Chlorophyll Sensor

Product Description

Description

SC9260-CP Chlorophyll sensor uses fluorescence to measure phycocyanin inside chlorophyll and its derived substances in water. The content of chlorophyll is calculated by the released fluorescence energy when excited by a high-energy LED light source. SC9260-CP sensor emits a LED light beam of 470nm through water; It excites chlorophyll in water to produce fluorescence with a specific wavelength which is then employed to measure the concentration of chlorophyll. SC9260-CP sensor is particularly suitable for scientific research as well as for online water quality monitoring of ground water, surface water and other water applications.

Application

Lake, reservoir, underground and river water
Hydrocarbons are dangerous pollutants that have to be detected very early on reservoir or river for producing drinking water. Fast and reliable measuring system is necessary, and the UV fluorescence is the only method matching these requirements.

Cooling water survey
The concentration of hydrocarbons in cooling water is a critical parameter on refineries.

Wastewater monitoring
The effluents of refineries and chemical plants have to stay below limits to meet the environmental regulations. A reliable and low maintenance measuring system is required and only UV fluorescence approach achieves this goal.
