Differential pH and ORP Sensors

Differential pH and ORP Sensors

Yokogawa differential pH and ORP sensors are specially designed for demanding applications where conventional sensors are not sufficient. These sensors offer high stability and minimal maintenance thanks to a sealed glass reference with no liquid junction or electrolyte in contact with the process.

Differential pH and ORP sensors from Yokogawa are a reliable solution for applications such as brine solutions, electrolysis processes and cheese making. Traditional sensors often suffer from problems such as high diffusion potentials, high temperatures and ground currents. With Yokogawa's advanced design, these challenges are eliminated. The sensor is virtually maintenance-free and offers stable measurement results thanks to its unique cation differential technology. The robust design enables reliable operation even in high temperature and pressure applications.

Features and benefits

  • No fluid junction: Eliminates problems with diffusion potentials and fouling.
  • High stability: No reference elements that can be poisoned or consumed.
  • Robust construction: Withstands temperatures up to 105°C and pressures up to 10 bar.
  • Minimal maintenance: Virtually free from the need for regular cleaning.
  • Versatile use: Adapted for both high temperature and high pressure applications.

Applications

  • Electrolysis processes: High precision pH measurement in chlorinated brine solutions.
  • Food industry: Reliable pH monitoring in cheese production.
  • Chemical industry: Stable pH and ORP monitoring in corrosive environments.
  • Environmental protection: Controlled measurement in wastewater to ensure compliance with environmental requirements.
