What is TDS?

 As rainwater passes through the ground it collects solids such as minerals, rocks, and much other material on the surface. The solids that rainwater collect some dissolve in water and others suspended. The solid that is dissolved is the one we call TDS and the one suspends are called TSS (total suspended solids).

TDS is a short name for the total dissolved solids in a particular volume of water.

Dissolved solid are organic and inorganic matters dissolved in water. Inorganic material contains magnesium, potassium, sodium, chloride, and sulfates while organic matter includes plant matter, silt, plankton, and industrial waste and sewage.

Also, other solids in water come from chemicals used in water treatment plants, agricultural activities, industrial waste, sewage, residential waste, piping, and plumbing used to transport water.

The TDS level varies from one area to another some areas have high levels of dissolved minerals and others have low levels.

The areas with a high level of minerals make your water hard and with a low level become acidic because important minerals are removed.

Knowing the TDS level of your water is important because you will know if your water is healthy for human consumption/ help you know the quality of your water.

The best way to test your drinking water TDS level is by using TDS meter

The device-detect dissolved solids, conductivity and temperature in parts per million (ppm) Where TDS meter is applicable

Tds meter is used to test the quality of water in the aquarium, hydroponics, fish tank, swimming pool, and drinking water

If you are using a reverse osmosis system and you want to know whether the membrane is working effectively you need a TDS meter to test your water

Why worry about water TDS level

TDS in water do not pose any health hazard but cause your water to taste bad and affects house appliances.

For example, water with a high concentration of TDS tastes salty, fade your clothes, make your hair dull, cause scale build-up on the plumbing and houses. In short, it is the one people call it hard and has so many negative effects.

Water with low TDS causes you water acidic which is not good for human consumption but can be used for cleaning.

Which is better TDS meter or water testing strips

The water testing strip measures exact contaminants in your water while TDS meter does not measure contaminants in water but tells you whether your water is the quality/healthy.

If you want to decide the best water filter or softener to purchase you need to test your water using a water testing kit and not TDS meter.

How to store TDS meter

  • After you are done using always rinse with distilled water
  • Dry it off  
  • Return the protective cap and store in a dry place
  • Store in the convenient carrying case if any

How do you measure water TDS?

Water TDS levels are measured in parts per million (ppm).
If TDS level is between 50-150 ppm/ less than 300 mg/l that is excellent for drinking
