Description
General description This 3-in-1 Multifunction Digital Tester is designed to measure TDS (Total Dissolved Solids), EC (Electrical Conductivity), and temperature, making it an essential tool for monitoring drinking water quality, hydroponics, aquariums, and more. Please note that this device does not test pH levels. Technical specifications Net weight: 51g TDS range: 0-9990 ppm Conductivity range: 0-9990 µS/cm Temperature range: 32-176°F (0-80°C) Accuracy: ±2°C Size: 152×28×9 mm Usage Ideal for testing water purifiers, filters, swimming pools, SPAs, aquariums, and hydroponics. To use, peel off the electrode protective sleeves before use. Press the switch and immerse the electrode into the test solution. Wait for the numerical stabilization, then press the HOLD button to lock the reading before removing the electrode. Wipe the electrode before replacing the protective cover. To switch between TDS and conductivity, press the SHIFT button. To convert between Celsius and Fahrenheit, press
