Ensure precise and comprehensive water quality analysis with this advanced 7-in-1 Water Quality Tester, crafted from durable ABS material for reliable use. Designed for professionals and enthusiasts alike, this multifunctional device measures pH, ORP, EC, total dissolved solids (TDS), SALT, specific gravity (S.G), and temperature, delivering accurate results across a wide range of applications. Featuring temperature compensation technology, it guarantees consistent accuracy even in varying environmental conditions, while the large digital display provides clear and easy-to-read measurements. Key Features: · Multifunctional 7-in-1 Testing Capability: Accurately measures pH (0.00-14.00), ORP (-2000mV to 2000mV), EC (0-19900 µS/cm and 0-199.0 mS/cm), total dissolved solids (0-19900 ppm and 0-199.0 ppt), SALT (0-199.0 ppt and 0%-20%), specific gravity (0.990-1.400), and temperature, making it a versatile tool for comprehensive water quality assessment. · High Accuracy with Temperature Compensation: Ensures precise readings with pH accuracy of ±0.03 pH, ORP ±5 mV, EC, TDS, SALT ±2% F.S, and temperature ±1.0°C, supported by automatic temperature compensation from 0°C to 50°C for reliable results under different conditions. · Dual Calibration Methods: Supports two calibration methods for pH values including 6.86, 4.01, 9.18, 7.00, 4.00, and 10.00, enhancing measurement accuracy and adaptability. · Bluetooth Connectivity & Data Export: Compatible with iOS and Android devices via the Tuya app, enabling real-time data transmission within a 10-meter range. Easily export data via email at customizable intervals (hourly, daily, weekly, monthly) for convenient monitoring and record-keeping. · Auto Power Off & Reconnect: Features an intelligent auto-off function that powers down and disconnects Bluetooth after 8 minutes of inactivity, with automatic reconnection upon testing to save battery and enhance user experience. · Multilingual Support: Includes multiple language options such as Chinese (Traditional), English, French, German, Russian, Japanese, Korean, and Spanish, ensuring accessibility for users worldwide. · Portable & Lightweight Design: Compact size (18 cm / 7.1 in) and lightweight (approx. 192g / 6.8oz) for easy handling and transport, powered by 4 AG13 button batteries (not included).
