Water Dissolved Oxygen Analyzer with RS485 Output for Sewage

Water Dissolved Oxygen Analyzer with RS485 Output for Sewage
The optical dissolved oxygen sensor measures dissolved oxygen using the principle of oxygen dynamic luminescence quenching technique. When blue light excites sensor film, the sensing film emits red light. The phase difference between the blue excitation and returned red emission is measured, and the result is used to calculate DO concentration.
