Product Description
Technology principle
The light from LED Lamp source penetrates the sample cell, and is caught by the detector. After magnetization, disposal, modulus change, calculation and analyses, display the final result controlled by the MPU.
The sample gets chemical colorific reactions with some special reagent, and then the mixture can absorb visible light at some wavelength obviously. The absorption intensity have direct ratio with the concentration of the sample. We detect the signal change between the two results before and after the sample cell, and then get the sample concentration by calculation.
