Checking the TDS of your drinking water and tap water is very necessary these days due to the polluted environment. The TDS stands for Total Dissolved Solids which are the inorganic salts and organic matter in a liquid. This includes calcium, magnesium, sodium, lead, nitrate, cadmium, copper, etc. When water passes through stones, pipes, or any kind of surface, these particles are absorbed into the water. Some toxic ions and substances such as lead, nitrate, cadmium, or copper can lead to health hazards.
Testing the TDS of water is a great way to check the quality of water that you receive for household and drinking purposes. Water with TDS below 100mg/L and above 50mg/L is completely safe to drink. Water with a TDS level of more than 1000mg/L is unfit for consumption.
To check the Total Dissolved Solids (TDS) of water you need a TDS meter. It is a digital device that looks just like a digital thermometer and has a digital screen to express the reading. The TDS meter is necessary for checking the purity of water. There are a lot of TDS meters that are available online and many of them are fake. Therefore, Here we curated the list of best TDS meters for water testing at home.

Things to check in a TDS Meter
Accuracy and Precision:
Look for a TDS meter with high accuracy and precision. The measurement accuracy is usually specified in parts per million (ppm) or milligrams per liter (mg/L). The lower the margin of error, the better.
Measurement Range:
Ensure the TDS meter’s measurement range meets your requirements. Some meters have a wide range, which is useful for various applications, while others are more specialized for specific tasks.
Calibration:
Check if the TDS meter is easy to calibrate. Many models allow you to calibrate them using standard calibration solutions, ensuring accurate readings over time.
Display:
Consider the display type and size. A clear and easy-to-read LCD display with backlighting can be very helpful, especially in low-light conditions.
Automatic Temperature Compensation (ATC):
ATC is crucial for accurate TDS measurements, as the conductivity of water can change with temperature. A meter with ATC adjusts the readings according to the water’s temperature.
Build Quality and Durability:
Look for a TDS meter with a sturdy build and a protective casing. This ensures the meter can withstand regular use and potential accidents.
Price:
TDS meters are available in a wide price range. While it’s tempting to opt for a cheaper model, investing in a higher-quality meter with better accuracy and durability may be a wise decision in the long run.
Warranty and Customer Support:
Check if the TDS meter comes with a warranty and if the manufacturer provides responsive customer support in case you encounter any issues.
Additional Features:
Some TDS meters come with additional features such as data storage, data logging, or the ability to switch between TDS and conductivity measurements. Consider whether these features are important for your specific needs.
Certifications:
If you need to comply with specific regulations or standards, ensure that the TDS meter meets the necessary certifications for your industry or application.
Accessories:
Check if the TDS meter comes with essential accessories like calibration solutions, carrying cases, or protective caps.
By carefully considering these factors, you can make an informed decision when purchasing a TDS meter that suits your specific requirements and ensures accurate and reliable measurements of total dissolved solids in your water or liquid samples.
