Total Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, inorganic salts or metals dissolved in a given volume of water, these elements are usually calcium, magnesium, sodium, and potassium cations and carbonate, hydrogencarbonate, chloride, sulfate, and nitrate anions. TDS is directly related to the purity of water and the quality of water purification systems.

The presence of Total Dissolved Solids may affect the taste of water. The palatability of drinking water has been rated by panels of tasters in relation to its TDS level as follows**:

excellent, less than 300 mg/litre;
good, between 300 and 600 mg/litre;
fair, between 600 and 900 mg/litre;
poor, between 900 and 1200 mg/litre; and
unacceptable, greater than 1200 mg/litre.
water with extremely low concentrations of TDS may also be unacceptable because of its flat, insipid taste.

(** source: WHO Guidelines for Drinking Water Quality, Total Dissolved Solids in Drinking Water)

The EPA* Secondary Regulations advise a maximum contamination level of 500mg/litre (=500 parts per million (ppm)) for TDS. When TDS levels exceed 1000mg/l it is generally considered unfit for human consumption. A high level of TDS is an indicator of potential concerns, and warrants further investigation. Most often, high levels of TDS are caused by the presence of potassium, chlorides and sodium. These ions have little or no short-term effects, but toxic ions (lead arsenic, cadmium, nitrate and others) may also be dissolved in the water.

Water purification system, like Reverse Osmosis systems require regular monitoring for TDS to ensure the filters and/or membranes are effectively removing unwanted particles and bacteria from your water.

*EPA = US Environmental Protection Agency

Benefits of testing for TDS:

Taste/ Health: High TDS results in undesirable taste which could be salty, bitter, or metallic. It could also indicate the presence of toxic minerals.
Filter performance: Test your water to make sure the reverse osmosis or other type of water filter or water purification system has a high rejection rate and know when to change your filter (or membrane) cartridges.
Hardness: High TDS indicates Hard water, which causes scale buildup in pipes and valves, inhibiting performance.
Aquariums/Aquaculture: A constant level of minerals is necessary for aquatic life. The water in an aquarium or tank should have the same levels of TDS and pH as the fish and reef's original habitat.
Pools and Spas: TDS levels must be monitored to prevent maintenance problems.

These TDS water quality test strips are easy to use and designed to eliminate the need for breakable meters that require calibration:

Simple Dip-Wait-Read Testing Method
Test strips are stored in a plastic container with a detailed colour chart to protect them
Ideal for quick and reliable testing of water
Accurate results are achieved in under one minute
This product is safe and easy to use since there are no chemicals to mix, an MSDS is not required
Factory-calibrated water quality test strips

Test procedure:

Dip one test strip into water sample for 2 seconds.
Remove strip and shake once briskly to remove excess sample.
Wait 10 seconds and match colour with closest on colour chart. Complete colour matching within the next 20 seconds.

Sensititvity: <50, 100, 250, 500, >750 mg/l (ppm)

Total testing time: 32 seconds

Content: 50 test strips

Please note: Store in a cool, dry (below 32°C) place and away from excess heat and direct sunlight. No MSDS required. Keep away from children and pets. Avoid contact of test areas on strips with skin & eyes, do not ingest or expose to acids.
