The ISPRING TDS meter is a digital instrument that measures the TDS (Total Dissolved Solids), in the scale of ppm (parts per million) which indicates the amount of solid dissolved in the water. The lower the TDS, the purer the water. EPA suggests that the TDS of drinking water should be below 500 ppm. Besides the purity, water temperature also impacts TDS value. ISPRING 3-button TDS meter features 2 sensors, 1 for TDS and 1 for temperature.
