LOOKS CAN BE MISLEADING

Clear Water Doesn’t Tell The Whole Story

Two glasses of water may look identical while producing very different dissolved-solids readings. This meter makes those differences easier to compare.

Comparing TDS readings in clear water
Use real readings—not appearance alone—to compare tap water, filtered water and other water sources.

FAST AND EASY TO USE

Test Water In 3 Simple Steps

No test strips, mixing solutions or lengthy setup. Dip the probe, allow the reading to stabilize and view the result.

How to use a digital TDS meter
1

Remove The Cap

Take off the protective cap and turn on the meter.

2

Dip The Probe

Place the testing end into the water without exceeding the recommended immersion line.

3

Read The Result

Wait briefly for the value to stabilize, then use the Hold function if needed.

MORE THAN ONE READING

Understand More About Your Water

Switch between useful measurement modes to compare dissolved-solids concentration, electrical conductivity and water temperature.

TDS EC and water temperature measurement modes

TDS / PPM

Displays the estimated concentration of total dissolved solids in parts per million.

EC

Measures electrical conductivity to help compare ion concentration between water samples.

Temperature

View the current water temperature for more informed testing and maintenance.

Hold Function

Freeze the displayed value so it is easier to read after removing the meter.

TRACK FILTER PERFORMANCE

Compare Water Before And After Filtration

Compare readings from unfiltered and filtered water to observe how your filtration system is performing over time.

Comparing TDS before and after water filtration

Monitor Changes

Record readings periodically and compare them over time.

Check Your System

See whether filtered-water readings are changing from their usual range.

Make Informed Decisions

Use the results alongside your filter manufacturer’s replacement recommendations.

IMPORTANT TO UNDERSTAND

What A TDS Reading Can—and Cannot—Tell You

TDS indicates the estimated amount of dissolved substances in water. It is useful for comparing water samples and monitoring changes, but a low reading does not automatically prove that water is safe to drink.

TDS meters do not identify specific contaminants. They do not directly detect bacteria, viruses, pesticides, lead or other individual substances. Use certified laboratory testing or appropriate specialized test kits when safety or contamination is a concern.

GOOD TO KNOW

Frequently Asked Questions

What does TDS mean?

TDS stands for Total Dissolved Solids. It estimates the concentration of dissolved ions and substances in water and displays the result in PPM.

Can this meter tell me whether water is safe to drink?

Not by itself. The meter can help compare dissolved-solids readings, but it cannot detect every contaminant or determine complete drinking-water safety.

Can I use it to check my water filter?

Yes. Testing water before and after filtration can help you observe changes in TDS readings. Always follow the filter manufacturer’s replacement schedule as well.

Does it measure pH?

No. A separate pH meter or pH test kit is required to measure acidity and alkalinity.

Can it measure water hardness?

TDS may reflect dissolved mineral content, but it does not provide a direct hardness measurement. Use a dedicated hardness test for accurate calcium and magnesium results.

How should I clean the probe?

Rinse the probe with clean water after testing, gently shake off excess moisture and replace the protective cap after the probe has dried.

Can I immerse the entire meter?

No. Immerse only the probe area to the level specified in the user manual. Keep the screen, buttons and battery compartment dry.
