The TDS meter is a versatile instrument suitable for a wide range of applications, encompassing water purification, hydroponics, aquarium maintenance, and industrial wastewater treatment.
Measurement of Total Dissolved Solids (TDS)
Total Dissolved Solids (TDS) represent the cumulative concentration of mineral salts or metals dissolved in a given water sample, typically expressed in milligrams per litre, also known as parts per million (1 ppm = 1 mg/Liter).
The purity of water and the efficacy of water sources, purification systems, and biofilters are determined by the TDS readings. Water quality profoundly impacts all entities reliant on it.

TDS plays a pivotal role in various water-related parameters essential for aquaponics, swimming pools, and other applications. Some aquatic species are exceedingly sensitive to the TDS levels in their environment. TDS exhibits a close relationship with the Oxidation Reduction Potential (ORP) levels in water; when ORP values are high, TDS levels tend to be low, and vice versa.
The Significance of Regular TDS Monitoring
It is crucial to regularly measure and monitor the TDS levels in aquatic environments for several reasons:
(a) To assess the condition of water sources, filters, and pipelines.
(b) To ensure that mineral levels are consistently within the appropriate range, which is vital for marine and aquatic life.
(c) To maintain optimal water parameters in swimming pools, fishponds, and similar settings, with immediate corrective action taken in response to any deviations.
Recommended TDS Levels
For drinking water, the ideal TDS range is typically between 300 to 500 PPM (Parts Per Million). Water with TDS levels below 80 PPM is not advisable for consumption.
High TDS Levels and Associated Risks
Elevated TDS levels often signal potential concerns and warrant meticulous attention. Common salts like potassium, chlorides, and sodium are frequently responsible for high TDS levels. These ions generally have minimal immediate impacts on pond ecology. However, toxic ions such as mercury and lead may also dissolve in water, posing severe consequences.
Therefore, it is advisable to periodically send water samples for comprehensive analysis or when deemed necessary.
Calibration of TDS Meters
Regular calibration of TDS meters is equally crucial, as a calibrated meter provides more accurate readings and prolongs the equipment’s lifespan. It is recommended to calibrate your equipment every three months or after conducting 10 to 20 tests.
