Relay Automatic Dosing Chlorophyll Transmitter For Reservoir


The chlorophyll sensor utilizes the characteristic that chlorophyll has absorption peaks and emission peaks in the spectrum. At the spectral absorption peak of chlorophyll, it emits monochromatic light and irradiates it into the water.

The chlorophyll in the water absorbs the energy of the monochromatic light and releases another wavelength. The monochromatic light of the emission peak, the light intensity emitted by chlorophyll is proportional to the content of chlorophyll in the water.

Configure the DUC2-CHL controller to humanize the data measured by the sensor. Realize the functions of relay control and digital communication.
