TR-2000 water quality analyzer

Product Description: Photometer TR-2000 with photoelectric technology & microprocessor technology is widely used to test water pH, free chlorine and total alkalinity in swimming pools, spas, and hot tubs. Working Principle: When the test strip is placed in the water, the reagent on the test pad will react with the water, causing water changing colors. Due to different concentrations of the substance to be tested in the water, the color will also be different. A specific wavelength of light will be absorbed when the incident light in the instrument passes through the sample tube, and the degree of absorption is related to the color of the liquid in the sample tube.
