Handheld TDS Meter with Case


The Handheld TDS Meter is a effective, compact way to test the quality of drinking water. Total dissolved solids (TDS) are the total amount of particles dissolved in a given volume of water, (measured in mg/L). This is also sometimes referred to as parts per million (ppm). In drinking water, these particles include mobile charged ions, minerals, salts, and metals. TDS is directly related to the purity of water and can therefore measure the quality of water purification systems.
