The Final Measure for Precision: Complete Your Calcium Hardness Test with Accuracy

The Taylor R-0012-C Calcium Hardness Titrant is the essential finishing reagent used in the professional titration test for measuring calcium hardness in pool and spa water. This 2-ounce bottle is a high-volume refill designed for pool service professionals and dedicated pool owners who require exact results. By providing a clear, drop-counted endpoint to the test, this reagent allows you to calculate your water's calcium level with laboratory-grade precision, ensuring you can effectively prevent scale and corrosion.

Key Features & Benefits:

  • Precise Drop-Count Titration: This reagent is the titrant used in the final step of the test. You add it to a prepared water sample one drop at a time until the sample undergoes a definitive color change from red to blue. The number of drops used directly calculates the exact Calcium Hardness in parts per million (ppm).

  • Prevent Costly Scale and Corrosion: Accurate calcium hardness testing is fundamental to protecting your pool investment. Using R-0012-C to get a precise reading allows you to maintain ideal levels, preventing scale buildup on heaters and surfaces (if too high) or corrosive water that can etch plaster and damage equipment (if too low).

  • Professional-Grade Reliability & Value: The 2-ounce (R-0012-C) size offers a larger, more economical supply for frequent testing, providing excellent value for professionals and serious enthusiasts. Its standardized concentration guarantees consistent, trustworthy results.

  • Clear, Unambiguous Endpoint: The reaction facilitated by this reagent creates a sharp color change, eliminating the guesswork associated with interpreting subtle color shades. This ensures highly reproducible and accurate readings every time.

  • Maintains Test Kit Integrity: This is a direct refill for the R-0012 reagent supplied in your Taylor test kit. Replacing consumed or expired reagents is critical for maintaining the accuracy of your entire water testing system. Taylor recommends replacing this reagent annually.

How It Is Used:

The R-0012-C is used as the final component in a specific test sequence:

  1. Add water sample to the test vial.

  2. Add 20 drops of R-0010 Calcium Hardness Buffer and swirl.

  3. Add 5 drops of R-0011 Calcium Hardness Indicator and swirl; the sample will turn red.

  4. Slowly add R-0012-C Calcium Hardness Titrant drop by drop, swirling after each drop, until the sample changes from red to a clear blue endpoint.

  5. The number of drops used equals the Calcium Hardness in ppm.

Important Note: This product is a chemical reagent refill for use with specific Taylor liquid test kits (e.g., K-2005, K-2006) and is not a standalone product. It must be used with the other components (R-0010, R-0011) of the Calcium Hardness test.

Ideal For:

  • Pool and Spa Service Professionals

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

  • Commercial pool operators

  • Serious pool owners committed to precise water balance

What's in the Box:

  • One (1) 2-ounce bottle of Taylor R-0012-C Calcium Hardness Titrant.

Complete the Test with Confidence. Ensure Pinpoint Accuracy for Your Water's Hardness with Taylor R-0012-C.
