Digital Pool Test Kit Meter 6 in 1 - SALT ORP pH TDS Test Parameters: pH (0.01- 14.00 pH); Chlorine (ORP / REDOX) -999mV ~ +999mV Salinity SALT (0.00-25.0%; 0-9990ppm; 10.1-200.0ppt) Electrical Conductivity EC (0-9990 uS/cm 10.01-19.99mS/cm 20.1-400mS/cm) Total Disolved Solids TDS (0-999ppm; 1000-9990ppm; 10.1-200.0 ppt) Temperature (0.1-60.0℃ 32.0-140℉) Pool Chemical ranges should be kept within the following(tester does not test for all of these): Chlorine - summer at 3ppm, winter 1.5ppm for a standard salt pool. PH between 7.2 - 7.6 Alkalinity between 80 - 120ppm Stabiliser between 30 - 50ppm Calcium hardness between 180 - 250ppm Salt generally 3500ppm however your specific chlorinator may suggest 4500ppm - 1500ppm.
