Leveraging an advanced optical system, this instrument delivers accurate and consistent readings by effectively minimizing interference from stray light and color in the sample. Built-in calibration using supplied standards compensates for any fluctuations in the tungsten light source. For chlorine analysis, the colorimeter employs a narrow 525 nm band interference filter, ensuring optimal wavelength for both free and total chlorine detection. All measurements are conducted in 25 mm round cuvettes made of specialized optical glass, which maximizes the repeatability of both turbidity and chlorine measurements.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003ch4 style=\"font-weight: 400; margin-bottom: 8px;\"\u003eKey Features at a Glance:\u003c\/h4\u003e\n\u003cul style=\"font-size: 1rem; line-height: 1.5; list-style-type: disc; margin-left: 20px;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriple Measurement Modes:\u003c\/strong\u003e Offers ratio mode for turbidity, free chlorine, and total chlorine.

Beyond aesthetics, controlling turbidity is a vital safeguard against waterborne pathogens.
