Hardness Analyzer
Model CA-600
The Hardness Analyzer is an on-line sequential sampling analyzer, a sequence of sampling, analysis and result processing is performed and repeated using colorimetric methods. The measurement is a colorimetric analysis using an LED light source and a heated colorimetric cell designed for measuring trace amounts of analyse in water.
The colorimetric analyzer is assembled with two separated sections. The bottom section is the LIQUIDS section. It includes all of the components involved in the flow, mixing and reaction stages of the sample and reagents. Numerous analysis configurations can be programmed, depending on accessories and of the number of micro pumps mounted in the Liquid Section. The top section is the ELECTONICS enclosure. It includes the main power supply, the controller PCB assembly and the touch screen interface.
The measuring Principle
The photometric determination is based on the reaction of calcium with O-cresolphalein Complexone solution, which yields a violet colored complex. The intensity of the color formed is proportional to the calcium concentration in the sample. Absorbance of the complex is measured at 572 nm.
