How To Check Water TDS Level At Home In India?

A number of methods are available for checking water tds level at home in India. You just have to find out which works best for you. Below we have compiled a list of the most popular methods, with a brief description of each.

But Let’s first understand what is TDS level in water and why you need to check it?

What is TDS in Water & Why Should You Measure It?

The term TDS refers to the total dissolved solids in a liquid and refers to the sum of all organic and inorganic substances that are present in the liquid. This level is expressed in parts per million (ppm), or in milligrams per liter (mg/L). The three most common inorganic substances present in water are magnesium, calcium, and potassium. It is actually beneficial to have these minerals present in the water to a certain extent. However, when the level of the minerals becomes too high, it can cause problems.

The presence of Total Dissolved Solids (TDS) in water is one of the main factors that determine its suitability for different purposes. Having high levels of TDS can cause health problems as well as affect the taste and appearance of water. Thus, it is important that you check the TDS level in water before you use it for drinking, cooking, or any other purpose. The TDS level in water can be used as a good indicator of whether or not the water you’re drinking is pure or impure, depending on how the TDS level is measured.

Major Substance Causing High TDS Level In Water:


What is the Ideal TDS Level of Drinking Water?

According to Bureau Of Indian Standards, the maximum total dissolved solids (TDS) in drinking water is 500 mg/L. The WHO, on the other hand, recommends that water with a TDS level of less than 300 mg/litre be considered safe for human consumption.

No matter what type of water you use, whether it is from a nearby lake or a storage tank, it must meet the standards described above. If the level is higher than 500 mg per liter, then we strongly advise you to avoid taking it.

Ideally, the level of TDS should be below 350 ppm (parts per million) in drinking water. If these levels are higher than recommended, they may cause adverse health effects, including nausea, vomiting, and diarrhea. Additionally, having an excessive level of TDS in drinking water can lead to scaling or crusting inside pipes and appliances, which can reduce the effectiveness of water treatment chemicals.

TDS Level Chart for Drinking Water:

TDS in Water (measured in PPM)Suitability for Drinking Water
Between 50-150Excellent for drinking
300-500Poor, not good for drinking
Above 1200Unacceptable

What should you do if the TDS in your drinking water exceeds 300 mg/L?

If your TDS is higher than 300 mg L you can use a RO water purifier, but if TDS is less than 300 mg L you do not need to purchase a RO water purifier; following running the outer and inner filters only, you will filter out most organic and inorganic impurities that are easily removed by an UF filter and kill bacteria that you can sanitize with a UV chamber, so using UF UV in conjunction with the RO purification is the best method of getting your TDS to be around 300 mg L.

3 Easy Methods Which You Can Use For Checking TDS Level at Home

Method 1: How To Check Water TDS Level Using Digital TDS Meter?

If you are looking for an inexpensive and simple way to measure the total dissolved solids (TDS) in your water, a digital TDS meter could be a great option. TDS meters are small, handheld devices that use sensors to detect the electrical conductivity of a liquid using a sensor. As a result, they are able to calculate the TDS levels in water accurately.

The market is full of various digital TDS meters, so it is essential that you do your research before making a purchase. Make sure you buy a meter that has an easy-to-read screen that can be seen in low light conditions and that has a backlight. Additionally, it is imperative to seek out a TDS meter that is as accurate as possible within an error of +/- 2% of the actual level.

Steps to measure TDS level in water using digital TDS meter:

  • Take off the protective cap.
  • Now turn the TDS meter on. On the back of the TDS meter, you will find an ON/OFF switch that you can turn on and off.
  • Put the meter into the water until it has submerged up to the maximum immersion level (2 inches).
  • Stir the meter gently to dislodge any air bubbles that may be present.
  • During this time, you should wait for the reading to stabilize (approximatively 10 seconds).
  • Take it out of the water and press the HOLD button until you see the reading.
  • By the way, if the meter displays the symbol ‘x10’, it means that you have to multiply the reading by ten before you proceed.
  • Immediately after you have used your meter, you will need to shake off the excess water from the meter and replace the cap.

The following precautions should be kept in mind while using a digital TDS meter:

  1. In order to ensure that the meter is watertight, it should not be dipped more than 2 inches below the waterline.
  2. The meter should not be stored in areas subject to high temperatures or those exposed to direct sunlight.

Method 2: How To Check TDS Using Filter Paper & A Scale?

You can easily determine your water’s TDS level even if you do not have a digital TDS meter. If you already have filter paper and a scale around the house, it might be a good idea to use them together to make the process easier. 

To measure the TDS level in drinking water, a filter paper is used to filter out any solid particles in the water. The water is then poured onto the scale to measure the weight of the water sample. The TDS level is then calculated by dividing the weight of the water sample by the volume of the water sample.

To check TDS level, Use this formula:

TDS = [(B-A) X 1000]/ml sample
(B = weight of the evaporating dish with the particles in it.
A= the weight of the evaporating dish alone.
ml = 50 as we have taken 50ml of water
Resulted TDS value will be in mg/L)

Method 3: How To Check Water TDS Using Electrical Conductivity

When testing water for TDS levels, a conductivity metre can be used to obtain an approximate reading. This is because water with a higher TDS content has a higher electrical conductivity. By connecting your metre and conducting a test, you can determine the range within which your water falls and make any necessary adjustments. Bear in mind that, while this is an accurate indicator of TDS levels, it is not an exact measurement.

Frequently asked questions about Water TDS Level:

  • What to do if the TDS level is high?

    It is crucial to take the necessary measures in order to reduce TDS in water in case they are present in large amounts. If TDS levels in water are high, this can cause health problems if not reduced.

    There are a number of ways to remove TDS from water, one of which is by using a water purifier that has been designed specifically to do so. Additionally, you can make other efforts to lower the amount of TDS in your home, such as ensuring that your house is well-insulated and using a humidifier to keep your home’s air moist.

  • Does a high TDS level always mean the water is unfit for consumption?

    A high TDS level does not always mean that the water is unfit for consumption. The TDS level is a measure of the dissolved solids in the water, and can be affected by a variety of factors, including the source of the water and the treatment process. High levels of TDS can affect the taste and quality of the water, but typically do not pose a health risk.

  • What to do if the TDS level is low?

    A low level of TDS in your water could indicate that your water is not being disinfected properly or that there is a problem with your water treatment system. In order to identify the cause and to obtain help to fix the problem, you need to contact your local water authority.

  • How to reduce the TDS level in drinking water?

    There are several ways to reduce the TDS level in drinking water. One way is to install a reverse osmosis system in your home. This system uses a special filter that removes most of the dissolved solids from the water. Another way to reduce the TDS level is to use a distiller. This device boils the water and then condenses the steam, which removes the dissolved solids. You can also add a water softener to your home’s water supply.

  • Can boiling water reduce TDS?

    Yes, boiling water can reduce TDS levels. This is because boiling water causes the water to evaporate, which removes some of the dissolved solids. However, it is important to note that boiling water will not remove all of the dissolved solids, so it is still important to use filtered water or water with low TDS levels.

  • What Is the Difference Between TDS And Hardness?

    The difference between TDS and hardness is that TDS measures the dissolved solids in water while hardness measures the calcium and magnesium levels. Hardness can cause scale build-up on faucets and pipes, while TDS can affect the taste and odor of water.
