FAQS - Best TDS Meter In India 

 

1. What is a TDS meter and why should I use one at home?

A TDS meter (Total Dissolved Solids meter) is a compact device used to measure the concentration of dissolved substances in water. It's essential for Indian households to ensure water quality, especially when using RO purifiers. It helps you know whether your RO system is working effectively or needs servicing.

2. What is the ideal TDS level for drinking water in India?

As per BIS standards, the ideal TDS level for safe drinking water is between 50–150 ppm. Anything above 500 ppm may affect taste and health. Use a TDS meter to regularly check this and maintain water purity.

3. How often should I check the TDS level of my water?

It’s recommended to check your water’s TDS level once every 15–30 days, especially if you live in areas with hard water or industrial water supply. Regular checks help you identify if your RO service or filter replacement is needed.

4. Can a TDS meter detect harmful contaminants like bacteria or viruses?

No, a TDS meter only measures dissolved solids like salts and minerals. It cannot detect biological contaminants such as bacteria or viruses. For complete safety, combine a TDS meter with a UV or RO+UV water purifier and schedule regular RO service.

5. Is a higher TDS level always harmful for drinking?

Not necessarily. Some minerals are beneficial, but too high a TDS level can indicate the presence of harmful contaminants like arsenic, nitrates, or heavy metals. Always keep drinking water below 500 ppm, and choose a RO purifier based on your water source.

6. How do I know if my TDS meter is accurate?

Choose a pre-calibrated TDS meter with automatic temperature compensation (ATC) for accuracy. Trusted brands like Konvio Neer, Octus, and Ocean Star are known for their reliable readings. Also, cross-check readings periodically with lab results or during your best RO service in India.
