第3章 電極的選擇與使用
Chapter 3 Selection and use of electrode
根據被測水樣電導率的大小范圍,選擇常數合適的電極是準確測量的關(guān)鍵。特別是對純水(<3μS/cm)和超純水(<1μS/cm)的測量,應用0.1或0.01的電極,必要時(shí)還要加上密閉測量槽,才能作到準確的測量,否則將產(chǎn)生較大的誤差。
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.
選擇電極的基本原則:根據被測水樣電導率的大小范圍,參照下表選擇常數合適的電極。在選擇電極時(shí),*易出現的錯誤是“選擇大常數的電極測低電導”。如選1.0的電極測<3μS/cm的水樣,這不可能得到準確的值。因為低電導介質(zhì)的導電性很差,若再用大常數的電極去測量,則只會(huì )得到更微弱且不穩定的電信號,勢必大幅度增加測量誤差。
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.
DDG-2080配上各種電極后的測量范圍
Measurement Range of DDG-2080 when Equipped with Different Electrodes
測量范圍 Measurement range | 電極常數Electrode constant | 電極型號 Electrode type | 備注 Remarks |
0.01~20μS/cm | 0.01 | DDJ-0.01 | 作流動(dòng)密閉測量 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 |
|
超出上表所列測量范圍進(jìn)行測量時(shí),誤差將會(huì )有所增大。
Nonconformity to the table above will result in increased error.
當介質(zhì)電導率值>100μS/cm時(shí),宜用常數為1.0或10的鉑黑電極測量以增大有效面積,使電極表面的電流密度顯著(zhù)下降,以有效削弱介質(zhì)是濃溶液時(shí)容易產(chǎn)生的電極極化影響。
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.
儀表中設置的電極常數必須與電極上所標的常數一致。如所配電極上標注的電極常數為0.102,則儀表里設置的電極常數必須為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.
