Product Description

Online Fluorescence Dissolved Oxygen Tester probe modbus protocol fluorescent material

Description

Blue light from a light-emitting diode (LED) illuminates the fluorescent material on the inner surface of the fluorescent cap, and the fluorescent material on the inner surface is excited to emit red light by detecting the phase difference between red and blue light and the internal calibration value.
