Reference Electrode
Introduction
The Ruidesen reference electrode (passed
GB/T19001-2008/ISO9001:2008 certificate of quality management
system cetification, Shenzhen 863 Testing Center test report) is an
ideal buried type reference electrode which has reasonable
structure, reliable performance and long life and used to detect
the cathodic protection potencial of buried steel pipeline and
metallic structure.
Our reference electrodes can be divided into Cu/CuSo4 reference
electrode and high purity zinc reference electrode. Cu/Cuso4
reference electrode including the permanent reference electrode and
portable reference electrode with a wide range applications on
cathodic protection system of buried steel pipeline and metallic
structures.
1. Application scope
(1) ZD series of reference electrodes are used as potential control
source for impressed current cathodic protection system;
(2) ZD series of reference electrodes are used to detect reference
potential of buried pipeline, large tanks, underground fuel tanks,
chemical storage tanks and buried metallic structures;
(3) Cu/CuSo4 reference electrode can be more used in fresh water
type soil enviroment; While high purity zinc reference electrode
can be more used in sea water type soil enviroment.
2. Features
(1) Firm structure, corrosion resistant joints, uniform leakage of
microporous membrane;
(2) Easy to use, the electrode is not prone to polarize, stable
electrode potential.
3. Main technical parameters
3.1 ZD series of Cu/CuSo4 reference electrodes
(1) Electrodecopper material purity99.7%;
(2)Current density flowing through the copper electrode5uA/cm2;
(3)Potential with respect to the standard hydrogen electrode
316mV/25 ℃, potential error5mV.
3.2 ZD series of high purity zinc reference electrodes
(1) As to the Cuso4 electrode potential of -850mV, zinc reference
electrode potential is +250 mV(25℃);
(2) Zinc electrode of the Zinc reference electorde is made from
high pruity zinc, Zinc purity 99.995%.
