TDS

TDS stands for total dissolved solids and is a general measure of water quality.  It is used as an indication of aesthetic characteristics of drinking water and as an aggregate indicator of the presence of a broad array of chemical ingredients. Total Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water, expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million (ppm). TDS is directly related to the purity of water and the quality of water purification systems and affects everything that consumes, lives in, or uses water, whether organic or inorganic, whether for better or for worse.

The TDS-3 Water Tester is to monitor the effectiveness of the RO Membrane and ideal for commercial and domestic use.

Simply pour a glass of water, turn on the TDS meter and place it into the glass and the reading will appear. The TDS meter is ideal for keeping track of the effectiveness of your water filter and knowing when to replace the filters.

What Are Total Dissolved Solids?

"Dissolved solids" refer to any minerals, salts, metals, cations, or anions dissolved in water. This includes anything present in water other than the pure water (H20) molecule and suspended solids. (Suspended solids are any particles/substances that are neither dissolved nor settled in the water, such as wood pulp.)In general, the total dissolved solids concentration is the sum of the cations (positively charged) and anions (negatively charged) ions in the water. Parts per Million (ppm) is the weight-to-weight ratio of any ion to water.A TDS meter is based on the electrical conductivity (EC) of water. Pure H20 has virtually zero conductivity. Conductivity is usually about 100 times the total cations or anions expressed as equivalents. TDS is calculated by converting the EC by a factor of 0.5 to 1.0 times the EC, depending upon the levels. Typically, the higher the level of EC, the higher the conversion factor to determine the TDS.

NOTE - While a TDS meter is based on conductivity, TDS and conductivity are not the same things.
