Keeping free chlorine in the typical range of 1-3 ppm helps purify the water while preserving clarity, making the pool look inviting and ensuring swimmers enjoy a healthy, comfortable swim. - Salt Tester for Saltwater Pool - Salinity meter checks salt level (2700-3400 ppm) for saltwater pools and hot tubs with a salt chlorinator system. Maintains efficient chlorinator operation at the proper salinity and helps keep the pool clean while preventing issues from too much or too little salt on people and equipment. - pH Level Tester for Pool - Measures pH from 0.00 to 14.00. Maintaining proper pH is critical for saltwater pools, with a typical target of 7.2–7.8. Regular testing and adjustment support clean water, comfortable swimming, and protect pool equipment from damage. - Pool Chlorine Tester vs Pool Test Strips - Free chlorine meters are simpler, more accurate, and friendlier to color-insensitive users than test strips. To read, simply place the tester in the water for a few seconds for an accurate result. Use scenarios - Home pool maintenance: perform regular checks of chlorine and pH to sustain clean, balanced water. - Saltwater pools and hot tubs: monitor salinity to optimize the salt chlorinator and protect users and gear from imbalance. - Post-chemical adjustments: verify chlorine and pH after adding chlorine, pH up/down products, or salt, ensuring quick, reliable readings.
