The Aquamate™ Linear Polarization Resistance is your best answer to the problem of getting quick and easy corrosion rate measurements in water systems. Simply plug the hand‐held instrument into a LRP probe and press the measure key. In a few minutes the readout will display the corrosion rate in mils per year (MPY), the imbalance reading, conductivity, and, if you're using a LPR Temperature probe, the water temperature.
