Frequently Asked Questions

1. How a TDS meter is used to higher accuracy?

TDS meter is similar to a thermometer in terms of looks, but the working is totally different. You need to place TDS meter into the water, and the sensor inside this small meter starts taking some samples. By placing the meter ten seconds into the water, you will get to know about the percentage of mineral content, metals, and other contaminants.

Some TDS meter mentions the treatment method required to make water drinkable. A range of manufacturers are offering TDS meter, and all of them follow a similar method to check the water sample. However, if you buy a smart or advanced product, then there will be few differences in the sample taking process only.

2. What are the common uses of TDS meter?

TDS meter not only provides essential data for home use, but these are also used in industries. There are a total of four major criteria where you can find the use –

  • To check the efficiency of the commercial filtration system.
  • To check the effectiveness of the membrane in the reverse osmosis system.
  • They are ensuring the credibility of a common household water purifier.
  • They are checking water habitats contamination levels at natural resources.
  • They determine the salt level in hydroponic systems.

Apart from these uses, a TDS meter is also used by the traveler to ensure that they are drinking clean and purified water from natural habitats such as rivers and ponds.

3. What’s the Acceptable TDS Level?

The acceptable TDS level depends upon the purpose, and if you want to ensure whether the water is drinkable or not, then you should be checking the TDS level. If the level is below or equal to 500 parts per milligram unit of water, then it is drinkable. If the number exceeds, then you should use a water purifier to ensure safety.

According to research, most of the water habitat is above 500ppm per unit in India. Getting a high-end water purifier can help, but if the water is clean and doesn’t require any treatment, then you can avoid the purchase. A simple TDS meter is always effective in such cases, and it always feels highly reliable.

Make sure that you don’t drink water that exceeds 1000ppm because it is totally unsafe, and there is too much contamination to make you sick under a couple of days.  

4. Are TDS meter and PPM meters the same?

If you use a TDS meter to learn about the contamination level, you can find that it provides results in part per million, which is PPM. Due to this, PPM meter is an alternative name, and both are the same things. You are going to check iron, metal, and another type of minerals into the water by dipping a TDS meter into water.

It takes a small sample and provides results in PPM. In some cases, you can find several other ways to calculate PPM, but they aren’t accurate as a TDS meter, so you should stay careful during the use to find out the perfect solution.

5. Are TDS meters accurate?

Most of the TDS meter has a range mentioned by the manufacturer, and it allows you to understand how adequate the results are. Reputed manufacturers offer 99.99% accurate TDS meter, which means that they are roughly close to the accurate number. A small difference isn’t that bad, and it is acceptable.

However, if you choose a cheap TDS meter, then you might find a huge fluctuation in results. There are several ways to test a TDS meter, and you can try them to ensure the effectiveness and accuracy of any other option. Keep it in mind that you look after manuals before getting started with the use because manuals will help you get highly accurate results.

6. How to Calibrate TDS Meter?

To calibrate the TDS meter, you need distilled water, which should be about 0 ppm. However, you can do the calibration with some fluctuated number. One thing worth learning is, distilled water isn’t the same for every brand. You can buy distilled water bottles and find a difference in terms of ppm. Due to this reason, you should be looking for adequate distilled water before getting started.

Conclusion:

The digital TDS meters are handy equipment that can help you check the quality of water in your house or the efficiency of the purifier that you are using in the house. You can be sure whether you are consuming healthy water or not. Also, due to its ease of use, you can handle it very easily. There is no doubt that TDS meters will help you drink the right water, but choosing the right TDS meter is very important. The digital TDS meters mentioned in this article are definitely good to go, but depending on your choice, your requirement and your budget, you can pick the right one for your house.
