The Vital Color-Changer for Precise Calcium Hardness Testing

The Taylor R-0011L-C is a critical liquid indicator reagent used in the Calcium Hardness test within Taylor's 2000 Series and other compatible professional test kits. This 2-ounce bottle is a high-volume refill that provides the essential color change needed to accurately determine your water's calcium levels. For pool and spa professionals and serious owners, this reagent is key to preventing costly scale formation and corrosive water conditions.

Key Features & Benefits:

• Enables Visual Measurement: This reagent contains the indicator dye (Eriochrome Black T) that causes the water sample to turn red in the presence of calcium ions. As you add the titrant, the color shifts from red to blue, providing a clear, unambiguous endpoint for the test.

• Prevents Scale and Corrosion: Accurate calcium hardness testing is crucial for protecting your pool. This reagent helps you maintain ideal levels (200-400 ppm for most pools) to prevent scale buildup on surfaces and equipment (if too high) or corrosive water that can etch plaster and damage metal components (if too low).

• Professional-Grade Reliability & Value: The 2-ounce (R-0011L-C) size offers a larger, more economical supply for frequent testers and professionals, ensuring you never run out during the critical pool season. Trusted for its consistency and performance.

• Maintains Test Kit Integrity: This is a direct refill for the R-0011L reagent supplied in your test kit. Replacing consumed or expired reagents is essential for maintaining the accuracy and reliability of your entire water testing system. Taylor recommends replacing this reagent annually for optimal performance.

• Proudly Made in the USA: Manufactured by Taylor Technologies with rigorous quality control standards, ensuring precise performance in every drop.

How It Is Used:

The R-0011L-C is used in a specific sequence within the Calcium Hardness test:

1. A water sample is added to the test vial.

2. 20 drops of R-0010 Calcium Hardness Buffer are added and swirled.

3. 5 drops of R-0011L-C Calcium Hardness Indicator are added and swirled, turning the sample red.

4. The sample is then titrated with R-0012 Calcium Hardness Titrant drop by drop until the color changes from red to blue. The number of drops used calculates the Calcium Hardness in ppm.

Important Note: This product is a component refill and cannot be used as a standalone test. It must be used as part of a complete Taylor liquid test kit (such as the K-2005 or K-2006) that includes a Calcium Hardness test.

Ideal For:

• Pool and spa service professionals

• Owners of Taylor 2000 Series test kits (K-2005, K-2006) or other compatible kits

• Commercial pool operators

• Any pool owner concerned with water balance and protecting their investment from scale or corrosion

What's in the Box:
