7-in-1 pool salinity tester: pH/free chlorine/ORP/EC/TDS/salt/temperature, IP67 waterproof

7-in-1 Electronic Pool Tester - Accurate and Complete Analysis

Take perfect control of your pool or spa water quality with this multifunctional electronic tester. Fast, accurate, and easy to read, it's a superior replacement for test strips, giving you all the essential measurements for crystal-clear, healthy, and balanced water. 7 Parameters in One Step: This tester combines seven fundamental measurements in a single compact device: pH (0.00 to 14.00): Crucial for bather comfort and disinfectant effectiveness. Free Chlorine (FC): Direct measurement of active chlorine disinfectant. Salinity (Salt): Essential for salt-treated pools (ideal range: 2700-3400 ppm). Temperature: Displayed in °C or °F. TDS (Total Dissolved Solids): Indicator of water mineralization. EC (Conductivity): Related to salinity and... TDS.

ORP (Redox Potential): Measures the overall disinfecting power of the water.

Accuracy and Ease of Use

Simply immerse the electrodes in the water, wait a few seconds for stabilization, and read the results on the clear digital LCD screen, often backlit for evening reading. This method is much more accurate and objective than the subjective interpretation of colors on test strips. A HOLD function allows you to freeze the display to note the values.

Optimal Operating Conditions

For reliable chlorine readings, the water's pH should be between 6.5 and 8. The device operates on 4 LR44 button cell batteries (not included). This is the essential tool for pool owners (traditional or salt) and spa owners concerned with scientific and effective maintenance, allowing them to precisely adjust chemical products and achieve long-term savings.
