Taylor R-0012-A-24 Calcium Hardness Reagent #2 – 24 oz Refill
The Taylor R-0012-A-24 is a 24 oz refill bottle of Calcium Hardness Reagent #2 used in Taylor’s drop-count titration for measuring calcium hardness (CH) in pool and spa water. This reagent is added after the hardness buffer and the indicator, then titrated until the sample changes color to determine the calcium hardness level.
Key Features
- For calcium hardness (CH) testing using the Taylor titration method
- 24 oz refill size for frequent testing or service use
- Used in many Taylor kits that include calcium hardness testing
- Helps prevent common water balance issues like scale formation (high CH) and etching/corrosion (low CH)
How It’s Used (Overview)
- Add Taylor hardness buffer and hardness indicator to your measured water sample (per kit instructions).
- Drop-count titrate with R-0012 until the color changes to the test endpoint.
- Calculate CH based on the number of drops and the sample size used.
