The S88 pH sensors from ECD are one part of the Model S88 Intelligent Sensors product line of sensors for hazardous locations, which include dissolved oxygen sensors, conductivity sensors, and resistivity sensors. They have two universal sensor designs: insertion/submersion or valve retractable with flared end to prevent blowout. The standard S88 sensors have 316 stainless steel housings, although various materials of construction are available to maximize sensor performance while minimizing the cost of ownership.
