Series WDP400 accepts two electrode signals in any combination of pH and ORP. Offered in a prewired NEMA 4X wall-mount package, the dual-input model reduces space requirements. Integrated datalogging can be used to validate system performance. Data and event logs such as electrode measurements, temperature, accumulated chemical feed and relay activation times can be extracted from the controller using a USB drive.
