FAQs – TDS meter

Q) Is TDS meter accurate?

TDS meters are used to measure the TDS that is present in the water through electrical conductivity and further converting them to PPM.

Hence, they are quite accurate with a margin of +- 3%.

Q) Is it harmful to drink low TDS water?

The water which lacks TDS is known to be a lot more corrosive and in the process, it can generate harmful metals such as copper or lead from the hardware and the plumbing pipes.

Hence, it is recommended that you drink water that has moderate TDS present in it.

Q) How much PPM is safe for drinking?

Any TDS water level below 500 PPM is considered very good for consumption purposes. However, the less the PPM, the better it would be concerning the health.

Q) How the TDS content present in water can be measured?

The TDS content that is present in water can be easily measured by the help of a TDS meter.

We have mentioned the list of some of the best TDS meters available in the market and thus you can select any one of them without having to worry about anything.

Q) What does a TDS meter indicate?

A TDS meter is a small hand-held device that indicates the Total dissolved solids present in water.

Dissolved ionized solids such as minerals and salts help in increases the solution conductivity.

Further, a TDS meter helps in measuring the solution conductivity and further, the TDS is estimated from the reading.


It is quite important to understand that the water we drink and the purification system that we use is effective such that safe and good quality of water is produced to drink.
