Water Quality Sensor Products

Description

There are two common types of water quality sensors: TDSTotal Dissolved Solids (TDS) is a measure of the amount of total combined organic and inorganic substances dissolved in water and can be expressed in milligrams per liter (mg/L) or parts per million (ppm). The TDS value is used to indicate water quality, where typically higher TDS values indicate poorer water quality. and Turbidity. A TDS sensor can be used to monitor water quality for aquariums, hydroponics, water purifiers, etc by determining the total amount of dissolved substances in the water. Turbidity is is a measure of the relative clarity of a liquid, where the cloudiness or haziness is caused by large numbers of individual particles that are generally invisible to the naked eye, such as sediment, soluble colored organic compounds, algae, and other microscopic organisms.

More details on water quality sensors can be found in the Water Monitoring System Components article.
