Taylor Technologies Pint Calcium Hardness Reagent R-0012-E, 16 oz — Accurate Pool & Spa Testing

This reagent is the Taylor R-0012-E pint-size solution used with Taylor hardness test kits and titration procedures to measure calcium hardness levels. Accurate calcium hardness readings help you maintain water balance, protect equipment and surfaces, and optimize sanitizer performance. The 16 oz bottle is sized for regular testing without the bulk of larger industrial containers.

How does this reagent work with my calcium hardness test kit?

The reagent is designed to react with the indicator and sample according to Taylor’s established test method, producing a visible endpoint used to calculate calcium hardness. It pairs with the matching titrant/indicator in your Taylor kit for consistent results.

• Compatible with Taylor hardness titration and comparator methods
• Provides clear visual endpoint for reliable readings
• Used in measured drops or milliliter increments per kit instructions

How much testing can I do with a 16 oz bottle?

A 16-ounce (pint) bottle typically provides many individual tests depending on the volume used per test and the testing method (drop count vs. milliliter titration). Home and light-commercial users will find the size balances longevity and shelf life.

• Yields dozens to hundreds of tests based on protocol
• Smaller than gallon bottles, easier to store and handle
• Ideal for routine weekly or biweekly monitoring

What storage and handling practices prolong reagent life?

Keep the bottle tightly capped, stored upright, and away from direct sunlight and temperature extremes to preserve chemical stability. Follow expiration and safety guidance on the Taylor label to maintain performance and safe handling.

• Store in a cool, dry place away from heat and sunlight
• Keep container sealed to prevent contamination or evaporation
• Observe manufacturer shelf-life and dispose per local regulations

Will this reagent fit my existing Taylor test kit?

Reagent #12 is formulated for Taylor calcium hardness procedures and is compatible with most Taylor hardness testing kits that reference R-0012-E or Reagent #12. Confirm your kit’s reagent list to ensure correct pairing and instructions.

• Designed for Taylor R-0012-E referenced kits and protocols
• Check your kit manual for reagent numbering and compatibility
• Using the correct reagent improves measurement accuracy

Who is this for: Pool and spa owners, maintenance professionals, and facilities managers who perform regular calcium hardness testing and prefer a pint-size reagent for ease of handling and adequate test capacity. It’s suited to residential pools, small commercial sites, and anyone using Taylor Technologies’ hardness test procedures who wants the convenience of a 16 oz bottle without buying larger industrial volumes.
