• 【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..

RCYAGO Dissolved Oxygen Meter with Electrode Filling Fluid

• Dissolved oxygen meter is a precision instrument for measuring dissolved oxygen and temperature. The dissolved oxygen probe is a thin film with a polarographic sensor and a thermistor for temperature measurement and temperature compensation. The permeable membrane separates the measured solution from the sensing electrode but allows oxygen to pass through the membrane to react, and the concentration can be measured..
• Dissolved oxygen refers to the concentration of molecular oxygen dissolved in water, generally expressed in mg/L (ppm) and saturation percentage (%), which is the percentage of dissolved oxygen in 1L of water. The oxygen concentration of our dissolved oxygen meter is 0.0-40.0mg/L, most of the range of dissolved oxygen meters on the market is 0.0-20mg/L. When measuring and calibrating, needn't open the protective cover of the electrode, just put the electrode in the solution for measurement..
