3.1.3 Factors affecting the potential measurement Provided that the corrosion conditions are equal (chloride content or carbonation of the concrete at the steel surface) the main influences upon the half-cell potentials are: 25.

4.1.7 How to mount the sensor on the harness PM8500 includes a chest harness to carry the iPad, helping the user for free hands operation. This harness is also very useful to carry the sensor unit when using the rod electrode. To do so, you can use the universal holder, and connect the inner clamp to the harness belt. -

Wheel spacing set up 4.1.11 Coated surfaces It is not possible to make a measurement through an electrically isolating coating (e.g. an epoxy resin coating, sealing sheets or asphalt layers.) It is possible to make a measurement through thin dispersion coatings, that are often used, for example on the walls and ceiling of underground car parks, however this can cause a small shift of the potentials. -

This is only possible with the Rod Electrode. Proceq provides an additional sponge that connects to the rod electrode to increase the overall surface contact area, to prevent testing immediately above a large aggregate. - Page 23 Once the app is downloaded, user needs to create a Screening Eagle account.

3. Connect either the rod or the wheel electrode to the Electrode - Input (blue cable). 4. Put both probes together to close the electrical circuit. Recommendation for wheel electrodes: measure direct on the wooden spigot (copper sulphate side). 25.
