Underwater Corrosion Probes UCP1A & UCP1B Operating Instruction October 2022 English Please read carefully before use

Instruction Manual Description The UCP 1A and 1B contact probes are versatile instruments which are used to carry out under water cathodic potential measurements. The unit is designed for use with manned or remotely operated vehicles (ROVs). There are two types available for use: UCP1A - Contact Probe Operation of the UCP1A is carried out by way of a probe tip making contact with the surface under test, and reading the resulting voltage on a suitable high impedance (> 10M Ohms) or digital voltmeter. The UCP1A has two connections: • Black Wire - Stainless Steel Probe Tip • White Wire -...

Underwater Corrosion Probes Unpacking Remove the UCP from its packaging and check for damage. If any part is damaged, the carrier and supplier should be notified immediately. All packing material should be kept for inspection and the UCP should not be used. The package will contain one of the following items depending on which UCP probe that you purchased: UCP1A – Contact Probe, or UCP1B – Proximity Probe If the probe type is not what you expect please contact your supplier. Maintenance Replacement of electrode Unscrew the two recessed nylon screws on either side of the body. Carefully pull...

Instruction Manual Long Term Storage Flush well in clean seawater to remove any contamination from the Nose Cone and allow to dry. If salt encrustation is seen on the nose cone, remove the Ag/AgCl half-cell and briefly wash in fresh water but immediately after, thoroughly rinse in salt water (3% salinity). Recommissioning Soak the UCP for 2 hours in a seawater solution (3% salinity). Carry out verification checks (see page 7). Calibration There are two types of UCP probe, the 1A ‘Contact Probe’ and the 1B ‘Proximity Probe’.

Underwater Corrosion Probes Both types use the same type of replaceable silver/silver chloride/seawater half-cell. Verification of the Ag/AgCl Half-Cell Plastic container filled with 3% Salinity artificial seawater solution. K-series or K-SAT Reference Electrode. (Use a glass type or plastic screw in with an adaptor) Note 1: Remember to remove the plastic cap on the plastic reference electrode). Note 2: No bare wires should be exposed to the seawater.

Instruction Manual Screw the adaptor lead (6004-0018) onto the reference electrode (plastic screw on type). Submerge the UCP and reference electrode in the 3% seawater solution. Connect the white lead from the UCP to the Positive terminal of the DVM (see Fig. 3 on page 7). Connect the lead from the K-series or K-SAT reference electrode to the negative terminal of the DVM. Allow the electrodes to reach a stable temperature and potential (15 - 30 minutes). The voltage difference between the reference electrode and the internal silver/slver chloride electrode can be read directly off the DVM...

Underwater Corrosion Probes For the UCP1B connect the white lead from the UCP to the positive terminal of the mV meter and negative terminal of the meter to a zinc block. Note: The connection to the zinc block needs to be above the waterline. When the UCP1B is submerged in the water in close proximity to the zinc block the readings will be as shown for the UCP1A above. The UCP1B should also be soaked for 2 hours in the 3% seawater solution prior to taking any measurements. Product Variations The UCP1A is available with varying lengths of underwater cables as follows: Cable Length Part...
