The METTLER TOLEDO Thornton Optical Dissolved Oxygen Sensor for Pure Water Applications with ISM Technology has been developed specifically for demanding applications in the energy and microelectronics industries. Optical measurement technology and low maintenance requirements ensure the highest measurement accuracy, stability and responsiveness. Together with the M800 multi-parameter transmitter, the system provides outstanding performance and reliability.

Applications

  • Monitoring the chemical cycle of the power plant
  • Generator stator cooling
  • Analysis of ultrapure water in the microelectronics industry
  • Water treatment systems

Features and benefits

  • High precision, immediate response and improved stability in low concentration applications.
  • Low detection limit, minimal drift and short response time improve oxygen monitoring.
  • Response speed is 33% faster than competitive models.
  • The company's OptoCap measuring element is distinguished by its high measurement accuracy and simple maintenance without the need for electrolyte electrolyte.(?)
  • The OptoCap element eliminates the need to use polarization, which increases the reliability of the measurement system and reduces downtime.
  • ISM technology enables preventive maintenance through predictive diagnostics tools.
