Principle
The instrument uses a 515nm wavelength LED Illuminant to illuminate the sample and quantitatively analyze the residual chlorine and total chlorine concentrations by measuring the change in the sample's Absorbance to specific wavelengths of light. The instrument has built-in calibrated Linear dispersion, supports 1 point calibrated to ensure measurement accuracy, and uses a 25mm Colorimetric bottle as a measurement cell for detection.
Applications
Water quality testing, environment monitoring, drinking water safety, swimming pool water quality control, industrial water treatment
Standards
The product information does not mention specific compliance standards
