Online Sensors and Controllers: pH & ORP Sensors Combination pH/ORP Sensors Combination pH/ORP Sensors Overview Downloads Accessories Gallery Help These combination sensors are designed for specialty applications for immersion or in-line mounting. The reference cell features a double-junction design for extended service life, and a built-in solution ground. The body is molded from chemically-resistant Ryton® or PVDF, and the reference junction is coaxial porous PTFE. All sensors are rated 0 to 105 ºC up to 100 psig, and have integral 4.5 m (15 ft.) cables with tinned leads. The PC-series (for pH) and RCseries (for ORP) combination sensors are ideal for measuring mild and aggressive media. Sensors with rugged dome electrodes, “easy-to-clean” flat glass electrodes, and even HF (hydrofluoric acid) resistant glass electrodes are available for a wide variety of process solutions. The PC-series combination pH sensors come with or without a Pt 1000 Ohm RTD temperature element. The RC-series combination ORP sensors are supplied without a temperature element. The Sensors are available in three mounting styles - convertible, insertion, and sanitary.
