Top 5 Best TDS Meters in India 2019 – Reviews & Buying Guide

 TDS is the short form of Total Dissolved Solids. It refers to the total dissolved solids in a liquid including water in a suspended, micro-granular, ionized and molecular form which could be beneficial in many ways. The water is assessed for the total dissolved solids not to consider the water as unsafe because of the presence of the total dissolved solids.

Instead, it is meant to determine whether there is a need for further treatment depending on the purpose for which the water is supposed to be used.

The TDS meter is the device that is put to use

  • During the commercial filtration system to determine the efficiency of the system.
  • In Hydroponic systems to check the salt levels in water
  • To test if there is any contamination in the home purifying system.
  • To test the membrane of the home reverse osmosis system.

In short, you can consider the TDS meter as a device that can be used to identify all the salts, metals, minerals, compounds, etc that is present in the water that is used for testing. There is a need to use TDS meters as the presence of these salts, metals and other compounds are actually considered to be contaminants which can make the water unfit for drinking until it is treated properly. The water purification systems are meant to treat water and the TDS meter would tell you how efficiently the purification system is working. Since most of the dissolved molecules in water the TDS concentration can be obtained in the form of the total amount of positively-charged ions(cations) and negatively charged ions (anions) in the water.

How does TDS mix up with water?

 There is no doubt that there is some amount of dissolved salts in all forms of water whether it is from a natural source, industrial wastewater or water run-off. Even natural water consists of dissolved salts because of minerals, salt, and metals in the soil like sodium, potassium, and iron mix with the water.  You then have the chemicals that are used to treat water as well as the piping and other hardware fittings which contribute some amount of dissolved salts the other sources of TDS includes mineral springs, de-icing of snow, carbonate deposits as well as agricultural wastes are all sources of TDS. Water would also contain bacteria, viruses, phytoplankton, organic compounds, salts, heavy metals, pharmaceutical chemicals deposited in water all of which add up to the TDS in water.

Acceptable level of TDS

 The acceptable level of TDS  concentration in water that is supposed to be used for consumption by human beings is 500 parts per million or milligrams per unit of water. It is expressed as 500ppm or mg/l. If the TDS level is greater than 1000ppm it is considered unsafe for consumption.

How does the TDS meter work?

 The TDS meter that looks like a thermometer is placed in the water to be tested. Immediately the measurement sensors in the TDS meter start working and you will receive a notification within 10 seconds which will indicate the mineral content in the water. This will help determine the efficiency of the purification system that is in place for water and also determine what further treatment is required to reduce the concentration of minerals.

Buying Guide for TDS Meters

  When you are about to buy a TDS meter, it is important to consider certain important points. This would ensure that the results are accurate and you are also able to get all the information that is necessary to consider if the water needs further treatment or not. The important features include

Fit for purpose for which it is about to be used – TDS meter you choose should be easy to handle and suitable for the purpose for which you are using it.  TDS meters for domestic use is different from those that are used for large scale testing. Therefore, determining the purpose for which it is going to be used would be helpful in choosing the right TDS Meter.

 Technology – Though the TDS meter is used to measure the TDS in water, there are a number of advanced technical principles that are applied to get the reading. Though calcium and sodium are dissolved salts they cannot be considered as contaminants. Therefore, the TDS meter with advanced technological features would be able to give you a fair reading of each type of salts that are present in the water. The quality of the microsensors and the microprocessors are very important to get the right readings. Similarly, the technology employed should be advanced enough to ensure that the TDS meter gives a fair reading of the noxious metals and pollutants that are present in the water that is tested.

Pre calibrated – The precalibrated TDS meters are easy to use and you can expect accurate readings when compared to the TDS meters that come without the calibrations. A wide range of calibrations starting from 0 and going on up to 999ppm is also an added advantage to have in a TDS meter.

 Battery – The batteries that are used in the TDS meter would also play a vital role in ensuring speedy results. the longevity of the battery also has to be considered because this would prevent you from having to buy a TDS meter again within a short period of use.in other words, battery life is indeed one factor that would make the purchase of TDS meter a cost-effective one.

Reputation – it is indeed important to research and find a reputed brand for TDS meters. You can use the net, go through the reviews and even use word of mouth communication to choose the same. However, the brand you choose must be one that is known for gadgets that have provided accurate results consistently.
