Emerson Rosemount 0399-02-11151-00-H95 PH ORP Sensor

Emerson Rosemount 0399-02-11151-00-H95 pH/ORP Sensor is a general-purpose Rosemount pH and ORP sensing head designed for inline process measurement in pipelines, open tanks, or ponds. Its TeFzel housing, glass reference, and Viton seals deliver chemical resistance in harsh aqueous environments, and it uses a 1-inch MNPT process connection with a weight of about 0.45 kg, rated up to 100 psig at 65°C. The sensor provides pH measurement from 0 to 14 and ORP from -1500 to +1500 mV, with automatic temperature compensation from 0 to 85°C to maintain accuracy across process temperatures. Interconnecting cable is five-conductor and available in 10- or 32-foot lengths with an integral preamp option, enabling reliable connection to Rosemount transmitters and control systems.
