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.
