FAQ

Q1: What is the advantage of using graphite electrodes? ❯

Graphite electrodes resist corrosion, are easy to maintain, and ensure stable measurement in long-term applications.

Q2: What is the difference between TDS and conductivity? ❯

TDS refers to the total dissolved solids in water, while conductivity measures the ability of water to conduct electricity. TDS is often estimated from conductivity values using a conversion factor.

Q3: Can the TDS conductivity sensor be used in seawater? ❯

Yes, the sensor can be used in seawater and other high-salinity solutions, as long as the conductivity is within its measurement range.

tds conductivity sensor works well for water monitoring

I used this sensor for a water quality monitoring project and it has been performing well so far. The tds conductivity sensor was easy to connect through RS485, and the data communication with the monitoring system was stable. Calibration took a little attention during the first setup, but the readings have remained consistent after adjustment. A practical choice for continuous water parameter monitoring.
