DescriptionThe PHE-7352-15 is a combination pH sensor designed for insertable use in process and waste water applications where greater pipeline penetration is required. The outer body material is PPS and has ¾ MNPT front and rear facing threads with 57.1 mm (2¼") insertion depth. The sensor features sealed double junction construction which is highly resistant to electrode poisoning solutions, (typically those with cyanide, ammonia, sulfide and heavy metals in appreciable concentrations). The use of the non-fouling patented Porous PTFE liquid junction ensures a steady presence of reference electrolyte. Coupled with the novel Plunger pH glass electrode design, this sensor assures a low long maintenance service life in most applications. Use of the high temperature version is recommended where service temperatures continuously exceed 80°C (176°F).
