第3章 电极的选择与使用
Chapter 3 Selection and use of electrode
根据被测水样电导率的大小范围,选择常数合适的电极是准确测量的关键。特别是对纯水(<3μS/cm)和超纯水(<1μS/cm)的测量,应用0.1或0.01的电极,必要时还要加上密闭测量槽,才能作到准确的测量,否则将产生较大的误差。
It is key for accurate measurement to select an electrode with suitable constant according to the conductivity range of the tested water. Especially, for accurate measurement of pure water (<3μS/cm) and hyperpure water (<1μS/cm), an electrode of 0.1 or 0.01 should be used, and closed measurement tank should be equipped when necessary.
选择电极的基本原则:根据被测水样电导率的大小范围,参照下表选择常数合适的电极。在选择电极时,*易出现的错误是“选择大常数的电极测低电导”。如选1.0的电极测<3μS/cm的水样,这不可能得到准确的值。因为低电导介质的导电性很差,若再用大常数的电极去测量,则只会得到更微弱且不稳定的电信号,势必大幅度增加测量误差。
Basic principles for electrode selection: An electrode with suitable constant should be selected according to the conductivity range of the tested water with reference to the table below. When selecting an electrode, a common mistake is “using an electrode of relatively higher constant for measurement of low conductivity”. For example, if electrode of 1.0 is used to measure the conductivity of <3μS/cm water, accurate measurement cannot be obtained. This is because that the low conductivity tested medium together with high constant electrode will lead to weak and unstable electric signal and thus greatly increase the measurement error.

Measurement Range of DDG-2080 when Equipped with Different Electrodes
测量范围 Measurement range | 电极常数Electrode constant | 电极型号 Electrode type | 备注 Remarks |
0.01~20μS/cm | 0.01 | DDJ-0.01 | 作流动密闭测量 Closed measurement of flowing liquid |
0.1~200μS/cm | 0.1 | DDJ -0.10 |
|
1~2000μS/cm | 1.0 | DDJ -1.00 |
|
10~20000μS/cm | 10 | DDJ -10.0 |
|
30~600.0mS/cm | 30 | DDJ -30.0 |
|
超出上表所列测量范围进行测量时,误差将会有所增大。
Nonconformity to the table above will result in increased error.
当介质电导率值>100μS/cm时,宜用常数为1.0或10的铂黑电极测量以增大有效面积,使电极表面的电流密度显著下降,以有效削弱介质是浓溶液时容易产生的电极极化影响。
When the conductivity is above100μS/cm, platinum black electrode with a constant of 1.0 or 10 is recommended to increase the effective area, remarkably decrease the current density on the surface of electrode and thus effectively reduce the impact of electrode polarization that generally occurs when the medium is solution.
仪表中设置的电极常数必须与电极上所标的常数一致。如所配电极上标注的电极常数为0.102,则仪表里设置的电极常数必须为0.102。
The electrode constant set in the instrument must be the same as the constant marked on the electrode. For example, it the electrode used indicates a constant of 0.102, then the parameter of electrode constant in the instrument must be set to 0.102.
