Lock-In Based Phase Fluorometric Dissolved Oxygen Sensor Interface With 4 kHz – 150 kHz Tunable Excitation Frequency and Frequency Error Calibration

Optical dissolved oxygen (DO) concentration measurement based on phase fluorometric theory is one of the most promising DO concentration measurement methods with advantages of insensitivity to the solution, short response time, and satisfying maintainability. However, most phase fluorometric DO conc...
