General description The Digital Water Tester is a versatile 3-in-1 device designed to measure Total Dissolved Solids (TDS), conductivity, and temperature in various water sources. It is suitable for use in aquariums, swimming pools, and hydroponic systems, providing reliable readings to help you monitor water quality effectively. Technical specifications Test Function: Conductivity / Total Dissolved Substances (TDS) / Temperature Accuracy: +/-2% Test Range: Conductivity 0-9990 µS/cm TDS: 0-9990 ppm Temperature: 0.1-80 °C (32.0-176.0 °F) Size: 150 x 20 mm Material: Plastic + Metal Installation No calibration or setup is required; it can be used right out of the box. Simply soak the TDS meter in the water sample and stir to get results in seconds. Usage Check the total dissolved solids or electrical conductivity in various water sources. Determine the efficiency of reverse osmosis (RO), deionization (DI), or distillation units. Monitor nutrient levels in hydroponic systems. Other
