The exception to the use of the TDS meter is a water softener, this is due to the specificity of the tester's operation. Salt tablets are used in softeners, the meter does not distinguish ions, but counts and sums them. So the measurement of contamination behind the softener will be higher than before.
Other methods of measuring water hardness are used at the output of the softener, e.g. droplet/strip water hardness testers.

- Remove the protective cap. Turn on the meter with the "ON/OFF" button
- Immerse the meter in the test liquid (do not cross the immersion line - the height of the protective cap).
- Wait until the displayed value stabilizes (less than 5s), then read the value from the display or press the HOLD button and read the result away from the measured liquid.
- After the measurement is completed, wipe the electrode with a cloth. Turn off the meter with the "ON/OFF" button. Put on a protective cap.
Pressing the MODE key allows you to choose between 4 display modes:
- TDS - ppm
- EC - µs/cm
- °C
- °F

ATC function (Automatic Temperature Compensation) - temperature measurement and compensation indication of the meter in the range of 0-50°C. This gives us a more accurate result.
The TDS&EC meter complies with EU directives and is marked with the CE mark. In addition, the meter is made of materials that meet the strict requirements of the EU ROHS directive.
- Do not immerse the meter in the solution above the immersion line to avoid damaging the circuits.
- Temperature: TDS meter cannot be used to measure high temperature water.
- Flow rate: The TDS meter cannot be used to measure water during its flow.
- The protective cap can be used as a handheld measuring container.
The TDS meter is an easy-to-use tool for quickly and accurately indicating the number of dissolved solids in liquids. Dissolved solids are mostly inorganic salts such as sodium, calcium, magnesium and potassium cations along with chlorides, bicarbonates, carbonates, phosphates, sulfates and nitrate anions.
The higher the measurement value (hard water), the worse the absorption of water by the body's cells and the greater the likelihood of its negative impact on human health
According to Polish standards, water above 500 ppm is not suitable for drinking.
The exception to the use of the tester is a water softener, which results from its specificity of operation. Salt tablets are used in softeners, the meter does not distinguish ions, but counts and sums them. Thus, other methods of measuring water hardness are used at the output of the softener, e.g. Striped water hardness testers
TDS meters measure EC (electrical conductivity) of liquids. Dissolved salts and minerals conduct electricity, the more minerals in the water sample, the higher the conductivity. The meter then converts the EC reading to TDS using the appropriate conversion rate.
High levels of TDS may indicate a large amount of organic material in the water and a lower ability of water to retain oxygen. This means that water changes are required, even if nitrate levels are low.
High concentrations of TDS can reduce water clarity, contribute to reducing photosynthesis, combine with toxic compounds and heavy metals, and lead to an increase in water temperature.
