YCKYIGO Salt Water Pool Tester Large Range 7 in 1 Multi-Parameter Tester for Salt Swimming Pool and Spa

... 【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 clean, clear pool water. Pools with high TDS tend to have chronic issues with cloudy water. Keep in mind that saltwater pools will have a higher TDS level because of the higher salt content. The rule of thumb is that TDS levels should not be higher than 1500 ppm ab....
