6 Best TDS Meter to Buy {Reviews & Buying Guide}

Along with filtering the impurities, the purpose of a water filter is to maintain the right amount of dissolved minerals in the water. Suppose a high amount of unwanted minerals are harmful to the body. In that case, a meager quantity of minerals in water can be precarious for our bodies.

Discussing this in more technical terms, it is called TDS. TDS stands for Total Dissolved Solvent, which means total dissolved solids or solvents in the water.

The dissolved solids generally represent the cations, anions, metals, salt, and minerals dissolved in the water. The total dissolved solvent typically comprises magnesium, calcium bicarbonate sulfates, chlorides, sodium, potassium, organic salt, and an inorganic salt, influencing water quality.

Your water needs to have the right balance of these solvents. Hence, people use the TDS meter to monitor water quality and dissolved solvents.

In this article, we will walk you through some of the best TDS meters that you can vouch for the performance to supply the right amount of TDS. But before that, let’s understand what a TDS meter is and how does it work?

What is a TDS Meter, and How Does it Work?

The dissolved solvents generally originate from the natural origin of the water, like sewage, industrial wastewater, chemical treatment, urban runoff, piping, and the tanks that supply the water to every house.

The water comprising such chemicals is not appropriate for drinking or showering, so people use TDS meters to check their level. This is also known as the TDS tester for the TDS sensor.

The TDS meter is a device that is responsible for giving the contamination level or the level of total dissolved solids present in the water.

According to the EPA (Environmental protection agency), drinking water should contain less than 500 mg per liter of total dissolved solids. The same range is considered a standard range for total dissolved solids in most countries. Besides the TDS meter, several laboratory tests can be performed to find the contamination level.

How Can You Get a TDS Meter?

Buying a TDS meter is the easiest and best way to own a TDS meter. It gives you lots of options to choose from and is a much more accessible and efficient way to get it fast. Plenty of affordable TDS meters are available in the market, which provide a range of other benefits.

Apart from buying it, the municipality department of a particular area is also responsible for distributing it to the population. But owning a government TDS meter is a very hectic and tedious job.

The user has to visit the government organization repeatedly to get the TDS meter fixed at their home. So, it is better to order it online, as it will not cost you more.

Things to Consider Before Buying TDS Meter

If you are considering investing in a particular TDS meter ( mentioned above or not),  you should always evaluate certain factors that will help you throughout the process. These factors will help during the buying process and protect you from difficulties. These factors are listed below:

The Battery Saving Feature

The battery is essential for a TDS meter and works as a life to this tool. This product works on the battery, and when you extensively run it, it will automatically exhaust battery life, limiting the life span of the meter.

The manufacturer must prepare it with the battery saver feature to enhance its lifespan. So whenever you buy a product, make sure that there is a battery-saving feature that will help you to increase the battery life and preserve the energy. This will also make your equipment a cost-effective machine.

Technology

Technology is enhancing day-by-day because there are specific changes in the microprocessor of every piece of equipment. Whenever you buy any product, ensure that the equipment gives accurate results.

Furthermore, it should also follow new technology. This product uses conductivity measurements, which help this product to be more advanced technology. The meter must give the same range of chemicals and toxic metals in the water.

The Cost

This is the most critical factor because it highly influences a user’s decision. Whenever you buy a product, make sure you have a particular amount in mind to invest in buying the equipment.

If the product is pricey, that does not mean that it has very high quality. Be an informed consumer and ask the manufacturer every detail about the product before investing in a particular product.

Pre-Calibration

Whenever you buy equipment, ensure the TDS meter is calibrated to make its operation much more comfortable and easy. The calibration of equipment helps the user to get an accurate reading.

It also helps in reducing the hassle of the user in calibrating the TDS meter again and again. The calibration means the total dissolved solids level in the water is zero.

For example, the distilled water used in the laboratory does not have any chemicals or ions present in it, which is why its TDS meter value is 0 ppm.

Frequently Asked Questions

Does every TDS meter accurate? 

No, every TDS meter is not accurate. It does not happen for specific reasons, such as cost, technology, etc. Most equipment has maximum and minimum ranges, but they don’t tell you the exact amount. The products running through the electrical conductivity efficiently provide 100% accurate results.

What is TDS, and how is it different from PPM?

TDS  stands for total dissolved solids, meaning every chemical or any other contamination in the water. 
The PPM  stands for parts per million. The TDS meter always gives the reading in PPM of the total dissolved solvents in the water. For example, the result of the TDS meter is 20ppm.

Is it Okay to drink TDS water?

Yes, it’s okay to drink TDS water, but only if it lies in a particular range. The water should always be healthy and clean and have all the essential nutrients that help our body survive and grow. These essential nutrients contribute to the TDS value of the water.
According to the Environmental Protection Agency, around 500ppm of the TDS concentration can be considered the drinkable option,  but it shouldn’t be more than that. 
According to World Health Organisation, a TDS above 12000 mg per liter is not feasible to consume for human beings,  and the requirement is to be less than 300 mg per liter.

How will I know that my TDS meter is calibrated?

Whenever you buy equipment, make sure the TDS is calibrated. At this level, the water would not have any chemicals or any other contamination. Thus the value in the meter will be 0PPM, for example, distilled water.

Conclusion

TDS means the number of chemicals, organic or inorganic salts, and other contaminants in the water. The high range of TDS  in the water is not beneficial for humans and can result in several diseases.

To check the TDS level in the water bodies,  TDS meters are used by the people. It not only helps precisely measure the TDS content but also helps in providing an accurate value of the contaminants.

In this article, we have discussed some of the most affordable and accurate TDS meters present in the market. This article will help you to make a final decision about investing in the TDS meter. Ensure that you are replacing your TDS meter and periodically maintaining it for its accuracy.
