tube. Upper rubber sleeve is used to protect electrode, Q9 socket
transmit electricity. Unscrew the upper rubber sleeve and
Q9socket, and inject copper sulfate solution into the electrode.
While used, firstly remove bottom rubber sleeve and then remove
the upper rubber sleeve (one end of Q9): that is to hold upper
rubber sleeve of copper sulfate electrode and PMMA tube with
two hands, rotating rubber sleeve clockwise and separating
electrode upper and PMMA tube. Placing 20 grams copper
sulfate into PMMA tube and pouring about 4/5 distilled water to
PMMA tube and equipping upper part of electrode to PMMA
tube. Shaking electrode appropriately, making copper sulfate
solution reaches saturation, small amount of copper sulfate
particle exists.
2. To install bottom bracket of electrode,
Firstly soak sponge with distilled water, when soften completely,
screwing to the electrode bottom, at the same time, keep a good
contact between sponge and bottom white ceramic chip. The
electrode installed for use is shown in fig.4-3b.
Attention: the electrode can use sustainable after
one time mixing liquid until the remaining liquid inadequate
then reequipped with liquid or supplemented.
4.2.1.2 To determine survey area
It is better to select area of structural concrete with rebar
corrosion signs or possibility of corrosion, the area should be less
than 5m×5m.
4.2.1.3 To distribute measuring points
1.
Distributing measuring lines on the surface of object to be tested,
measuring lines in X direction and Y direction constitutes a square
grid, see fig.4-4 and fig.4-5. The crossing point of measuring lines is
the measuring points. Generally, space of single-electrode measuring
points is set to 10cm
～
50cm. Space of double-electrode measuring
