Product Description

Yosomitech Y504-A Dissolved Oxygen Sensor is an online device for measuring dissolved oxygen in water. Our Optical Dissolved Oxygen Probe adopts oxygen dynamic luminescence quenching technique; when blue light excites sensor film it emits red light which can then be measured to calculate DO concentration. When blue excitation meets red emission the phase difference between them can be calculated and then used to calculate DO concentration.

Y504-A Do Sensor doesn't consume oxygen, has no flow rate limit, doesn't require electrolyte, is free of frequent maintenance and calibration, isn't affected by hydrogen sulfide, and has excellent accuracy and stability. It's widely used in waste water treatment, water quality monitoring, drinking water treatment, etc..
