Description

TDS stands for Total Dissolved Solids. A TDS sensor, is a device used to measure the concentration of dissolved solids in a liquid. These dissolved solids can include various inorganic salts, minerals, metals, and some organic compounds that are present in the water or solution.

TDS sensors work on the principle of electrical conductivity. When dissolved solids are present in a liquid, they can conduct electricity. The TDS sensor measures the electrical conductivity of the liquid and converts it into a TDS reading, typically expressed in parts per million (ppm) or milligrams per liter (mg/L).

TDS meters are commonly used in various applications, such as:

• Water quality testing: TDS meters are frequently used to check the purity of drinking water, aquarium water, swimming pool water, and water used in industrial processes.
• Hydroponics and aquaponics: TDS meters help monitor nutrient levels in hydroponic and aquaponic systems, ensuring that the plants receive the appropriate nutrient concentrations.
• Water treatment: TDS measurements assist in assessing the effectiveness of water treatment processes, such as reverse osmosis, to remove dissolved impurities.
• Beverage and food industry: TDS meters are used to monitor the quality and consistency of beverages and food products.

It's important to note that a TDS meter measures the total concentration of dissolved solids, but it does not identify the specific types of dissolved substances present. For that, additional testing and analysis may be required.

There are various organizations and guidelines that set standards and acceptable limits for TDS in different applications. Some common standards and guidelines include:

• Aquarium Water: The acceptable TDS range for aquarium water can vary depending on the type of fish and plants in the aquarium. However, a common range is between 150 to 800 ppm.
• Hydroponics: The optimal TDS range for hydroponic nutrient solutions depends on the specific plants being grown, but it generally falls within 800 to 1500 ppm.
• Swimming Pools: The recommended TDS range for swimming pool water is typically between 1000 to 1500 ppm.
• Industrial Processes: TDS requirements in industrial processes can vary widely depending on the specific application. The required TDS level may be determined by the process and the materials involved.

It's essential to check the specific standards and guidelines relevant to your particular application to ensure that the TDS levels are within the acceptable range for that specific use. Additionally, note that TDS is just one aspect of water quality, and other factors like pH, specific ions, and contaminants should also be considered for a comprehensive assessment.

*Note #1: TDS sensor can't use under the water above 55°C.
*Note #2: TDS sensor can't too close to the edge of the container, otherwise reading will be affected.
