in 1 Electronic PH Meter for Swimming Pools, PH/TDS/SALT/SG/ORP/EC/TEMP/H2 Tester, Water Quality Tester for Swimming Pool, Spa, Aquarium, Drinking Wat

General description The 8 in 1 Electronic PH Meter is a versatile water quality tester designed for swimming pools, spas, aquariums, drinking water, and hydroponics. It can measure multiple parameters including salinity, specific gravity (SG), pH, hydrogen (H2), total dissolved solids (TDS), oxidation-reduction potential (ORP), electrical conductivity (EC), and temperature (TEMP). Technical specifications Measuring Range: Conductivity: 0-200,000 µS/cm TDS: 0-100,000 ppm Temperature: 0-60°C (32.0-140.0°F) Accuracy: ±2% Other information Auto Shutdown: The device automatically turns off after 5 minutes of inactivity to conserve battery life. Backlight: Features a large green backlit display for easy reading in low light conditions. Multi-mode Switch: Easily switch between TDS and conductivity, and between Celsius and Fahrenheit.
