

氧分析仪的工作原理

氧分析仪的工作原理氧分析仪的工作原理在现在的工业环境中，氧气的含量对工业生产有着重要的作用，因此经常对其测量。

仪器市场上的产品多种多样，但是就测量原理来分，主要有2中测量方法：（1）热磁式氧分析仪其原理是利用烟气组分中氧气的磁化率特别高这一物理特性来测定烟气中含氧量。

氧气为顺磁性气体（气体能被磁场所吸引的称为顺磁性气体），在不均匀磁场中受到吸引而流向磁场较强处。

在该处设有加热丝，使此处氧的温度升高而磁化率下降，因而磁场吸引力减小，受后面磁化率较高的未被加热的氧气分子推挤而排出磁场，由此造成“热磁对流”或“磁风”现象。

在一定的气样压力、温度和流量下，通过测量磁风大小就可测得气样中氧气含量。

由于热敏元件（铂丝）既作为不平衡电桥的两个桥臂电阻，又作为加热电阻丝，在磁风的作用下出现温度梯度，即进气侧桥臂的温度低于出气侧桥臂的温度。

不平衡电桥将随着气样中氧气含量的不同，输出相应的电压值。

（2）氧化锆传感器式氧分析仪氧化锆（ZrO2）是一种陶瓷，一种具有离子导电性质的固体。

在常温下为单斜晶体，当温度升高到1150℃时，晶型转变为立方晶体，同时约有7%的体积收缩；当温度降低时，又变为单斜晶体。

若反复加热与冷却，ZrO2就会破裂。

因此，纯净的ZrO2不能用作测量元件。

如果在ZrO2中加入一定量的氧化钙（CaO）或氧化钇（Y2O3）作稳定剂，再经过高温焙烧，则变为稳定的氧化锆材料，这时，四价的锆被二价的钙或三价的钇置换，同时产生氧离子空穴，所以ZrO2属于阴离子固体电解质。

ZrO2主要通过空穴的运动而导电，当温度达到600℃以上时，ZrO2就变为良好的氧离子导体。

氧分析仪，该产品重量轻，所以携带方便，小功率操作（GPR-1100充电一次可连续操作30天，超过8小时的内部泵运行），并可测量小于10ppm的氧含量。

使用过程中，用户喜欢简单直观的操作，搭配一个坚固的外壳，防止重工业环境下的意外损坏。

为了最大限度的提高氧分析仪寿命，的结构中有一个快速连接件，用来保护仪器不工作时传感器暴露在空气中所带来的损坏，这样传感器寿命可达用户所期望的24个月。

溶解氧测试仪的原理

溶解氧测试仪的原理在污水处理过程中，通过增加污水中的氧含量使污染物通过活化泥浆被分解出来，达到污水净化的目的，测量氧含量有助于确定最佳的净化方法和最经济的曝气池配置。

在生物发酵过程中氧含量的测量数据可对工艺过程进行指导，如判断发酵过程的临界氧浓度、发酵罐的供氧能力以及菌体的活性和菌体的生长量等，并根据发酵时的供氧和需氧变化来指导补料操作。

一、溶解氧分析仪测量原理氧在水中的溶解度取决于温度、压力和水中溶解的盐。

溶解氧分析仪传感部分是由金电极(阴极)和银电极(阳极)及氯化钾或氢氧化钾电解液组成，氧通过膜扩散进入电解液与金电极和银电极构成测量回路。

当给溶解氧分析仪电极加上0.6～0.8V 的极化电压时，氧通过膜扩散，阴极释放电子，阳极接受电子，产生电流，整个反应过程为：阳极Ag+Cl→AgCl+2e- 阴极O2+2H2O+4e→4OH- 根据法拉第定律：流过溶解氧分析仪电极的电流和氧分压成正比，在温度不变的情况下电流和氧浓度之间呈线性关系。

二、溶解氧含量的表示方法溶解氧含量有3 种不同的表示方法：氧分压(mmHg)；百分饱和度(%)；氧浓度(mg/L 或10-6)，这3 种方法本质上没什么不同。

(1)分压表示法：氧分压表示法是最基本和最本质的表示法。

根据Henry 定律可得，P=(Po2+P H2O )×0.209，其中，P 为总压；Po2 为氧分压(mmHg)；P H2O 为水蒸气分压；0.209 为空气中氧的含量。

(2)百分饱和度表示法：由于曝气发酵十分复杂，氧分压不能计算得到，在此情况下用百分饱和度的表示法是最合适的。

例如将标定时溶解氧定为100％，零氧时为0％，则反应过程中的溶解氧含量即为标定时的百分数。

(3)氧浓度表示法：根据Henry 定律可知氧浓度与其分压成正比，即：C=Po2 ×a，其中C 为氧浓度(mg/L)；Po2 为氧分压(mmHg)；a 为溶解度系数(mg/mmHg·L)。

