The Hydrolab Dissolved Oxygen sensor is based on a standard Clark Cell design, which is EPA approved, and has been trusted for over 30 years.
- Design based on a standard Clark Cell design, and paired with a sample circulator Measures the current resulting from the electrochemical reduction of oxygen diffusing through a selective membrane Provides a continuous, steady-state reading
- Low maintenance – no need to “recondition” the sensor Complies with Standard Methods Article 4500-OG and EPA article 360.1 that require sufficient sample flow across the membrane Circulator also improves response time for all sensors and helps to sweep away traces of pH electrolyte
