The Best TDS Meters In India

Our bodies are majorly made of water, and hence, it is also one of the most critical commodities in our lives. Water is used everywhere in our daily lives. We need it for cleaning, cooking, watering the plants and the most important thing, staying hydrated. The problem in India is that you can’t drink regular tap water. It can be filled with impurities and pathogens. You need to have a water purifier to get safe drinking water at home. If there are more than dissolved impurities in the water, it can be harmful to your body. So, how do you check if the water is safe or not? One way to prevent the dissolved impurities in the water is with the help of the TDS Meter.

The TDS meter will enable you to check the quality of the water and ensure that there are enough minerals in the water for your body’s functioning. Still, it will also ensure that the minerals are not in excess, which may harm you otherwise.A higher value of TDS can indicate a problem with the water, and you should further test it for the presence of other minerals in the water. For example, a higher TDS value may mean that the water has higher levels of bromide, arsenic or sulfate. So, the TDS meter will give you an indicative impression of the water quality.

The next confusion would be which TDS meter you should buy. So, to help you further, we have listed some of the best available options in India. This will make it easy to buy a suitable TDS meter, but before we check out the best TDS meter in India, let us check out the safe TDS range.

What is the normal range of TDS for drinking water?

When you are checking the TDS of the drinking water, you will get a value. Now, you need to interpret that value and understand the quality of the water. To understand the normal range of TDS for drinking water, you can refer to the table below. This will give you an idea about the quality of your water. Depending on that, you can choose the water filtration solutions or clean the candle of the water filter.

TDS Range in PPM Water Quality
< 300 Excellent
Between 300&600 Good
Between 600&900 Fair
Between 900 &1200 Poor

How to Choose the Right TDS Meter?

Since there are so many different models of TDS meters available in the market, it becomes difficult to choose the right one. Each brand claims to be the best, and in such a case, you need to understand what you need. To help you select the proper TDS meter, we have compiled this short buying guide for you. Go ahead and check out the details below.

Technology Used – While purchasing the TDS meter, ensure that you are buying a TDS meter that uses a microprocessor for checking the TDS of the water. The microprocessors offer very accurate results, and they can measure the conductivity in a better way. The TDS is calculated depending on the conductivity, and hence the technology used in the TDS meter is critical. Ensure that you buy the TDS meter with the best of technology as that can impact the accuracy & precision of the TDS meter.

Battery Saving – There are times when you may leave the TDS meter on accidentally. In such a case, we are sure that you don’t want the battery to drain out and leave you stranded. So, the best way to save yourself from such a situation is to check if the TDS meter comes with a battery saving feature that will automatically turn off the TDS meter after a specific time.

Warranty – While going through the different models, we only found one option with a warranty. The brand offers a six-month warranty on that particular TDS meter. So, you can choose the model depending on the warranty policy. Even if you don’t want a warranty policy, that is alright. However, we want you to consider this aspect of the purchase as well.

Calibration – While looking for a TDS meter, ensure that you buy the pre-calibrated TDS meter. It is very tough to calibrate the TDS meter, so even if you have to spend a little extra, we advise you to buy the pre-calibrated TDS meter. This will save you a lot of work.

Price – We don’t think that the TDS meter price would bother you since it is usually priced between Rs 150 to Rs 300. In such a case, you can check what extra is offered by the TDS meter priced close to the higher range. The overall functionality remains the same, and there is little or no variation in the features of different models.

Travel Case – This may sound insignificant, but it is very important to have a travel case for your TDS meter. The travel case will protect the TDS meter from damage and help you carry it on your trips. We recommend opting for the TDS meter with a hard shell travel case since that offers better protection than the soft or fabric cases.

How to use TDS Meter?

Using the TDS meter is very easy. We have listed the steps below that you need to follow in order to use the TDS meter. Check them out below.

  • Start by filling the water in the glass and once you have it ready, remove the bottom cover of the TDS meter.
  • You will find an On/Off button on the TDS meter, and you need to click on that to move on to the next step. The screen should display 000 as soon as you turn on the TDS meter.
  • Now, you need to dip the tip of the TDS meter in the water. You need to ensure that you are only dipping the top or else, the water may damage the TDS meter.
  • You can use the hold button to stabilize the reading, and your job is done. TDS Meter should now display the reading on the screen of the TDS meter.
  • Remove the TDS meter, take the reading, dry the tip and turn it off before storing it back in the storage case.
