1.3 in Digital Water Tester (TDS / EC / Temp) Why you need it Quickly verify water quality for drinking, aquariums, hydroponics, appliances, and lab work. The tester identifies dissolved solids and conductivity and shows water temperature so you can act before problems develop. Compact and portable for spot checks at home, in the field, or in a workshop—no complex setup required. Key features and benefits Measures TDS (total dissolved solids), EC (electrical conductivity), and temperature in one compact device. 1.3inch upgraded LCD screen with autolock function for clear, stable readings you can record or compare. precision probe and sensor deliver consistent PPM readings across 0–9990 ppm with ±2% accuracy. Factorycalibrated for immediate use—no manual calibration needed out of the box. Auto poweroff after 5 minutes of inactivity to conserve battery life. Displays temperature in Celsius or Fahrenheit (0.0–88.0 °C / 32.0–176.0 °F). Lightweight and pocketable: 57 g and dimensions 30 × 15 × 155 mm for easy transport and storage. Practical applications Drinking water: Confirm RO system performance or test tap water after filter changes to ensure safe drinking standards. Hydroponics and gardening: Monitor nutrient solution concentration to keep plant feeding consistent and avoid over or underdosing. Aquariums: Check water quality before adding fish or adjusting treatments to protect aquatic life. Also suitable for laboratory spot checks, industrial rinsewater testing, and general household water monitoring. What it delivers Fast, reliable readings that help you troubleshoot filtration issues, control nutrient levels, and protect aquatic environments.
