Description
Taylor R-0012 Hardness Reagent is engineered to refill your Taylor water testing kits—specifically for measuring calcium hardness levels in pools and spas. Precision analysis relies on fresh chemicals to distinguish between harmless mineral buildup and problematic scaling or water damage. This single-unit 22 mL (.75 oz) vial ensures your color comparison matches reflect the true condition of your water, allowing you to correct imbalance before it affects plumbing or plaster.
Without reliable reagent levels, your ability to monitor total dissolved solids shifts from fact to guesswork. To maintain the highest standard of accuracy, we recommend replacing this reagent annually. Old solutions degrade over time due to oxidation, potentially leading to faded colors in the test tubes that result in inaccurate dosing of chlorine, shock, or pH adjusters.
The reagent comes packaged in a bottle featuring a tight-sealing blue cap with a pointed tip designed for dispensing precise drops directly into the glass sampling wells. This specialized delivery method minimizes spills and keeps the solution isolated from outside humidity between tests. After use, ensure the cap is securely fastened to preserve the liquid integrity.
