Interesting Facts About TDS Testers
TDS testers are widely used in environmental monitoring and household water safety checks because they measure the dissolved solids that can affect taste, purity and filtration performance. Higher TDS values may indicate minerals, salts or contaminants in the water, while lower values suggest cleaner and more purified water. Alloy probes provide greater stability compared to traditional metal sensors, ensuring more consistent and long-lasting accuracy.
