A TDS meter is a small hand-held device used to indicate the Total Dissolved Solids in a solution, usually water. Since dissolved ionized solids, such as salts and minerals, increa se the conductivity of a solution, a TDS meter measures the conductivity of the solution and estimates the TDS from that reading. Dissolved organic solids such as sugar and microscopic solid particles such as colloids, do not significantly affect the conductivity of a solution so a TDS meter does not include them in its reading. Use this to test the water quality prior to the job and if the TDS is above 20ppm we recommend using a water filter for your window cleaning job. Requires 2 x 1.5V LR44 Button cell batteries Show more
