PCH-800 Chlorophyll Online Analyzer


Predict algae blooms and determine the nutrient loading in water with the PROBEST CH-800A  Chlorophyll Sensor.


Overview

The PROBEST CH-800A Chlorophyll Probe expands PROBEST suite of sensors for multi-parameter MUC200, water quality monitoring applications. The probe is designed to estimate phytoplankton concentrations by detecting the fluorescence from chlorophyll in situ. The data can be useful in predicting detrimental algae blooms and, indirectly, in determining nutrient loading in environmental applications. The probe is capable of long-term water quality onsite monitoring.


The PROBEST  CH-800A Chlorophyll Probe uses technology similar to that used by fluorometers, but the PROBEST sensor is much smaller, making it compatible with the probe ports in PROBEST 7-Series instruments, MUC200 which max is 7sensors, with simultaneous measurement of 7 optical probes (dissolved oxygen, turbidity, chlorophyll, blue-green algae, and/or rhodamine, COD, Ammonia, Conductivity, ph), along with other parameters.


Features include:

Fast, convenient, in-situ monitoring

For online long-term measurement

Small field-replaceable probe design


Chlorophyll is in various forms is bound within the living cells of algae, phytoplankton, and other plant matter found in water. Chlorophyll is a key component in the process of photosynthesis, the critical process in which energy from sunlight is used to produce life-sustaining oxygen. The amount of chlorophyll in a water sample is used as a measure of suspended phytoplankton, the magnitude of which can significantly affect the overall quality of water. Before this PROBEST sensor made in situ measurement convenient, the common way to measure chlorophyll was to collect samples and use extractive analysis in a laboratory or take large equipment to the field. Extractive analysis methods, though highly accurate, are time-consuming and require an experienced analyst. The PROBEST optical, fluorescence probe is quick and efficient to use and enables spot sampling in remote areas as well as continuous or interval monitoring.



n  Measurement Principle

The principle of PCH-800 Chlorophyll Sensor is using the characteristics of chlorophyll A who has absorption peaks and emission peaks in the spectrum.
