Yokogawa’s line of pH sensors has been strengthened by the inclusion of the polymer electrolyte pH sensor PH4P/PH4PT, HF-resistant pH sensor PH4F/PH4FT, pH sensor for chemical process PH4C /PH4CT, and pH sensor for fermentation PH4FE. 

Like the pH sensor series, the ORP sensor series is also offered as a complete lineup with the polymer electrolyte ORP sensor OR4P, ORP sensors for chemical process OR4C in addition to standard Ryton pH/ORP sensors.
Features
  • Allows ORP measurement under severe conditions, such as where the process fluid is heavily contaminated or contains sulfide.
  • With polymer used as the inner solution, the liquid junction is large (1.0 mm to 1.5 mm), and there are 2 single pores, which prevent clogging.
