The core part of the pH measurement circuit is the electrode system. Yokogawa has developed widely used electrodes to ensure normal operation even under harsh conditions. The size and design meet the requirements of DIN 19263 (excluding refillable types).
High standardization enables any electrode to be installed in standard devices

The electrode plug and cable socket have good water tightness and can withstand temperatures up to 125 ℃, meeting the IP65 standard. The color coded bands on the electrodes and cables, along with clear sensor specifications, greatly reduce the possibility of incorrect installation.

• Widely applicable electrodes can be used for almost all process controls.
  
• The connecting components are gold-plated, ensuring good conductivity even under harsh conditions.
  
• The electrode plug and cable socket are designed to be waterproof and comply with IP65 standards.
  
• It is very easy to distinguish electrodes from cables using color coded bands.
  
• Highly standardized, suitable for various flow fitting, plug-in, and immersion devices.
