Digital TDS Water Quality Tester

A pocket TDS meter so you can actually see what is in your tap, your filter output or your fridge water, instead of guessing.

How it works

TDS stands for total dissolved solids, the minerals, salts and metals left in water. The probe reads them in parts per million in seconds. Test before and after a filter and the drop in the number shows you the filter is doing its job, and tells you when it is time for a new cartridge.

Good to know

• Instant ppm reading for tap, filtered, RO, well or aquarium water
• Confirms when a filter is working and when a cartridge is spent
• Hold function freezes the reading; auto power-off saves the battery
• Compact and light enough to keep by the sink or take when traveling
