Adwa’s ORP electrodes are interchangeable and no mV calibration is needed when they are replaced. If measurements are not accurate, a mV recalibration should be performed. For an accurate recalibration, contact your dealer or the nearest Adwa Customer Service Center, or follow the instructions below.
