Digital TDS Meter | Water Contaminant Tester

TDS stands for Total Dissolved Solids — the measurement of inorganic salts, heavy metals, minerals and other dissolved particles in your water. The lower the TDS reading, the purer the water.Australian tap water typically reads between 50-500ppm depending on your location and water source. Filtered water should read significantly lower. But most people have no idea what their actual TDS level is — they just assume their filter is working.The Biorhythm Digital TDS Meter tells you exactly what's in your water in seconds. Dip the probe, read the ppm on the LCD display. Use it to verify your water filter is actually working, compare tap water versus bottled water, or monitor water quality over time.At $29.95 it pays for itself the first time you discover your filter isn't performing as it should
