Full Spectrum Water Quality Analyzer

The full-spectrum water quality analyzer irradiates the water sample with a continuous-wavelength light source, measures the absorption spectrum of substances in the ultraviolet to visible light bands, and calculates the concentration of pollutants based on the Beer-Lambert law. It is used for real-time monitoring of indicators such as COD and nitrates in water, and is suitable for applications in wastewater treatment, drinking water monitoring, and other fields.
Selection
When selecting, ensure the spectral range covers 200–720 nm and the instrument is capable of multi-parameter simultaneous detection. Pay attention to whether the detection limit meets local emission standards and examine the instrument’s anti-interference performance. Prioritize models with automatic cleaning and temperature compensation functions to ensure long-term operational stability. Verify whether the instrument has national metrology certification.
