SPCT: Corrosion

SPCT allows the in situ recording of temperature and corrosion potential between a test point (made of an immersed metallic structure) and a measuring electrode in zinc.

 The SPCT is intended for the control of the cathodic protection of fixed or mobile immersed structures, or inaccessible in service: capacities, circuits, pumps, filters, etc.

 It is also intended for the identification of the origin of the corrosion of complex systems (galvanic coupling, leakage current, wandering current, etc.)

 The SPCT also allows the recording of the temperature of the medium.

Features and benefits

  • SPCT allows the in situ recording of temperature and corrosion potential between a test point (made of an immersed metallic structure) and a measuring electrode in zinc.
  • SPCT is designed for monitoring of cathodic protection for submergeed stationary or mobile, or inaccessible structures in service: capacity, circuits, pumps, filters, etc.
  • SPCT is also intended to identify the origin of the corrosion of complex systems (galvanic coupling, leakage current, stray current, etc.)
  • SPCT also allows the recording of the temperature of the environment
