One touch and know how pure is the water.
The AquaTester measures the purity of water providing the TDS (Total Dissolved Solid) values in ppm unit.

It does not recommend any value as the best for drinking water or other uses (ask your doctor for drinking water or a professional staff for other uses)


1. Taste/Health High TDS results in undesirable taste which could be salty, bitter, or metallic. It could also indicate the presence of toxic minerals. The EPA's rescommended maximum of TDS in water is 500mg/L (500ppm).

2. 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.

3. Hardness - High TDS indicates Hard water, which causes scale buildup in pipes and valves, inhibiting performance.

4. 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.

5. Hydroponics TDS is the best measurement of the nutrient concentration in a hydroponic solution.

6. Pools and Spas TDS levels must be monitored to prevent maintenance problems.

7. Commercial/Industrial High TDS levels could impede the functions of certain applications.

8. Colloidal Silver Water TDS levels must be controlled prior to making colloidal silver.
