Digital signal dissolved oxygen sensor

Fluorescence method Dissolved oxygen sensor is based on the physics of specific substances on the activity of fluorescence quenching principle. The blue light from a light-emitting diode (LED) illuminates the fluorescent substance on the inner surface of the fluorescent cap. The fluorescent substance on the inner surface is excited to emit red light. By detecting the phase difference between the red and blue light, To calculate the concentration of oxygen molecules, through the temperature and pressure automatically compensate for the final output value.
