## Description
Summary: Summary
CTX Total Chlorine, Bromine, and pH Analyzer Kit (Code: 25948) is a professional liquid reagent-based testing solution, ideal for quick and reliable water analysis in residential pools and spas. Combined with OTO and Phenol reagents, it ensures precise monitoring of water sanitization levels and pH balance.
Benefits

Simple and fast results—monitor your pool water quality in minutes.
Accurate measurement of chlorine, bromine, and pH levels.
Affordable daily use for homeowners and maintenance professionals.
Helps avoid incorrect chemical balances that may damage pool surfaces or irritate skin and eyes.
Portable and easy-to-store case format.

Detailed Information: 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.
The 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.
Detailed Features

Liquid OTO Reagent: Reacts with chlorine or bromine, turning yellow for oxidation detection.
Liquid Phenol Red Reagent: Changes from yellow to red-violet, depending on pH variation.
Precise Dosage: Drop-by-drop measurement allows for fine control of test sensitivity.
Multiple Sizes Available: 15 cc and 250 cc bottles for personal or professional use.
Kit Format: Includes measuring tubes and color scale for easy interpretation.

Comprehensive Description
Ortho-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.
Phenol 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.
Using this analyzer kit ensures that your pool remains safe, hygienic, and enjoyable for swimmers while also protecting pool infrastructure from chemical imbalances.
Usage Tips

Always perform the OTO test before the pH test—high chlorine levels can affect the accuracy of the pH reading.
Rinse cuvettes thoroughly with the same pool water to avoid contamination and inaccurate results.
Store reagents in a cool, dry place away from sunlight.

Safety Information

Use protective gloves and glasses when handling reagents.
Keep all components out of reach of children.
Do not ingest or inhale reagents—use in well-ventilated areas.
Dispose of used water samples and reagents responsibly, according to local waste guidelines.

Do’s and Don’ts

Do test your water daily, especially in peak usage periods.
Do replace reagents as they expire or lose effectiveness.
Don’t mix OTO and Phenol tests together.
Don’t perform the pH test before checking chlorine levels.
