Cu/CUSO4 Permanent Reference Electrodes -CSE

الوصف

~Copper Sulfate half-cell (CSE) is the most commonly used reference electrode in Cathodic Protection corrosion control systems.
 CSE use the redox reaction between a pure copper coil immersed in a saturated solution of copper sulfate CuSO4 to obtain a highly stable and well-known electrode potential.
For these reasons, CSE half-cells are widely used as reference electrodes for measuring the electrical potential of buried or immersed structures in respect of the surrounding electrolyte.

 Our standard CSE fixed reference electrodes is manufactured in **0 x **0 mm (Hxø) dimensions and come with 5 m 1x6 mm2 double insulated HEPR/PVC cable, but various size, cables type, length and connection system can be produced according customers requirements.
In case of highly-insulated structures to be monitored, e.g. new tri-layer polyethylene coated pipelines, our fixed CSE reference electrodes can be manufactured with included carbon steel corrosion coupon and 2 x 4 mm2 HEPR/PVC cable to simulate coating defects.

For small structures like underground gas or fuel tanks, we can supply a small and reliable CSE electrode that can be refilled with high purity copper sulfate to extend lifetime.

For installation in very dry and high resistivity soils, electrodes come pre-packaged in gypsum-bentonite backfill to ensure superior and long lasting humidity retention.
Fixed CSE reference electrodes must be installed in vertical position at a maximum distance of ****0 cm from the structure to me monitored. Prior to installation, ensure humidity absorption by soaking the electrode in fresh water for at least *4 hours.
