TDS Meter- How Does It Work?

A TDS meter is a small device used to measure the level of total dissolved solids in drinking water. More specifically, these devices measure the conductivity of water, which is determined by the level of ionized solids such as salts and minerals in the solution. High TDS readings indicate that the water in your area is hard and potentially harmful for health.  

How to Use a TDS Meter?

TDS meters are usually very easy to use. All you have to do is remove the cover from the tip of the meter and submerge it one inch into a glass of water you want to test. Do not submerge the entire device into water, as this will cause irreparable damage.

Once the testing is complete, the meter is going to display the number of TDS in parts per million or PPM for short. Once finished, turn the device off and dry any water residue. 

When do you Need it?

In case you noticed that the tap water in your home has a weird taste or color, you will need a TDS meter to determine whether that water is safe to drink or not. Measuring TDS will also help you determine whether you need to set up a water filtration system to ensure you are consuming healthy water.

What are the Acceptable Levels of TDS in Drinking Water

The acceptable range of TDS in drinking water coming from a home tap is upto 500ppm, as stated by the Bureau of Indian Standards or BIS.

The World Health Organization, on the other hand, recommends that the TDS range as follows:  Less than 300mg/l excellent, in between 300-600mg/l as good, 600-900 as fair, 900-1200 as poor and beyond 1200 is unacceptable.

A TDS meter will help you determine which category your drinking water falls into. However, keep in mind that TDS levels over 1200ppm are less acceptable and that such water should not be consumed. 

How to Take Care of the TDS Meter

TDS meters are usually resistant to harmful chemicals that can be found in water and similar solutions. However, that does not mean you should completely neglect the maintenance of the device.

In fact, there are a few things you should remember to make sure your TDS reader lasts longer and gives out correct readings

For starters, make sure to dry the device completely after each use using a dry towel or a cloth.

Once completely dry, put the cap back on the measuring tip to avoid moisture and damage. Repeat this process each time you finish using the meter to avoid malfunction and inaccurate results

Three important Precautions you should know while using a TDS meter

Never try to dip the TDS meter into the solution more than recommended levels, you can get accurate readings by just dipping 1-2 inches of solution or the recommend level suggested by the product.

Avoid dipping the TDS meter in High temperature solutions as it will cause damage to the probe and may lead to irreparable damage

Do not expose the TDS meter to High temperatures or direct sun light and finally do not try to open the housing or repair the electronics of the product by yourself as it may result in malfunctioning.

Points to Consider Before Buying a TDS Meter

Here are some of the most important points to keep in mind when buying a TDS meter:


Most high quality TDS meters are extremely accurate when it comes to reading the total dissolved solids levels in water. However, if you want more specific accuracy in terms of other measurements and water temperature, you will have to look for a more advanced TDS meter. 

TDS Range 

TDS range is often used to determine the accuracy of a TDS measuring device. The average accuracy statement for most TDS meters is ± 2% f.s., with a range of 999 ppm TDS. All TDS measurements with this range are said to be highly accurate and efficient when testing drinking water.


Forgetting to turn the device off after use can lead to damage and unwanted consequences. However, if you choose the best TDS meter with an automatic shut off function, you won’t have to worry about this. Thanks to this feature, the device will shut off automatically a few minutes after use. 

Temperature Measurement

Advanced TDS meters offer extra features such as a temperature measurement function, which allows you to measure the temperature of water. Even though this metric is not as important as TDS level when it comes to determining the quality of water, it is good to know the temperature while you are at it.

Digital Display

Look for TDS meters with high quality digital displays to make sure the readings are easily accessible. The last thing you want is a meter with a small and confusing display that makes measurements too difficult to see. Digital displays are the best solution as they are most responsive and also very easy to read at a single glance. 

Build Quality

Naturally, you want to choose a TDS meter with a good build quality. In other words, the device should be made of high quality materials and components to ensure a long lifespan and accurate readings. Stay away from cheaply built plastic readers and stick to the best TDS meters in India, which you can find on our list of reviews above. 

Pre-calibrated and Easy to Use

The best and easiest TDS meters to use are the pre-calibrated ones. These readers ensure higher accuracy with lesser chance of malfunction, as they come pre-calibrated since day one. Naturally, you might have to calibrate the meter again from time to time.


Measuring the level of total dissolved solids in water will let you know whether the water you are drinking fits the recommended standards. The total number of TDS in water should be with in the limits as set by the WHO or fit the National Standards, whereas the best recommended reading results are usually below 300ppm.

If your meter shows more than the recommended TDS limit in your water, consider switching to bottled water or installing a water water purifier system in your home. Either way, our guide and list of reviews will help you find the best TDS meter in India to ensure you are drinking clean and healthy water. We have included some of the best TDS brands in India so you can find one for home use with an acceptable price.
