Product Description –Ez-9908/686 4-in-1 Water Quality Tester The Ez-9908/686 4-in-1 Water Quality Tester is a portable digital water quality meter designed to measure multiple parameters in a single handheld device. It is commonly used for drinking water testing, aquariums, hydroponics, pools, and water treatment systems. It combines four key measurements: * EC (Electrical Conductivity) * TDS (Total Dissolved Solids) / Salt * Ph * Temperature This makes it a multi-parameter analyzer for quickly assessing water quality. ⸻ ⚙️ Key Features * 4-in-1 functionality: Measures EC, TDS, ph, and temperature in one device * Pen-type portable design: Easy to carry and use in field testing * Digital LCD display for real-time readings * Waterproof (IP67) design in many variants * Auto Temperature Compensation (ATC) for accurate readings * Data hold function to freeze readings on screen * Auto power-off to save battery after inactivity ⸻ Measurement Parameters & Ranges 1. EC (Electrical Conductivity) * Measures water’s ability to conduct electricity (indicates dissolved ions/salts) * Typical range: * 0 – 10,000 µS/cm * Extended ranges up to 400 mS/cm ⸻ 2. Ph * Measures ph range in water * Range: * 0-14 ⸻ 3. TDS (Related to Salt Content) * Indicates total dissolved substances (minerals, salts, impurities) * Range: * 0 – 10,000 ppm ⸻ 4. Temperature * Measures water temperature for accurate compensation * Range: * 0.1°C – 60°C * Accuracy: about ±0.5°C
