When added to a sample, these color-developing tablets help reveal chlorine species through a distinct color change, enabling easier interpretation by colorimeters and spectrophotometers.\u003c\/p\u003e\n\u003cp\u003eThese tablets are specifically labeled “Instrument Grade,” signaling their suitability for higher-precision instruments. They fit well in controlled testing environments such as laboratories, classrooms, or professional water-testing workflows where accurate color readings matter. In typical testing, a 10 mL sample yields a readable range from 0 to 10 ppm of free chlorine, providing a practical window for routine checks without guesswork.\u003c\/p\u003e\n\n\u003ch3\u003eWhat you get and why it matters\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e100 tablets per bottle for ongoing testing without frequent replacements\u003c\/li\u003e\n  \u003cli\u003eDPD indicator chemistry (diethyl-p-phenylenediamine) that differentiates chlorine forms in the sample\u003c\/li\u003e\n  \u003cli\u003eLong shelf life of roughly three years when stored properly\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cul\u003e\n  \u003cli\u003eDesigned for ColorQ colorimeters and other instrument-grade readers for consistent results\u003c\/li\u003e\n  \u003cli\u003eUseful for measuring free chlorine levels in water samples, with a clear readout on compatible devices\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePractical usage tips\u003c\/h3\u003e\n\u003cp\u003eFor best results, follow your ColorQ kit protocol.
