Product Description

Digital Chlorophyll Sensor

The chlorophyll detection sensor is a blue light source using 470 nm visible

spectrum; This light source can excite chlorophyll a in algae cells in the water to

produce fluorescence, measure the fluorescence intensity in the range of

660-700nm, and calculate the chlorophyll a concentration in the water.

Features

Adopt optical principle, small size, convenient operation, fast detection speed

Excellent repeatability and stability, less susceptible to ambient light

With automatic cleaning brush can make maintenance intervals longer

No reagent consumption required, good stability, low maintenance effort

Internal storage of calibration data, support offline calibration, field plug and play

Standard Modbus communication protocol, support access to standard industrial

control system
