The Industry Standard for Clear, Accurate pH Testing

The Taylor R-0004 Phenol Red pH Indicator Reagent is the core solution used for testing pH levels in pool and spa water with Taylor's liquid test kits. This 2-ounce high-volume refill bottle provides the essential colorimetric reaction that allows you to instantly visualize your water's acidity or basicity. Accurate pH testing is the cornerstone of water balance, and this trusted reagent delivers the reliable, easy-to-read results necessary for protecting your equipment and ensuring swimmer comfort.

Key Features & Benefits:

• Instant, Visual pH Reading: This reagent contains Phenol Red, an indicator dye that reacts to the hydrogen ion concentration in water, producing a color spectrum from yellow (acidic, low pH) to orange/red (ideal range) to purple/red (basic, high pH). This allows for quick and intuitive interpretation against the provided comparator.

• Protects Your Pool Investment & Swimmers: Maintaining proper pH (7.4-7.6) is critical. This reagent helps you prevent low pH (corrosive water that damages heaters, pumps, and surfaces) and high pH (which causes scaling, cloudy water, and reduces chlorine effectiveness). It also ensures a comfortable swimming experience free from eye and skin irritation.

• Professional-Grade Reliability & Value: The 2-ounce (R-0004) size offers a larger, more economical supply for frequent testers and professionals, reducing the frequency of refills. It is manufactured to exacting standards for consistent performance in every drop.

• Universal Compatibility: This is the standard pH indicator used across a wide range of Taylor test kits, including the popular 2000 Series (K-2005, K-2006), making it a versatile and essential refill to keep on hand.

• Maintains Test Kit Accuracy: This is a direct refill for the R-0004 reagent supplied in your kit. Replacing consumed or expired reagents is crucial for maintaining the integrity of your test results. Taylor recommends replacing this reagent annually for optimal performance.

How It Is Used:

1. Fill the pH test vial with the required amount of pool water (typically 44 mL or to the marked line).

2. Add 5 drops of R-0004 Phenol Red Reagent to the vial and swirl to mix.

3. Immediately place the vial in the comparator holder and compare the color of the sample against the printed pH standards.

4. Match the color to determine your water's pH level.

Important Note: This product is a chemical reagent refill for use with specific Taylor liquid test kits and is not a standalone product. For the most accurate reading, ensure the test vial is clean and view the colors in natural daylight if possible.

• Pool and Spa Service Professionals

• Owners of Taylor test kits that use Phenol Red for pH testing (e.g., K-2005, K-2006)
