FAQ

Q1: What are the main applications of industrial salinity sensors? ❯

Industrial salinity sensors are suitable for applications requiring long-term monitoring of water salinity, such as industrial wastewater treatment, chemical process control, aquaculture, water treatment facilities, laboratory analysis, and drinking water and circulating water systems.

Q2: What is the working principle of a salinity sensor? ❯

Industrial salinity sensors are typically based on the principle of conductivity measurement, calculating salinity by detecting the conductivity of water. Because dissolved salts increase the conductivity of water, the sensor can calculate the corresponding salinity value based on the change in conductivity.

Q3: Do salinity sensors require regular maintenance? ❯

To ensure measurement accuracy, it is recommended to clean the electrode surface regularly to prevent dirt, algae, or sediment from affecting the measurement. If the operating environment is complex, the maintenance frequency may be increased appropriately.

industrial salinity sensor solid for water quality checks

got an industrial salinity sensor used in a wastewater circulation line test. wiring and setup were simple enough, nothing tricky. the industrial salinity sensor responds in a reasonable way when salinity changes, not too slow or overly sensitive. had to adjust calibration slightly at the beginning, but after that it’s been consistent during continuous operation.
