TDS Meters (Total Dissolved Solids)
Total Dissolved Solids (TDS) is a measure of the solid matter dissolved in water. It is described as the sum of anions and cations present in water. Although TDS is not harmful to humans, their high levels may have a direct impact on the equipment and may also affect the water filtration process. This is why TDS is generally measured before installing any filtration equipment. TDS in water is measured using various types of TDS conductivity meters and chemical testing kits. Cannon Water Technology, Inc. provides one of the comprehensive categories of TDS measurement devices from industry-leading brands such as Myron L, Advantage Controls, and HM Digital. All the products displayed on this page can be shipped immediately.
What is TDS?
The dissolved solids constituents are mainly distinguished as cations and anions. It comprises both organic and inorganic constituents. Of these, cations are positively charged ions and anions are negatively charged ions. Dissolved solids may comprise the following types of anions and cations:
- Magnesium
- Calcium
- Sodium
- Potassium
- Sulfates
- Bicarbonates
- Chlorides
How is TDS Measured?
TDS is measured using any of the following methods:
- Conductivity: As indicated before, most organic and inorganic constituents in water are identified as cations or anions. These positive or negatively charged ions enable water to conduct electric currents. The conductivity of water may increase or decrease based on the amount of dissolved solids. These conductivity tests are performed using TDS conductivity testers. These TDS water tester always measure the conductivity of water and multiply it with a conversion factor.
- Gravimetric Analysis: This type of measurement is performed in laboratory settings. In this method, the water is evaporated and the remaining residual mass is dried on any type of evaporating dish. This dried mass is then measured through a weighing and filtering process.
At Cannon Water Technology, we provide only conductivity measurement solutions for TDS measurement. All TDS water tester determine the level of TDS by a unit of parts per million (ppm).
How Are TDS Results Interpreted?
TDS levels are differentiated as high or low on the basis of levels of TDS.
- Low TDS: If the water sample features TDS less than 100 ppm, it symbolizes low TDS content. The range between 150 and 250 ppm is considered excellent for health.
- High TDS: If a water sample shows TDS above 100 ppm then it is high TDS. EPA has fixed the TDS concentration at 500 ppm for drinking water. The water that has TDS above 1000 ppm is not recommended for consumption.
What is a TDS Meter and How Does it Work?
TDS meters are digital devices designed to measure TDS levels in water. Now coming to the next part how a TDS meter works? It mainly measures the electrical conductivity of water – the number of anions and cations. The electrical conductivity is zero, and anything above zero indicates the presence of TDS in water. TDS measurement device usually consider conversion factors ranging from 0.4 to 1.0. These factors are used to convert the measured EC into the estimated level of TDS. As a rule of thumb, high EC indicates a high conversion factor.
