Greentest Water Tester for Drinking Water: A Solution to Drink Healthy

Pure drinking water is a requirement for a healthy body. Sometimes, people ignore the quality of drinking water while taking care of their health, but the fact is, the quality of drinking water can affect human bodies in several ways. There are several minerals and other elements that we consume through drinking water. An imbalance in those elements in the body can cause severe health-related issues. So, how to measure the purity of drinking water? Greentest has come up with an advanced technology to offer an ideal solution to this problem. Greentest offers a high-quality TDS meter for drinking water testing purposes that can help users to understand whether the water they are drinking is safe enough or not.

What is a water testing TDS meter?

To understand what a water testing TDS meter is, it is important to understand what TDS stands for and how it can affect our bodies. TDS stands for Total Dissolved Solids. This unit reflects the total concentration of dissolved substances in water, including both potentially harmful substances and beneficial minerals. An increased level of TDS indicates that a high amount of solid substances are dissolved in the water, and most of them are potentially harmful to human bodies. In other words, this unit reflects the hardness of water. The hardness of water usually depends on the amount of calcium and magnesium dissolved in that water. Besides these two substances, there can be several other substances that are harmful to human health. Greentest's TDS meter for drinking water allows users to test the hardness with the level of TDS of the water so that users can understand whether the water is safe and healthy for them or not. 

Why do you need a water tester for drinking water?

Water is the primary element of our bodies that keeps us going. There are plenty of minerals and other substances that we consume through water. These minerals and substances also contribute to the proportion of elements in our bodies. An imbalance of this equation can cause severe health-related issues like kidney disease, metabolism-related issues, heart issues, bone problems, and so on. While talking about living a healthy lifestyle, usually people mention food intake and other factors, but unfortunately, most people forget about the water they drink every day. Water is one of the main sources of minerals and other substances in our bodies.  With a water tester for drinking water, people can also take care of the purity of water they are drinking. You need a water tester for drinking water to take care of your health. 

What is the ideal level of TDS in water and what happens when the level exceeds it?

When you use a water tester for drinking water to test the purity of the water you are drinking, you should also know what the ideal level is. According to recent studies and reports, the ideal TDS level in drinking water is anything between 300 ppm-500 ppm (50-150 tds). When the level exceeds, with every increased ppm, the water becomes more and more unsafe for drinking purposes. If the TDS level in water is something between 1000 ppm-2000 ppm, it means that the water is not safe enough to drink. On the other hand, if the TDS level is less than 50, it also makes the water unsafe to drink as, at this point, the water doesn't have any essential minerals or substances that are necessary for human growth. With a TDS meter for drinking water, you can measure the TDS level on your own. 

You should test the purity of water by using a water testing TDS meter for drinking water to avoid the effects of consuming unhealthy drinking water. A high level of TDS in drinking water can cause several health issues, such as nausea, diarrhea, dizziness, lung irritation, rashes, and skin itchiness. If you continue consuming water with a high TDS, it can permanently damage your kidneys and cause kidney-related issues such as kidney stones, kidney failure, etc. Also, drinking water with high TDS for a long time will expose your body and internal organs of your body to unhealthy substances and chemicals. These toxins can lead to severe health-related issues such as cancer. With the Greentest TDS meter for drinking water, you can check the purity level of water before drinking it. 

How to use the Greentest water testing TDS meter?

Greentest offers an evolutionary device which is a TDS meter for drinking water which allows users to know the TDS levels of the water before drinking so that people can also take care of their water consumption. Besides eating healthy, the developers of this device understand drinking healthy is also important. As this water tester for drinking water is developed to help people to check the purity of drinking water on the spot before drinking it, developers made sure to eliminate all the complications from the user interface of this device. This device is extremely easy to use without any hazards, and anyone can use that. Here is how one can use the water tester for drinking water offered by Greentest.

1.First, the user needs to turn on the tester to test the water by using this water testing TDS meter. 

2.There, users will be provided with a catalog of options from which they need to choose water.

3.Now, the user needs to dip the tip of the probe into the water that needs to be tested. 

4.Wait for a few seconds ( 3 seconds) so that the water tester for drinking water can show you the result.

5.Make sure to clean the probe once you are done

Note- Users can also taste the purity of fruits, vegetables, and other food items by using the same process. 

What method does this water testing TDS meter follow to test the purity of water?

To test the purity of water, this specially designed advanced water tester for drinking water follows a catalog that is incorporated into the device. The developers have tailored the catalog depending on more than 1000 reports and studies where the most advanced technology and science are used. After doing thorough research on the ideal levels of several compounds in the water and food items, the data catalog was created and incorporated within that device. Similarly, while incorporating the feature of TDS meter for drinking water into this advanced device, the developers did their research and set an ideal bar for TDS levels in the water, followed by setting them in the system of the water tester for drinking water. 

The basic standard for TDS level in water or the water hardness level is anything between 300 PPM to 500 PPM. According to the World Health Organisation (WHO) as well, water that falls into the parameters is safe for drinking. Any water with TDS levels of more than 1000 ppm is not safe enough for drinking purposes. The same parameters are followed by Greentest while developing its water-testing TDS meter. 

Whenever the user dips the tip of the probe into the water, it instantly measures the level of TDS in that water, followed by comparing that with the data incorporated into the device. When the device finds out that the TDS level of the water into which the probe tip is dipped is not ideal, the TDS meter for drinking water immediately alerts the consumer. 

What are the functions of the Greentest water tester for drinking water?

Greentest's water testing TDS meter allows consumers to check the purity of the water before drinking it so that they can take care of their health in a better way. Besides allowing users to check the purity of the drinking water, the water testing TDS meter also allows users to check the nitrate levels in all the common food items to ensure the purity, including fruits, vegetables, fish, meat items, and seafood. The super thin probes of the device don't even leave any mark on the food items to maintain their purity. 

This TDS meter for drinking water allows users to check the purity of water as well as food items within 3 seconds. It offers quick and accurate results to consumers for complete satisfaction. The best part is the compact design of this device which allows users to take it anywhere. This USB rechargeable device has a battery life of 720mAh that can offer up to 20 hours of use time. So, it is also a perfect option if you are traveling somewhere and don't want to compromise your health. 

In conclusion, it can be said that the Greentest water testing TDS meter is one of the best devices you can get to take care of your health and avoid consuming harmful substances through water or food items. This TDS meter for drinking water is a must-have product for people who love themselves.
