Resipod
Resipod
The Resipod is the most accurate concrete surface resistivity meter in the world with the highest possible resolution and an efficient all-in-one solution for measuring the electrical resistivity of concrete.It enables measurement in the laboratory but also on site. Its high quality gives you reliable, accurate and standardized results and is faster than laboratory RCP tests. With its waterproof, robust design, you are ideally equipped for use in a wide range of conditions.
Resipod is available in 2 versions:
- with 38 mm (1.5") -> specifically for AASHTO testing to determine resistance to chloride penetration
- with 50 mm probe spacing -> recommended for general concrete testing on site
You can also choose between 2 accessory sets:
Bulk Resistivity
The Bulk Resistivity accessory (volume resistivity measurement) is connected to a Resipod concrete resistivity meter to test concrete surfaces using the Resipod Volume Resistivity (BR) method. Electrical plates with conductive inserts are attached to both ends of a 4 x 8 inch (102 x 203 mm) concrete cylinder and the cables are connected to the meter. The accessory kit consists of test plates, conductive foam inserts and an instrument stand with cable connectors.
Geometric accessories
Geometric accessories
Geometric accessory is an attachment with four probes and a variable probe spacing of 40 to 70 mm, which is connected to a Resipod concrete resistance meter. The adjustable probe spacing is suitable for larger aggregates and a wide range of concrete samples. It can also be connected directly to the meter's ResipodLink software to transfer the measurement data. The Geometric accessory consists of the variable distance probe, a stand to hold the concrete meter and the required cables.

There are two models of Resipod with 38 mm and 50 mm probe spacing. Which one do you recommend for which application?
The 38 mm (1.5") version is specifically designed for AASHTO testing to determine resistance to chloride penetration. For general on-site concrete testing, the 50 mm version is recommended.
Can the surface resistance test be used to measure the corrosion rate?
The surface resistance test cannot accurately measure the corrosion rate. However, it can give an indication of a high or low corrosion rate based on empirically derived values. In principle, a low resistivity corresponds to a high corrosion rate
How does the resistivity affect the measurement of the half-cell potential?
A low resistivity leads to a greater scattering of the negative potentials measured at the surface. A corrosion hotspot is therefore easier to detect. A high resistivity leads to a much narrower spread of the negative potentials measured at the surface, making it easier to overlook a corrosion hotspot.
