What is a TDS meter?

TDS meter for drinking water

A TDS water meter is a tool that indicates the amount of total dissolved solids (TDS) in the water. The hand-held product measures electrical conductivity (EC). EC concentration increases by the presence of ionized solids like salts and minerals.

It does not detect dissolved organic solids as they do not affect the conductivity of the solvent.

Here are some critical notes regarding TDS sensor:

      • The readings are expressed in terms of PPM or parts per million.
      • It can be used to find out the TDS of your household reverse osmosis purifying system.
      • Additionally, it can also be used to assess the quality of water in the aquarium or swimming pools.

The tool looks like a thermometer and has a digital screen to express the reading. They typically come with a hold-function, which helps you stabilize and save the levels. Moreover, the power on and off features help you conserve energy to extend battery life.

The water quality tester can come in pretty handy to find out about the performance of your RO water purifier. It can also identify if the filters are working efficiently or require any replacements.

A TDS tester is readily available in markets and is affordable too! Buying it could also help to extend your filter and purifier life.

Buying Guide

how to buy a water TDS meter

Here are some notable factors to consider when purchasing a digital TDS meter.

Battery saving feature

Batteries play an essential role in the life of this tool. Extensively running the product will exhaust its battery life. It means that you will need to buy another meter shortly after your use.

However, to increase the longevity of the product, the meters come with battery-saving features. By shutting off automatically, they preserve energy, increasing battery life. That makes TDS checking machines cost-effective too!

Technology

The recent advancement in their technology is the microprocessor one. It ensures that the user gets accurate and reliable results.

Most meters use the electrical conductivity measurements, which assesses the presence of electrolytes. For this reason, it becomes crucial to opt for advanced technologies. They employ several principles and conversions to ensure accuracy.

 It is also vital so that the meter gives a measure of toxic metals and chemicals present in the water.

Cost

Another major determinant to look at is the price tag. A higher price tag does not necessarily mean high-quality. In fact, the majority of the medium-priced products work just as well as the high-end ones.

Take the budget into consideration when checking out the TDS water meter.

FAQs

If you still have questions regarding their importance and performance, take a look at these FAQs.

Are TDS meters accurate?

Accuracy becomes especially crucial with a tool like this one. In terms of conductivity, readings as low as zero are preferred. Most devices contain minimum and maximum ranges as an expression of TDS detection.

Since they measure electrical conductivity, the results are never 100% accurate. However, they are pretty close to the actual measure.

How accurate are TDS meters?

A typical TDS meter is accurate to plus/minus 2 per cent. With a ppm of 1000, you can find out the accuracy by multiplying 1000 with 0.2. It means the results are typically different from +/- 20 ppm.

What does a TDS meter tell you?

The typical TDS meters are similar to most thermometers. They are hand-held and easy-to-use. You can insert their tips in filtered water or in pools to find out the concentration of salts and other solids.

However, it is essential to note that a TDS meter doesn’t measure the level of solids, but in fact, the electrical conductivity (EC). It is a measure of the positively and negatively charged ions.

Pure water has an electrical conductivity of zero. If there is a measure of above zero, it indicates the existence of salts and solids in the water.

The meter then converts this EC to TDS and also measures the temperature.

What is the difference between TDS and PPM?

PPM is a measure of TDS and stands for parts per million. It means, your meter will mostly offer you a reading of, for example, 200 ppm of total dissolved solids.

What is TDS 3 meter?

TDS-3 is a digital TDS meter useful got almost any application. It estimates the quality of water in your purifier, spa, pool, or anywhere. You can even use it for industrial wastewater treatment.

The HM TDS-3 is a commonly used TDS sensor. It is portable and highly reliable, making it ideal for both domestic and commercial use. It is based on conductivity and expresses the readings in ppm.

Both TDS-3 and TDS-4 measure the same range: 0-9990 ppm. However, TDS-3 is more for commercial use, when compared to the lightweight and small-sized TDS-4.

How much TDS water is good for health?

According to the Environmental Protection Agency (EPA), the permissible levels of TDS concentration are 500 ppm.

The World Health Organization (WHO) considers a TDS of above 1200 mg/litre as undrinkable. The recommended TDS levels are 300 mg/litre. Therefore, it is essential to check the concentration of your water before consumption.

Conclusion

TDS testers are handy in checking if your purifier is working to its best ability. It also ensures the water you’re consuming is healthy or not. Considering its efficiency and user-friendly features, anyone can use it.

While they don’t precisely measure TDS, the electrical conductivity measure is also a reliable way. You can find out the quality of water in the aquarium or swimming pool and also of the reverse osmosis system at home.

The tool can help increase the lifespan of your purifiers. With a TDS water meter at hand, you will be able to estimate changes and replacements timely.
