Professional TDS Testing — At Home or Lab
TDS testing determines the total amount of dissolved solids in your water (minerals, salts and other dissolved substances) and informs that your water is within a healthy, safe range. While a simple TDS meter provides a quick number, Volimy's expert TDS testing will give you an accurate reading, as well as information about what the number means, if it is a sign of a problem and what you should do in the future.
Understanding Your TDS Reading
| TDS Level (ppm) | What It Means |
|---|---|
| 0 - 50 | Very low — typical of RO/distilled water |
| 50 - 150 | Ideal range for most drinking water |
| 150 - 300 | Good, often indicates beneficial minerals |
| 300 - 500 | Acceptable but worth monitoring |
| 500+ | High — testing for specific contaminants recommended |
What Affects Your TDS Reading
Borewell and groundwater typically run higher in TDS than treated municipal supply.
A failing membrane lets more dissolved solids through, raising your reading over time.
TDS can shift after heavy rainfall or during dry months as groundwater composition changes.
Water sitting in metal tanks or old pipes can pick up additional dissolved minerals before it reaches your tap.
DIY Meter vs. Professional Testing
A meter and professional testing aren't competing options — most households use both. Keep a meter for regular checks; book a professional test when you see a concerning reading, notice a change, or need a verifiable report. Volimy sells TDS meters through Volimy Shop if you want one on hand.

TDS Testing Beyond Drinking Water
TDS testing isn't only for checking tap or RO water — it's also relevant for:
Aquariums — stable TDS is important for fish and plant health
Hydroponics — nutrient concentration is measured and managed via TDS
Borewell water — checking suitability before using for drinking or household use
Water business quality control — packaged water and RO plant suppliers testing output consistency
Testing Standards
TDS results are evaluated against IS 10500 (Bureau of Indian Standards), which sets 500 ppm as the maximum acceptable limit of drinking water and WHO guidelines on drinking water for reference areas. The report will explain how your reading compares the standards and is not only the numbers in your report.
How It Works
Book a home visit or lab-based test, depending on whether you want an instant reading or a fuller report.
Home visits give an on-the-spot reading; lab testing allows TDS to be assessed alongside other parameters in one sample.
