pH-Meter für Wasser, 7-in-1, TDS-Wassertester pH/TDS/EC/ORP/Salz/SALT/SG/TEMP mit beleuchtetem Display, digitales pH-Meter für Trinkwasser, Aquarium

7-in-1 Water pH Meter: This digital water pH meter features seven functions, easily measuring pH, total dissolved solids (TDS), conductivity (EC), salinity, specific gravity (SG), oxidation-reduction potential (ORP), and temperature to assess water quality. It is suitable for various applications, including swimming pools, drinking water, marine aquaculture, ponds, and aquariums. Convenient Calibration and Automatic Temperature Compensation: This pH meter uses a three-point calibration method (pH: 4.00/6.86/9.18) and comes with three packets of calibration powder to ensure measurement accuracy (we recommend calibrating the pH with the calibration powder before first use). Automatic temperature compensation ensures stable readings under various temperature conditions. Easy Operation: Simply press the (Mode/Calibration) button on the pH meter to switch between pH, conductivity, total dissolved solids (TDS), salinity, specific gravity, and oxidation-reduction potential and read the values. Press and hold the HOLD/TEMP button to switch between temperature display and Celsius. This pH meter meets your daily water quality monitoring needs, allowing you to easily understand water quality conditions at any time. High-quality design: This pH meter features a backlit acrylic display screen, ensuring clear data readings even in low-light conditions. Removable design reduces replacement costs: the pH electrode can be easily replaced if the probe is accidentally damaged. 【7-in-1 pH meter, wide applicability】 Drinking water: pH 6.5-8.5, TDS less than 1000 ppm, typical conductivity between 50 and 1500 μS/cm, ensuring water purity; Swimming pool: Ideal pH 7.2-7.8, TDS 400-1500 ppm, water temperature 200-1500 ppm. Lifespan 5-25 years. Water temperature 2 to 9℃ (7-84.2℉). Marine aquaculture: pH 7.8-8.5, salinity 2.8%-3.5% (28-35 ppt), specific gravity 1.020-1.026 (25°C/77°F), oxidation-reduction potential +200 ~ +350 mV, to prevent stress to fish.
