FAQS
While both TDS and EC relate to dissolved substances in water, they are not the same. EC measures the ability of water to conduct electricity, while TDS measures the total weight of dissolved solids. EC is often used to estimate TDS, but the conversion factor can vary depending on the composition of the water. A tds meter for drinking water provides a more direct measurement of TDS.
Calibration frequency depends on the meter's usage and the water quality being tested. Generally, it's recommended to calibrate a tds meter for drinking water at least once a month, or more frequently if it's used heavily or exposed to extreme conditions. Always use a calibration standard specifically designed for TDS meters.
The EPA recommends a maximum TDS level of 500 mg/L for drinking water. However, the WHO guidelines suggest levels below 300 mg/L are considered excellent.
