If you want to test water purity, here’s our list of the best TDS meters to help you choose the right one. TDS meters determine the presence of dissolved solids in the liquid. And, while this doesn’t give you an accurate reading of the number of dissolved solids, it measures the electrical conductivity, which is a clear indication of the particles present in the liquid. Moderate to high TDS level doesn’t just change the taste of water but also causes serious health hazards (1). Hence, research by the World Health Organisation says that less than 300 mg/liter is the appropriate level of TDS in water, which is preferably a healthier choice for human beings (2).

With various options available, choosing the right one can be challenging. So, explore our list of products and features to make an informed decision.

Now that you have been through our review of the 11 best TDS meters for drinking water, we will share a few tips on what to keep in mind while choosing a TDS meter for your use.

How To Choose The Right TDS Meter For Drinking Water

• Ratings or readings

It is another vital point that you need to check in every TDS meter, as it relates to the checking process of the water obtained from diverse sources. The common unit of TDS is milligrams per liter (mg/l), whereas some meters also show readings as parts per million (ppm) (3). Hence, the company must mention the micron ratings or PPM ratings in the product description. If not, there is no way of knowing the actual micron or PPM rating of the meter. A good quality TDS meter should have a micron rating of 0.3 microns, and for PPM readings, you should buy a meter that has 0 to at least 990 ppm.

• Purpose

While buying a TDS meter, you need to keep in mind whether you need it for single-purpose or multi-purpose use. A single-purpose meter can be used for a particular sample of water only, that is, you can use it for only filtered water. But if you buy a multi-purpose meter, you can check any type of water with it.

• 电池可取之处

The battery life of a TDS meter is generally limited. The more you use the product the faster the battery gets exhausted, and you may have to invest in a new TDS meter. To increase the longevity of the product, it’s wise to buy a product with battery-saving features that shut off automatically and preserve battery life.

• Technology

The microprocessor TDS meter uses the latest technology and gives accurate and reliable results. Most meters use electrical conductivity for measurements which is used to assess the presence of electrolytes. Advanced technologies employ several principles and conversions to ensure accurate readings. It is also of vital importance that the meter gives a reading of chemicals and toxic metals present in the water.

• Added features

Many TDS meter brands offer a range of additional features, like you can choose one offering you a leather cover for the meter to protect it. Also, some meters have the feature of taking the temperature of the water as well. But do keep in mind whether these additional features of the TDS meter are worthwhile for you as they would come at an extra cost.
