💧 Comprehensive 9-in-1 Analysis: This compact pen-style device provides a "complete picture" of water health by measuring chemical indicators (COD, TOC, UV275), physical solids (TDS, EC, Salinity, Hardness, Specific Gravity), and Temperature.
💧 Dual-Detection Technology: It utilizes two distinct scientific methods for accuracy: the UV absorbance method to detect organic pollutants and electrical conductivity to calculate mineral content and salinity.
💧 Instant Visual Feedback: The device features an intelligent scoring system with a color-coded LCD backlight. It translates complex data into four easy-to-read categories—Excellent, Good, Fair, or Poor—allowing for immediate assessment at a glance.
💧 Precision and Reliability: Built for accuracy, the tester includes a high-sensitivity probe and automatic temperature compensation, ensuring stable readings even if the water temperature fluctuates between 0–50°C.
💧 Versatile and User-Friendly: Designed for simple one-button operation, it is suitable for a wide range of applications, including testing drinking water, groundwater, saltwater aquariums, and aquaculture, making professional-grade insights accessible to homeowners and hobbyists alike.
