FAQ
How does Profometer Corrosion PM8500 work?

The Profometer Corrosion PM8500 is based on a technology called "Half Cell Potential". It works by measuring the electrochemical potential difference between a reference electrode and a rebar embedded in the concrete. This...

What are the benefits of using Profometer Corrosion PM8500?

Using the PM8500 provides fast and accurate information about the corrosion potential of reinforced concrete structures. It can help you save money by identifying and mitigating corrosion damage before it becomes...

See More
What are the advantages of using Half Cell Potential to measure concrete corrosion probability?

Some advantages of using Half Cell Potential to measure concrete corrosion probability are:

  • Non-destructive test: Only a ground cable needs to be connected to a rebar, the electrical continuity of the rebar mesh needs...
See More
What is the sampling rate of the Profometer PM8500?

The sampling rate of the Profometer PM8500 is 900Hz.

How is the reference electrode selected for use in a half cell potential corrosion tester?

The reference electrode used in a half cell potential corrosion tester is selected based on the specific application and environment being tested. The PM8500 includes a copper/copper (Cu/CuSO4) reference electrode, but...

See More
What factors can affect the accuracy of a half cell potential corrosion test?

Factors that can affect the accuracy of a half cell potential corrosion test include the selection of the reference electrode, the quality of the electrolyte solution, the preparation of the concrete surface being tested,...

See More
How do moisture and temperature affects the readings?

Moisture can have a large effect of the measured potential leading to more negative values. High temperature causes concrete resistivity to be lower, which leads to more negative potentials, while low temperature causes...

See More
How does the concrete cover influence the corrosion inspection results?

The potential becomes more positive with increasing concrete cover. Very low concrete cover can lead to more negative potentials, which may indicate higher levels of corrosion. It is recommended to measure the concrete...

See More
How do I connect to a rebar?

We always recommend using Profometer PM8000 or GP8x00 to locate the rebar. Once the rebar is located, drill the concrete cover and connect the ground cable to it. The connection should be tested for electrical continuity,...

See More
Do I need to pre-wet the concrete surface before the testing?

The contact between the pore solution of the concrete and the probe can be impaired by a dried out concrete skin. This can greatly increase the electrical resistivity of the concrete.

It is recommended to moisten the...
