Marine Survey Kit

Description
The Marine Survey Kit comprises a weighted silver/silver chloride half-cell,
plastic cable spool and an accurate multimeter. The kit has been specially
created to include all items required to easily carry out a corrosion survey of
marine structures.
The half-cell is housed in a PVC body with holes to allow the easy flow of water
across the cell. The half-cell is weighted to help keep it in position. The cell is
connected to the cable spool by 75m (or a customer-specified length) of CSP
55/015 cable.
Two other leads are supplied to connect the spool and the structure to the
accurate multimeter. In use the multimeter is connected to the structure
(+ terminal) and the cable spool (- terminal).
The half-cell is then lowered into the sea at the desired position. Turning on the
multimeter to the 2V DC voltage range will display the corrosion voltage.

Unpacking
The Marine Survey Kit comprises:
● 1 x Multimeter with operating instructions (Note: copies cannot be supplied)
● 1 x Silver/Silver Chloride weighted half-cell on a cable spool
● 1 x Black lead with a 4mm plug on each end
● 1 x Red lead with a 4mm plug on one end and a crocodile clip on the other

Operation
i. If the half-cell is new or has not been used for a long time it should be
soaked in a plastic bucket of clean seawater for about 2 hours.
ii. It may need longer if the half-cell is very dry.
iii. Turn on the multimeter and check that the battery is OK, see instruction
supplied with meter.
iv. Connect the black lead to the cable spool and to the terminal marked
v. Com (- terminal) on the multimeter.
vi. Connect the red lead with the crocodile clip to the terminal marked ‘V’
vii. (+ terminal) on the multimeter.
viii. Switch the multimeter to the 2 volt (2000mV) DC range (see instructions
supplied with meter).
ix. With the half-cell still in the bucket of seawater put just the tip of the
crocodile clip into the water. The reading on the multimeter should change
from 0.000V to about -0.600V. This shows that the half-cell and multimeter
are working and that the leads are connected correctly.
x. Decide where on the structure the readings are to be taken.
xi. For consistency the reading should be taken in the same place at the same
state of the tide, if applicable, and at the same depth.
xii. This will allow changes to be readily spotted. Always consult a corrosion
engineer to interpret the results.
Surveying
Decide where on the structure the readings are to be taken. For consistency
the reading should be taken in the same place at the same state of the tide, if
applicable, and at the same depth. This will allow changes to be readily
spotted. Always consult a corrosion engineer to interpret the results.
i. Lower the half-cell into the water to the required depth.
ii. Connect the crocodile clip to the structure making sure there is a good
connection.
iii. Switch the multimeter to the 2 volt (2000mV) DC range and the corrosion
potential will be displayed.
iv. Record the location, reading and any other information required. v.
Retrieve the half-cell and disconnect the crocodile clip.
v. Move to the next location and proceed from step 1 again until all the

readings have been taken.
vi. When surveying is complete turn off multimeter and disconnect all leads.
vii. The outside of the half-cell can be dried using a cloth and then be left
to
dry naturally. Do not immerse the half-cell in fresh water as this will cause
viii. the reading to be inaccurate.
Storage
Laying-up
If the Marine Survey Kit is not to be used for a long time, greater than 3 months,
then the following procedure should be used.
i. Unwind the cable from the spool and wash using fresh water to remove
any salt incrustation, then dry using clean cloth. Do not immerse the half-
cell in fresh water.
ii. Wipe the outside of the half-cell casing using a damp cloth and dry. If the
half-cell has been used recently then allow it to dry naturally for 48 hours at
room temperature.
iii. Remove the batteries from the multimeter, see instructions supplied with the
multimeter. Discard the old batteries.
iv. Pack in a cardboard box along with this manual and the multimeter
manual. Do not put the half-cell in a plastic bag.
Re-commissioning
i. Fit new batteries into the multimeter, see instructions supplied.
ii. Check the calibration of the multimeter and if required have it re-
calibrated.
iii. Soak the half-cell in a plastic bucket of clean sea water for about 2 hours. It
may take longer if the half-cell has not been used for a long time.
iv. Connect the black lead to the cable spool and to the terminal marked
‘Com’ (- terminal) on the multimeter.
v. Connect the red lead with the crocodile clip to the terminal marked ‘V’ (+
terminal) on the multimeter.
vi. Switch the multimeter to the 2 volt (2000mV) DC range (see instructions
supplied with meter).
vii. With the half-cell still in the bucket of sea water, put just the tip of the
crocodile clip into the water. The reading on the multimeter should change
from 0.000V to about -0.600V. This shows that the half-cell and multimeter
are working and that the leads are connected correctly.

Calibration
The Multimeter can be checked against another calibrated meter and a 1.5
volt AA battery. Both meters should read the same battery voltage. If not or no
other meter is available then the multimeter should be sent for recalibration.
The half-cell can be checked against a K-SAT reference cell (6004-0111).
Connect the half-cell to the positive terminal of the multimeter and the K-SAT
reference cell to the negative terminal.
With the half-cell in a bucket of clean seawater place the tip of the K series
reference cell into the water. The multimeter should read +54mV ±10mV with a
water temperature of 20°C.