微量溶解氧分析仪

微量溶解氧分析仪概述微量溶解氧分析仪是一种用于测量水体中微量溶解氧浓度的仪器。

微量溶解氧分析仪通常使用电极引入空气氧对水体中的溶解氧进行氧化还原反应，并根据反应的程度来计算水体中的溶解氧浓度。

微量溶解氧分析仪广泛应用于生物、环境、医学等领域的实验室研究以及工业生产中的监测。

它可以帮助研究人员了解水体中溶解氧含量的变化，以及环境中的氧气供应能力和水质状况。

工作原理微量溶解氧分析仪使用一种叫做极谱分析的技术。

这种技术利用电化学原理，在水中引入氧气和电荷，并测量氧气和电荷之间的电位差。

这个电位差的大小可以衡量水体中的溶解氧浓度。

在溶解氧传感器内，有一个叫做极板的金属板。

当极板接触水时，引入的氧气会在极板上氧化，而极板释放的电子会反应到另一个叫做参比电极的金属板上。

这种反应会导致参比电极上的电荷发生变化。

根据这个原理，微量溶解氧分析仪通过测量极板和参比电极之间的电位差来测量水体中溶解氧的浓度。

应用微量溶解氧分析仪广泛应用于以下几个领域：生物学研究微量溶解氧分析仪是生物学研究中不可或缺的工具。

它可以帮助生物学家研究生物体在低氧环境下的生理反应，进而了解人类和其他动物在缺氧条件下的生理状况。

微量溶解氧分析仪还可以被用于研究海洋生物和水生动物对气体变化的适应能力。

环境监测微量溶解氧分析仪可以被用于监测环境中水体的溶解氧含量。

这可以帮助环境科学家了解水体中氧气的供应能力以及水质的状况。

微量溶解氧分析仪还可以被用于监测水体中的微生物生长，因为微生物需要氧气来生长。

工业监测微量溶解氧分析仪可以被用于工业场所中的监测。

例如，在水处理厂中，微量溶解氧分析仪可以被用于监测处理过程中的水质，以确保水质符合标准。

微量溶解氧分析仪还可以被用于监测工业生产过程中的废水和污水。

总结微量溶解氧分析仪是一种用于测量水体中微量溶解氧浓度的仪器。

它利用电化学原理，在水中引入氧气进行氧化还原反应，并测量氧气和电荷之间的电位差，从而计算溶解氧浓度。

溶解氧分析仪相关技术参数

溶解氧分析仪相关技术参数溶解氧分析仪是一种用于测定水体中溶解氧含量的仪器。

它通常采用电化学法，通过测量电极在水中的极化电势来计算溶解氧含量。

以下是溶解氧分析仪的相关技术参数：测量范围溶解氧分析仪的测量范围通常为0-20mg/L。

为了优化测量效果，在这个范围内可以进行更细致的分区。

常见的分区方式是将整个测量范围分为五个小区间，分别是0-2mg/L、2-4mg/L、4-6mg/L、6-10mg/L和10-20mg/L。

这样可以更准确地测量不同浓度的水样。

精度溶解氧分析仪的精度通常标注为±0.1mg/L。

这意味着，当测量结果为10mg/L 时，实际溶解氧含量可能在9.9mg/L到10.1mg/L之间。

通常情况下，提高测量精度需要使用更先进的仪器和更精准的校准标准物质。

响应时间响应时间是指半仪器响应到达最大响应的时间。

具体响应时间取决于不同的设备，通常在60秒至5分钟之间。

较短的响应时间能更快地获取测量结果，但可能会使测量精度降低。

校准溶解氧分析仪通常需要定期进行校准。

标准溶液是用于校准的标准物质。

通常使用两种或更多的标准物质进行多点校准，以确保仪器准确性。

一般情况下，校准建议在每次使用前进行。

温度补偿溶解氧的浓度与水温密切相关，故需要对温度进行补偿。

温度补偿通常表现为一个可调节的参数，使仪器在不同温度下得到更准确的测量结果。

在实际应用中，温度会对测量结果产生较大的影响，必须选择适当的补偿参数。

自动清洗由于仪器常用于长时间、高浓度的水样测量，因此有时需要自动清洗以确保测量精度。

自动清洗可以定期定量清洗，避免出现瓶颈、附着物等问题，保证仪器的长期可靠性。

数据管理数据管理通常表现为软件程序或内置的存储器，以便于用户跟踪、分析和管理测量数据。

在现代仪器中，一些软件程序能直接将数据传输至计算机，便于用户进行统计和分析。

总之，溶解氧分析仪的技术参数及其应用都需要有更多的了解和认识。

在实际应用中，针对不同的需求和具体应用场景，需要有选择和分析的手段以确保测量结果的准确性和可靠性。

3.1氧传感器氧传感器称氧电极。

电极的阴极由Φ4mm黄金片组成，阳极即参比电极为银电极，两极的空间充入电解液，顶端被聚四氟烯薄膜复盖；当在金极与银极间加0.7伏左右极化电压后，渗透过薄膜的氧在黄金阴极上还原产生如下反应：阴极：O2+2H2O+4e→4OH-(1)银阳极发生的反应如下：阳极：4Ag++4Cl--4e→4AgCl(2)由于电极上发生氧化－还原反应，电子转移产生了正比于样品中氧分压的电流。

