TDS Meter: Your Pocket-Sized Water Quality Checker in 2025
Introduction
Ever wondered what is really in your drinking water? That clear-looking glass could be hiding dissolved salts, heavy metals, or even industrial chemicals. And while it may taste fine, is it really safe? That’s where a TDS Meter comes in — your tiny water detective that gives instant answers. We are diving deep into what a TDS Meter is, how it works, why you need one in 2025, and how to use it the right way. Whether you’re managing an RO system at home or running a water treatment plant, knowing your TDS is a game-changer.
💧 What is TDS? Total Dissolved Solids (TDS) Explained -TDS stands for Total Dissolved Solids – all the organic and inorganic stuff dissolved in water, including minerals, salts, and metals. These can come from natural sources or industrial runoff.
What Makes Up TDS?
Calcium
Magnesium
Sodium

Sulfates
Heavy metals (lead, arsenic)

🔍 What is a TDS Meter?
A TDS Meter is a small handheld device that tells you how many dissolved solids are in your water usually measured in parts per million . It’s super easy to use – dip it in water and within seconds you get a reading.
⚙️ How Does a TDS Meter Work?
TDS meters work on the principle of electrical conductivity. The more dissolved ions (charged particles) in your water, the better it conducts electricity.
Here’s what happens inside:
Two electrodes dip into the water.
They pass a small current between them.
The resistance is measured and converted into TDS value .
📊 Ideal TDS Levels for Drinking Water
According to BIS (Bureau of Indian Standards) and WHO (World Health Organization), these are the ideal ranges:
TDS Level (ppm)
Water Quality
0 – 50
Deionized/Pure – Not suitable for drinking
50 – 150
Excellent
150 – 300
Good
300 – 500
Fair
500 – 1000
Poor – Not ideal
