UCP1B proximity CP probe


The UCP1B proximity probe is a lightweight and versatile instrument specifically designed to carry out underwater cathodic protection potential measurements. 

The probe has been developed for use with manned or Remotely Operated Vehicles (ROVs) and comes complete with 3 metres of cable. Each probe is supplied with a Certificate of Inspection and Conformity. By placing the UCP1B in close proximity to the surface under test, a voltage reading can be obtained on a suitable high impedance or digital voltmeter. The meter should be connected between the probe and a separate structure negative return.

The UCP1B is extensively used in a wide range of applications including production and drilling platforms, ships’ hulls, jetties and other marine works.
