Combined with OTO and Phenol reagents, it ensures precise monitoring of water sanitization levels and pH balance.\nBenefits\n\nSimple and fast results—monitor your pool water quality in minutes.\nAccurate measurement of chlorine, bromine, and pH levels.\nAffordable daily use for homeowners and maintenance professionals.\nHelps avoid incorrect chemical balances that may damage pool surfaces or irritate skin and eyes.\nPortable and easy-to-store case format.", "description": "This CTX analyzer kit is your go-to tool for keeping your pool or spa clean, balanced, and safe. Designed for everyday use, it includes liquid reagent bottles that react with water samples to provide visual cues—yellow for oxidizers using Ortho-Toluidine (OTO) and color-shifting indicators for Phenol Red to determine pH levels.\nThe color intensity corresponds to chemical concentration, allowing easy estimation through comparison with a provided scale. A crucial part of your pool care routine, this kit offers clarity and peace of mind with every test.\nDetailed Features\n\nLiquid OTO Reagent: Reacts with chlorine or bromine, turning yellow for oxidation detection.\nLiquid Phenol Red Reagent: Changes from yellow to red-violet, depending on pH variation.\nPrecise Dosage: Drop-by-drop measurement allows for fine control of test sensitivity.\nMultiple Sizes Available: 15 cc and 250 cc bottles for personal or professional use.\nKit Format: Includes measuring tubes and color scale for easy interpretation.\n\nComprehensive Description\nOrtho-Toluidine (OTO) is a transparent reagent that turns yellow in the presence of oxidants like chlorine and bromine. The darker the yellow, the higher the concentration—making it a reliable tool for maintaining disinfectant levels.\nPhenol Red, on the other hand, is a pH-sensitive dye that shifts color from yellow to red-violet depending on the acidity or alkalinity of the water. This allows you to keep your pool within the recommended pH range for comfort, safety, and chemical efficiency.\nUsing this analyzer kit ensures that your pool remains safe, hygienic, and enjoyable for swimmers while also protecting pool infrastructure from chemical imbalances.\nUsage Tips\n\nAlways perform the OTO test before the pH test—high chlorine levels can affect the accuracy of the pH reading.\nRinse cuvettes thoroughly with the same pool water to avoid contamination and inaccurate results.\nStore reagents in a cool, dry place away from sunlight.\n\nSafety Information\n\nUse protective gloves and glasses when handling reagents.\nKeep all components out of reach of children.\nDo not ingest or inhale reagents—use in well-ventilated areas.\nDispose of used water samples and reagents responsibly, according to local waste guidelines.\n\nDo’s and Don’ts\n\nDo test your water daily, especially in peak usage periods.\nDo replace reagents as they expire or lose effectiveness.\nDon’t mix OTO and Phenol tests together.\nDon’t perform the pH test before checking chlorine levels.\n\nAvailable Variants\n\nAstuccio analizzatore CTX di cloro totale, bromo e pH a reagenti liquidi – Code: 25948\nReattivo OTO 15 cc – Code: 28016\nReattivo Phenol 15 cc – Code: 28017\nReattivi OTO + Phenol 15+15 cc – Code: 16577\nReattivo OTO 250 cc – Code: 03308\nReattivo Phenol RED 250 cc – Code: 03309\n\nLegal Note\nProduct intended for professional and domestic use only.
