Permanent Reference Electrode
Seaguard reference electrode use a special terracotta body with good porosity which guarantees humidity absorption from ground and maintains the copper sulphate solution saturated inside the electrode. It can provide a constant reading even under difficult condition.
The new pipelines with polyethylene coating or similar high dielectric value coating require use of polarization coupon to simulate coating leakage. Seaguard also provides permanent reference electrode with a carbon steel polarization coupon.
Portable Reference Electrode
Seaguard portable reference electrode is ideal measurement equipment to measure surface potentials in industrial environment. It can work with any common used high resistance voltmeter in the field of cathodic protection.
It can be supplied with cable according to customer request.
