  • 【Wonderful Helper for Pool Salinity Measurement】This salinity meter is perfect for testing the salinity of swimming pools. It helps you to detect the salt level in your salt system. Scale range: 0~9999 ppm/10.0~200 ppt and 0.00-25.00%..
  • 【Detects Free Chlorine Levels】The ORP value is a measure of the oxidative power or sterilization strength in water pool salt. The higher the ORP value in water, the stronger the oxidative power and sterilization ability. The ORP's can reflect the residual chlorine (FAC) levels in the Saltwater pool..
  • 【Highly Sensitive PH Probe】A low pH means the water is acidic, which can be corrosive to pool equipment and pool surfaces. It may also cause skin and eye irritation. A high PH value can greatly reduce the effectiveness of chlorine and cause the water to become cloudy. To avoid problems, it’s important to try and keep it within the ideal range of 7.4–7.6. This PH test pen will do the job perfectly..
  • 【Platinum Electrodes for TDS】Total Dissolved Solids (TDS) is a measurement of all dissolved solids in pool water. The higher the TDS reading, the harder it is to maintain clea....
