5-in-1 Pool and Spa Tester: pH, salinity, temperature, ORP and TDS – precise, waterproof, with backlit LCD display

Pool salinity test – salinity range: 0–9990 ppm/10–100 ppm; Monitors the salt concentration in saltwater pools and hot tubs with salt electrolysis systems; Helps salt electrolysis systems operate more efficiently with the correct salinity. pH test for your pool – pH range: 0.00–14.00; depending on the pool type (fiberglass, vinyl, and tile), a pH of 7.2–7.8 is recommended. Optimal performance and cleaner water are achieved when the pH is within the normal range. Test strips vs. digital meters – When using test strips, the cell value must be estimated based on the strip's color; however, a digital meter provides an accurate reading, eliminating the guesswork. Additionally, using too many test strips can become more expensive in the long run. Multifunctional salinity meter: The ORAPXI 5-in-1 meter measures salinity, pH, TDS, EC, and temperature, making it suitable for most saltwater hot tubs and spas. Easy to use: Simply immerse the meter in the pool water, and the LCD display will show the results within seconds.
