7-in-1 Aquarium Water Quality Tester – Measures pH, TDS, EC, ORP, salinity, and density – Precise and reliable, no batteries or test kits required – Video available

Customizable measuring range function: This pH/EC/ORP tester allows you to freely define maximum and minimum limits for each parameter (pH, electrical conductivity, redox potential). As soon as the measured value leaves the predefined range, the display automatically turns red – an immediate and intuitive visual warning, ideal for precise monitoring in aquaculture, swimming pools, or hydroponics. Backlit display with wireless smartphone control: Equipped with an easy-to-read LCD screen with integrated backlighting and Bluetooth 5.2 compatibility, this tester synchronizes in real time with your mobile app (iOS & Android). This allows you to monitor, adjust, and export your data from anywhere – even in dark or humid environments. Highly sensitive and modular electrode tip: The high-precision tip sensor is removable and replaceable. This ensures a long service life and consistent reliability, even after multiple calibrations. Easy immersion in solutions enables fast and reproducible measurements, even with samples of low conductivity. Automatic data storage and easy sharing: All measurements are automatically saved on the device and transferred to the mobile app. You can then export your measurements to Excel or share them directly with colleagues, customers, or partners – a feature highly valued by water quality professionals and water treatment technicians. Simultaneous real-time display of multiple parameters: Simply immerse the probe in the solution: pH, electrical conductivity (EC), total solids (TDS), salinity, specific gravity (SG), redox potential (ORP), and temperature are instantly and simultaneously displayed on the screen and in the app – without any extra steps, without wasting time, and for optimal daily efficiency. Extended measuring range and professional accuracy: pH (0.00–14.00, resolution 0.01, accuracy ±0.05), EC (0–9990 µS/cm / 10.01–19.99 mS/cm / 20.1–200.0 mS/cm), TDS (0–999 ppm / 1000–9990 ppm / 10.1–100.0 ppt), salinity (0.01–25.00 %), ORP (−1200 to +1200 mV), temperature (0.1–60.0 °C), with 3-point calibration (pH: 4.00 / 6.86 / 9.18 or 4.00 / 7.00 / 10.01) – everything you need for reliable analysis in laboratories, greenhouses or municipal facilities. Package contents: 1 × pH/EC/ORP tester, 1 × multilingual instruction manual (French included), batteries not included (3 × LR44). This product is sold by xiaosong on behalf of a third-party seller.
