LaMotte 3887A-J Calcium Hardness Test Tablets – 100 Foil-Wrapped Tablets for ColorQ 2X

LaMotte 3887A-J Calcium Hardness Test Tablets are a trusted reagent for use with the ColorQ 2X digital water testing system. These tablets enable precise calcium hardness measurements in swimming pools and spas by producing a colorimetric reaction analyzed by the ColorQ photometer.
Each tablet is individually foil-wrapped to protect from moisture and extend shelf life, ensuring consistent performance and ease of use in the field or at home. Maintaining proper calcium hardness is essential to prevent scale formation, corrosion, and water imbalance that could affect comfort, safety, and equipment longevity.
Perfect for pool professionals, aquatic facilities, and homeowners using ColorQ 2X PRO 7 or PRO 9 test kits.
