4-in-1 Bluetooth Water Quality Tester: pH value, electrical conductivity, total solids content, temperature – No battery or test kit required

Bluetooth 5.2 wireless connection: This high-performance pH meter features a stable and fast Bluetooth connection (version 5.2) for seamless synchronization with the mobile app – ideal for demanding professionals and hobbyists. Intelligent full-screen display: Clear and easy-to-read display for a quick overview; complete remote control via smartphone – touchless operation for an intuitive and modern user experience. Real-time synchronization via the mobile app: Simply immerse the probe in the solution – pH, EC, TDS, and temperature are instantly and simultaneously displayed on your smartphone, including historical data and trend graphs. Ergonomic and highly practical design: Designed for fatigue-free everyday use: no repetitive settings, no frequent manual operation – reliable, fast, and effortless measurements. Highly sensitive, corrosion-resistant glass electrode: Removable, robust, and precise probe for a long service life, even in aggressive environments (salt water, nutrient solutions, wastewater, etc.). Extended measuring range and laboratory accuracy: pH (0.00–14.00, resolution 0.01, accuracy ±0.05 pH) / conductivity (0–9999 µS/cm, 10.01–19.99 mS/cm, ±2 % FS) / total solids content (0–9990 ppm, ±2 % FS) / temperature (0.1–60.0 °C, ±0.5 °C). Simplified calibration and automatic compensation: Simple 1-, 2-, or 3-point calibration (pH: 4.00 / 6.86 / 9.18 or 4.00 / 7.00 / 10.01; conductivity: 1413 µS/cm or 12.88 mS/cm) with automatic temperature compensation (0.1–60 °C). Reliable power supply and lightweight design: Operates on 3 LR44 batteries (not included), ultra-lightweight (167 g), compact dimensions (187 × 37 mm) – ideal for outdoor use, in greenhouses, or in mobile laboratories. Versatile applications: Perfect for aquariums, swimming pools, hydroponics, drinking water and wastewater treatment, organic farming, aquaculture, veterinary pharmaceuticals, and laboratory quality control.
