Taylor R-0012-E Hardness Reagent - 16 oz

Precise Calcium Hardness Testing for Balanced Pool and Spa Water

Taylor R-0012-E Hardness Reagent is a 16 oz bottle used to determine calcium hardness in pool and spa water as part of Taylor's testing kits. It participates in the colorimetric hardness test by reacting with a water sample to produce a color change that corresponds to calcium hardness levels. Use this reagent in conjunction with the R-0012-E hardness testing workflow to obtain precise calcium hardness readings and guide balancing steps for healthy water and protected equipment.

Construction, Compatibility and Integration

The reagent is manufactured by Taylor Technologies for compatibility within their calcium hardness testing system. It is provided in a 16 oz bottle and is intended to be used with Taylor's standard hardness testing procedure, including the R-0012-E steps. The formulation supports reliable color development with pool and spa water samples, enabling consistent readings when paired with the Taylor color comparator or reference chart. Store per label directions and keep the bottle tightly closed when not in use.
