■ Overview
Selecting the proper pH electrode for an application can be a challenging exercise.
The heart of a pH measuring loop is the electrodes. Yokogawa has designed a wide range of electrodes to ensure this heart keeps beating under the most severe conditions.
A high degree of standardization makes it possible to mount any electrode in the standard program of f ittings.
The combination of electrode plug and cable socket is watertight and temperature is resistant up to 130ºC.
Colour-coded strips on electrodes and cables and clear identification of sensor specifications make incorrect inst allation virtually impossible.
■ Features
- Dome-shaped membrane for “Heavy Duty”applications.
- Wide range of electrodes to suit almost all process conditions.
- Colour code strips for easy identification of electrodes and cables.
- High degree of standardization for mounting in various flow,insertion- and immersion fittings.
- Separate electrode system for high accuracy applications.
- Reference sensors with a junction made of ceramic, PTFE, pNa glass or Zirconium.
- Combination electrode with external liquid earth.
The SC21 series, Yokogawa’s trusted range of combination pH electrodes for many years still have the same variety of options, making it easy to find the best electrode for each application.
