Chlorophyll Sensors FAQs

What is a Chlorophyll Sensor in water?

A Chlorophyll Sensor is a instrument which measure Chlorophyll value in water.
Working Principle: Chlorophyll fluorescence is light re-emitted by chlorophyll molecules during return from excited to non-excited states.

Why do we test for Chlorophyll?

Measuring chlorophyll in water is important to estimate the abundance of phytoplankton. If a high level of chlorophyll is detected, it is an indication that a high level of phytoplankton is present in the water. … The natural chlorophyll levels in water fluctuate over time.

What is Chlorophyll Concentration?

Ocean Chlorophyll Concentrations. The concentration of chlorophyll is an indicator for the amount of photosynthetic plankton, or phytoplankton , present in the ocean. Phytoplankton populations are influenced by climatic factors such as sea surface temperatures and winds.

How is Chlorophyll Fluorescence measured?

Chlorophyll fluorescence appears to be a measure of photosynthesis, but this is an over-simplification. Fluorescence can measure the efficiency of PSII photochemistry, which can be used to estimate the rate of linear electron transport by multiplying by the light intensity.

What is the unit of Chlorophyll content?

The patented Apogee model MC-100 chlorophyll concentration meter measures relative chlorophyll content and outputs an estimate of actual chlorophyll concentration in units of µmol per m2 of leaf surface (µmol m-2); mass per area of leaf surface, milligrams per square meter (mg m-2), has also been used.
