Working Principle
The GW-2000E uses different analytical methods according to the selected measurement parameter.
Optical Colorimetric Analysis
For colorimetric parameters, the water sample reacts with specific reagents to produce a colored compound. The analyzer automatically selects the required wavelength and measures the absorbance or transmittance of the sample.
The measured optical signal is compared with the corresponding standard curve, and the instrument calculates the concentration of the target substance. This method can be used for parameters such as:
•  COD
•  Ammonia nitrogen
•  Total phosphorus
•  Total nitrogen
•  Copper
•  Iron
•  Nickel
•  Hexavalent chromium
•  Phosphate
•  Nitrite
•  Residual chlorine
•  Other customized colorimetric parameters
Electrochemical Measurement
For pH, conductivity and dissolved oxygen, the GW-2000E uses dedicated electrochemical electrodes. The electrode detects the relevant electrical or electrochemical signal in the sample, and the analyzer converts the signal into the corresponding water quality value.
Turbidity Measurement
Turbidity can be measured using the light-scattering method or scattering-plus-transmission method, depending on the selected configuration.
