Current distribution analysis modeled on rebar diameter! A diagnostic device for accurately calculating polarization resistance.
We will mark the measurement locations using a rebar detector. By watering the area before measurement, we will keep the concrete in a moist state, connect the measuring electrode to the exposed rebar, and place the probe directly above the rebar to apply the measurement current to the rebar inside the concrete. This allows us to estimate how the current flows from the counter electrode to the rebar, enabling us to accurately calculate the Rp per unit area. 【Features】 ○ Confirm the rebar arrangement and measure the natural potential: Ecorr, and polarization resistance: Rp' ○ Analyze the apparent Rp' to derive the Rp per unit area and estimate the corrosion amount.
