A TDS meter (also known as a ppm pen or nutrient tester) is a convenient digital tool for instantly checking overall water quality TDS stands for Total Dissolved Solids, which includes any salts, metals, or minerals present in the water. The meter displays your water purity level in ppm (parts per million) with just a push of a button The lower the TDS level, the purer the water, with 0 ppm indicating pure H2O. This meter is ideal for assessing tap water quality and determining when to change filters (note: it does not test for biological contaminants) This rugged TDS meter comes with a protective carrying case. The temperature button allows you to measure water temperature, with an accurate reading achieved after 1-2 minutes for temperature compensation Popular among both industry professionals and household users, this handheld TDS meter is versatile and user-friendly
