SC21 Electrode for pH/Redox (Flow)

Brand: Yokogawa Electric Corporation

This flowing electrolyte sensors uses a ceramic reference junction, with the electrolyte (3.3 molal KCl). 

The flow of electrolyte through the junction, while small, remains the safest way to prevent clogging and to protect the internal reference against poisoning and diffusion.
Features
  • For tough application where pollution of the reference system is to be expected
  • Low ionic application where the possitive flow of electrolyte provides the conductivity needed to measure pH (<50 μS/cm)
  • Heavy duty pH sensitive glass
  • Flowing reference system for pollution resistance, and highly stable reference potential
  • PG13.5 standard DIN electrode connection
  • Adapter to ensure compatibility with full fitting program
  • Use in combination with the presurisable electrolyte reservoir to obtain a positive flow towards the process (K1500YA)
