Color sensor series adopts visible‑light spectral‑absorption principle to quantify true dissolved chroma calibrated against Pt‑Co Hazen scale, distinguishing dissolved‑substance‑triggered water discoloration from particle‑caused turbidity interference. Unlike laboratory color‑comparison cuvette testing, this reagent‑free dual‑beam optical setup delivers continuous in‑situ readings, removing manual sample preparation and subjective visual judgement errors.
Embedded dual‑beam algorithm implements real‑time turbidity‑cancellation to offset signal distortion caused by suspended particles, securing credible true‑color outputs for both clear source‑water and particle‑laden industrial effluents. Optimised optical path design suppresses bubble‑induced signal fluctuation during pipeline flow conditions. Shifts in chroma serve as indirect indicators for abnormal industrial discharge, incomplete decolorisation treatment or intrusion of humic organics within raw water intake.
Deployed for drinking‑water purification lines, textile‑plant effluent outlets, surface‑water catchment monitoring and water‑treatment process validation, these probes feed persistent chroma datasets into customised water‑monitoring solutions. Operators utilise long‑term colour‑trend archives to audit decolorisation efficiency and satisfy regulatory requirements for effluent visual‑quality constraints.
