Description
Restore precision to your water analysis with the official Taylor R-0009 replacement reagent. Containing 22 mL (0.75 oz) of 0.12N Sulfuric Acid, this vial is the necessary acid component required for proper titration in standard Taylor testing systems. It enables accurate measurement of total alkalinity and calcium hardness, critical metrics for maintaining safe and balanced pool water chemistry.
Precision Calibration
Using third-party acids can introduce variance in color change endpoints and volume calculations. Factory-referenced solutions like R-0009 match your titration burette calibrations exactly, eliminating variables that lead to misleading pH or chlorine level readings. The A size designation indicates the standard volume capacity intended for repeated testing sessions before replenishment.
Annual Replacement Protocol
Even stored in optimal conditions, liquid reagents lose stability over time. For the most reliable troubleshooting results, recommend reagent replacement schedules coincide with an annual service interval. Fresh supply ensures you get the most accurate results possible and keeps your water chemistry properly balanced for years.
Safety Precautions
Handle with care as sulfuric acid is corrosive. The container features distinct safety markings, including a mandate to keep the product out of reach of children. Follow all disposal guidelines appropriate for industrial chemical waste to ensure compliance with local environmental regulations.
