Pyxis SP-210 Bleach Concentration Meter

The Pyxis SP-210 Handheld Bleach Analyzer is a highly portable, real-time analyzer engineered to measure sodium hypochlorite concentrations accurately and effortlessly. Designed for both concentrated commercial bleach and diluted electrolysis-generated solutions, the SP-210 provides direct %Cl₂ (mass/mass) readings with no sample shielding or vials required — just pour the bleach directly into the integrated sample cell.

Using an advanced UV LED optical system and algorithmic compensation for ambient light, the SP-210 eliminates the limitations of traditional titration methods. Its built-in RTD sensor provides temperature readings and automatic compensation for a wide range of sample temperatures, ensuring precise, repeatable results in industrial, municipal, and water treatment applications. Measure bleach concentrations up to 16% with confidence — fast, accurate, and field-ready.
