Handheld Water Quality Tester

The Zero Water TDS Meter measures detectable dissolved solids in drinking water and displays the reading on a built-in screen. It includes a temperature function so users can check water temperature at the same time. The device is designed for quick spot checks at home or while travelling.

Owners of Filter Jugs and RV Travellers

This meter suits anyone who wants to verify filter performance or compare different water sources before use. It is not intended for laboratory-grade analysis or continuous inline monitoring. Buyers needing certified calibration records or data logging should look at dedicated instrumentation.

Replacement Trigger at 006 Reading

Questions about this item

What water source do I need to test with this meter?

The meter measures detectable dissolved solids in any water sample you provide, letting you compare different sources such as tap, filtered, or bottled water.

Will this meter still work if I keep using my older filter cartridge?

Yes, the meter reads total dissolved solids regardless of filter age; a reading above 006 signals that the older cartridge should be replaced.

How do I confirm the meter is giving accurate readings after I turn it on?

Dip the probe into water and check that the display shows a stable TDS value; a reading above 006 indicates the filter needs changing, confirming the meter is functioning.
