Water scarcity is rising daily and the source of water cannot be trusted. The TDS level of drinking water plays an important role in the health and wellness of your family. Water with an excessively high or low TDS level is not suited for drinking. But how would you know whether the drinking water is suitable? Well, the best tds meter in India can help you through the problems. It can help you live the safe, active, and prosperous life you deserve.

What Is a TDS Meter?

TDS refers to the Total Dissolved Solids and it is the combined organic and inorganic particles present in the water. It is inclusive of anything other than pure water molecules. Sometimes running tap water contains potential contaminants like trace materials, potassium, calcium, magnesium, and phosphates which are very unsafe for human consumption.

A TDS meter is used for determining the level of dissolved particles and measured in ppm or parts-per-million. But getting the right TDS reading of your groundwater or municipal water supply is not an easy task. In some cases, buying the right TDS meter for drinking is the most viable solution.

Why Do I Need a TDS Meter?

According to time the reports of the World Health Organization, TDS in drinking water refers to reliable information on the potential health impacts associated with the total dissolved solids. Since the level of these substances can be very erratic depending on the source of water supply, there is no health-based guideline for the ideal TDS level.
The Bureau of Indian Standards or BIS has set up an acceptable level of TDS in drinkable water. The most plausible level of TDS should be 500mg/L in drinking water. But the report also mentions that when there is no other source of drinking water available, the proportions of TDS can be relaxed up to 2000 mg/L. It also mentions when the amount of TDS in drinking water is more than 500mg/ L, the taste of the water is also affected in some cases, which may also lead to reduced palatability. Sometimes, such water also causes digestive issues, diarrhea, and gastrointestinal disorders.
So how would you know whether the drinking water available at your home is safe for drinking or not? The best way to ensure it is through a hand-held TDS meter. It’s worthy of mention here that a major part of the dissolved minerals present in water is very useful for our health. Therefore, there shouldn’t be any misconception that zero dissolvable TDS is a sign of appropriate drinking water. Moreover, reducing the TDS level to a meager level negatively impacts the pH level of water. Also, water will taste dull in such conditions. Even though there is no recommended lower limit, the TDS level of water should be at least 80ppm.

How to Choose the Best TDS Meter?

TDS meters are equipped with built-in automatic temperature compensation or ATC which helps in giving the most appropriate TDS measurement. With a huge number of the best TDS meter in india available online, how would you understand which option will serve your purpose the best? Here goes a useful guide that would help you lay your hands on the right device.


Typically, TDS meters takes three types of measurements and these are:

  • Electrical Conductivity: TDS meters also function as EC meters and it measures the level of electrical conductivity present in water so that TDS level can be detected. It is displayed in the form of uS or micro siemens or S i.e., siemens.
  • TDS: This is shown in the form of parts per million or PPM.
  • Temperature: Since all TDS meters come with a built-in temperature sensor, you can also know the temperature of the water along with TDS and EC.
Some premium TDS meters also show ph readings which are very useful for hydroponics and swimming pools.


Since TDS meters are quite small in size the display is invariably very small. But when you opt for a TDS meter, make sure that the display is large enough for the readings to be legible. It’s better to opt for TDS meters which are armed with a backlit display so that you can see the readings in all conditions.


The pricier the TDS meters, the better will be the accuracy. If you want maximum precision on the TDS level of water, make sure that you invest in a premium class device. A narrow error margin with a fine resolution of 0.1 ppm is the most suitable, particularly for low display.
It is worthy of note that the accuracy levels of TDS are dependent on how the reading is taken. You should closely follow the instructions for testing. For instance, if the manufacturers recommend you to test the TDS level with flowing water, you have to do it that way to ensure maximum accuracy.

Mode of Calibration

Another means of enhancing accuracy is to opt for TDS meters which can be calibrated. Although some of them come with a default calibration from the factory, they may become off-kilter after regular use. If the meters can be recalibrated, it would work fine.
Other functions to look for in a TDS meter are auto-off technology and hold function. With the auto-off technology, the display is switched off when the meter is left unused. This helps in saving battery life. On the other hand, the hold function freezes the readings so that you can see the display even when the meter is removed from the water.
