Taylor R-0011L-A Calcium Indicator Liquid | 0.75 oz.

The Taylor R-0011L-A Calcium Indicator Liquid (0.75 oz) is a precision reagent formulated for use in Taylor pool and spa test kits to measure calcium hardness levels accurately. This indicator works in tandem with Taylor reagents R-0010 and R-0012, providing the key color-change stage in the titration process that signals endpoint completion. Built to Taylor’s OEM specifications, the R-0011L-A ensures consistent and reliable test results, maintaining proper water balance and preventing scaling or corrosion issues. Regular use helps pool operators verify hardness control for clearer, safer, and more stable water conditions.

Highlights

• Calcium Hardness Testing: Enables accurate measurement of calcium levels when used with Taylor R-0010 and R-0012 reagents in standard test kits.

• 0.75 oz Liquid Indicator: Compact dropper bottle provides precise dosing for both residential and commercial testing routines.

• OEM-Standard Formula: Manufactured to Taylor’s original specifications for consistent accuracy and reliable color-change performance.

• Supports Equipment Longevity: Proper hardness monitoring prevents corrosion, scaling, and deterioration of heaters, pumps, and pool surfaces.

• Annual Replacement Tip: Replace Taylor reagents every year to maintain test precision and ensure consistent water chemistry results.