无氧时，氧电极中没有电流，有氧时，电流大小可用下列公式表示：Pml＝K?N?F?A----?Cs(3)dm式中：K：为常数；N：反应过程中得失电子数F：为法拉第常数Pm：为薄膜的渗透系数；dm：为薄膜的厚度；A：为阴极面积；Cs：为样品中的氧分压；l：为扩散电流。

当电极结构固定。

阴极面积一定。

薄膜的种类与厚度一定。

A.Pm.dm均为常数，此时式(3)变为：i＝k?Cs(4)式(4)表明，在一定温度下，扩散电流的大小与样品中氧分压成正比例关系。

测得电流值的大小，便可知样品中氧浓度。

仪器用已知溶解氧浓度的标准样品校准至跨度后，使可以直接读出被测样品中溶解氧浓度。

Underconstant conditions, this flow is proportional to the oxygen content of the medium.This current is converted in the transmitter and indicated on the display as an oxygen concentration in mg/l,as a saturation index in % SAT or as an oxygen partial pressure in hPa.Memosens technology Maximum process safetyThe inductive and non-contacting measured value transmission of Memosens guarantees maximum processsafety and offers the following benefits:•All problems caused by moisture are eliminated.–The plug-in connection is free from corrosion.–Measured value distortion from moisture is not possible.–The plug-in system can even be connected under water.•The transmitter is galvanically decoupled from the medium. The result: No more need to ask about"symmetrically high-impedance" or "unsymmetrical" (for pH/ORP measurement) or an impedanceconverter.•EMC safety is guaranteed by screening measures for the digital measured value transmission.•Application in explosion-hazardous areas is unproblematic; the integrated electronics are intrinsically safe.Data safety through digital data transferThe Memosens technology digitalizes the measured values in the sensor and transfers them to the transmittercontactlessly and free from interference potential. The result:•An automatic error message is generated if the sensor fails or the connection between sensor and transmitteris interrupted.•The availability of the measuring point is dramatically increased by immediate error detection.Easy handlingSensors with Memosens technology have integrated electronics that allow for saving calibration data andfurther information such as total hours of operation and operating hours under extreme measuring conditions.When the sensor is mounted, the calibration data are automatically transferred to the transmitter and used tocalculate the current measured value. Storing the calibration data in the sensor allows for calibration away fromthe measuring point. The result:•Sensors can be calibrated under optimum external conditions in the measuring lab. Wind and weather doneither affect the calibration quality nor the operator.•The measuring point availability is dramatically increased by the quick and easy replacement of precalibratedsensors.•The transmitter does not need to be installed close to the measuring point but can be placed in the controlroom.•Maintenance intervals can be defined based on all stored sensor load and calibration data and predictivemaintenance is possible.•The sensor history can be documented on external data carriers and evaluation programs at any time.

光学溶解氧测量仪

光学溶解氧测量仪简介光学溶解氧测量仪是一种用于水体中氧气浓度测量的设备。

它是一种非侵入式的测量方法，可以在不破坏水体结构的前提下，直接对水体中溶解氧浓度进行测量。

在水体的环境监测、水产养殖、污水处理等领域有广泛的应用。

工作原理光学溶解氧测量仪的工作原理是基于光的吸收和荧光发射原理。

测量前先将水体中的氧气分子与内置的荧光物质分子进行非常强烈的作用，使荧光物质分子激发成为激发态，然后再制造一个吸收和发射荧光的光源，通过测量吸收和发射荧光的光能量和时延可以得到波长与氧气浓度的关系。

通过这个关系，就能够计算出在特定条件下的溶解氧浓度。

特点光学溶解氧测量仪具有以下特点：1.非侵入式：与传统的电化学方法不同，光学溶解氧测量仪不会破坏水体结构，对水体造成一定影响，并且取样的过程也简便。

2.高精度：光学溶解氧测量仪可以提供高度精确的数据，可以测量低至0.1mg/L的溶解氧。

3.稳定性高：光学溶解氧测量仪具有高稳定性和高重复性，可以在较长时间内大量连续测量，可以满足长时间的自动化监测需求。

4.易于使用：光学溶解氧测量仪操作简便，不需要特殊的专业技能，几乎所有人都可以学会如何使用。

应用领域光学溶解氧测量仪在以下领域中得到了广泛应用：1.污水处理：在污水处理过程中，正确的溶解氧浓度可以帮助优化好氧和缺氧处理过程，光学溶解氧测量仪可以提供必要的数据来帮助优化污水处理过程。

2.水体环境监测：水体环境监测是开展水体保护和管理的一项重要工作。

光学溶解氧测量仪可以为环境监测机构提供重要的溶解氧数据来评估水体健康状况和鱼类动物生态系统的保护和管理。

3.水产养殖：水产养殖中氧气供应是至关重要的，过低或过高的氧气浓度会影响水产物的健康和生长。

光学溶解氧测量仪可以提供必要的溶解氧数据来衡量和优化水体中的氧气供应。

总结光学溶解氧测量仪是一项简便而高效的水体环境监测工具，可以提供高度精确的氧气浓度数据，适用范围广泛。

在水体的保护和管理以及水产养殖等应用领域有广泛的应用前景。
