7-in-1 water quality tester for aquariums and seawater: pH value, electrical conductivity, total solids, specific gravity, salinity, redox potential

7-in-1: Comprehensive Water Quality Measurement – This multifunctional meter precisely determines pH (0.0–14.0), electrical conductivity (EC: 0–10,000 µS/cm), total dissolved solids (TDS: 0–10,000 ppm), density (SG: 1.000–1.222), salinity (0–25% / 0–10,000 ppm), redox potential (ORP: ±999 mV), and temperature (0.0–60.0 °C) with integrated automatic temperature compensation (ATC). Detachable and Robust Sensor – Thanks to the detachable measuring head made of high-strength ABS, this device combines practicality, reliability, and durability – ideal for frequent use outdoors or in the laboratory. High Sensitivity and Guaranteed Accuracy – Thanks to advanced detection technology, the device delivers stable and reproducible results, even under demanding conditions (swimming pools, aquariums, hydroponics, or laboratory analyses). Easy-to-read, backlit LCD display – Clear, high-contrast digital display, perfectly readable even in dark environments or bright light (garden, basement, utility room). Versatile and adapted to French needs – Ideal for private swimming pools, greenhouses, freshwater and saltwater aquariums, drip irrigation systems, urban gardens, school laboratories, or home drinking water analysis.
