Reference Electrode

    Reference Electrode is one of the important parts of cathodic protection (CP) system.

    It can be used to measure the potential of the protected structure and can also be used as a 

signal source for automatic control of the Transformer Rectifier. Reference Electrodes are made 

of Copper Sulfate, Silver Chloride and Antimony, which used as a half cell to build an

electrochemical cell.

   Jinhongtai supplies Portable Reference Electrodes and Permanent Reference Electrodes.

Portable Reference Electrode

    Portable Reference Electrode usually has a light weight which increases flexibility while at the 

same time maintaining quality performance and portability, easy to load and carry. 

    They are suit for soil and seawater engineering, fully consistent with the national standard 

GB / T7387-1999 " 

Characteristics of the Portable Reference Electrode

  -They have porous ceramic test head, which can decrease soil impedance and be easily inserted 

in soil;

-Suit for soil and aqueous solution;

-Best reliability;

-Easily schlep and use;

-Clarity window makes you become conscious of the liquor remainder

 Permanent Reference Electrode

    Permanent Reference Electrode is designed for 40 years life, but it usually lasted for 20 years 

according to the engineering practices. The Permanent Reference Electrode applicant to bury in 

soil,and we recommend Ag/AgCl electrodes to be used in chloride ion contaminated soil

Applications of the Permanent Reference Electrode

-It can accurate monitoring the CP status and measure the sacrificial anode’s potential; 

-It acts as auto control stable signal source in impressed current CP system;

-It can be planted in the bottom of tanks or under the roads;

-It can be pre-buried during the engineering and be used at a long time
