7 in1 Pool Water Tester, Thermometer, pH & Salt Meter, Digital Pool TDS EC ORP SG Salinity Test Kit, High Accuracy Water Quality Monitor for Swimming Pool, Spa, Hot Tub, Hydroponics & Aquarium

Introducing our advanced Pool Salt Tester & pH Meter - the ultimate all-in-one water quality monitoring device designed for precision and convenience. This professional-grade digital meter combines seven essential testing functions into one compact, easy-to-use instrument, making it the perfect choice for pool owners, spa operators, aquarium enthusiasts, and hydroponic growers who demand accurate and comprehensive water analysis. Our innovative meter simultaneously measures seven critical water quality parameters: pH Level (0.0-14.0 pH): Ensures proper acidity/alkalinity balance Salinity (0-10.0%): Monitors salt concentration for saltwater pools and marine applications Specific Gravity (SG) (1.000-1.070): Measures water density for aquarium and hydroponic systems ORP (Oxidation Reduction Potential) (-1000mV to +1000mV): Indicates water sanitization effectiveness TDS (Total Dissolved Solids) (0-9990 ppm): Evaluates total dissolved particle content EC (Electrical Conductivity) (0-9999 μS/cm): Measures electrical conductivity for nutrient solutions Temperature (32°F-122°F / 0°C-50°C): Real-time temperature monitoring with automatic compensation
