Y504-A Dissolved Oxygen Sensor
DATE:2021-3-1 11:39:42


Yosemitech 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.
