The low-maintenance, low cost-of-ownership S8000 pH/ORP platform combines a next-generation, flat-surface, self-cleaning pH/ORP (REDOX) sensor with modular mounting hardware and optional electronics to deliver precise measurement, while reducing costs for water/wastewater treatment applications. It is fully configurable. The S8000 sensor electrode measures a pH range from 0 to 14 (0 to 12.3 pH with low Na+ ion error) at a pressure range of 0 psig to 100 psig de-rated under temperature.
