Sensafe Exact Micro 7 Calcium Test Strips

These Calcium Hardness Test Strips 486629 are used in the Sensafe Exact Micro 7 Photometer and in other water testing micro meters.

Spa and Swimming pool owners should test pool water for calcium regularly to ensure their hardness is in the proper range. Low calcium levels can result in corrosive water, which stains pool surfaces and destroys tile grouting and metal or plastic equipment. Likewise, if your pool water calcium level is too high and your water is too hard, scale can form on pool surfaces and in your pipes. High calcium hardness in pools can also lead to sore eyes.

• Contains 50 calcium pool test strips
• Detection Range: 20 - 990 ppm
