Conductivity / TDS / Salinity
TCD Conductivity / TDS / Salinity Analyzer
Conductivity / TDS / Salinity
Conductivity and concentration analyzer for industrial process water and chemical concentration monitoring.
- Four-electrode measurement for high accuracy and stability
- Conductivity, TDS, salinity and temperature in one analyzer
- Auto-range switching from pure water to concentrated solutions
Overview
A conductivity analyzer continuously measures the ability of water to conduct electrical current, which correlates directly with dissolved ion concentration — the basis for TDS, salinity and chemical concentration monitoring.
The TCD Conductivity/Concentration Analyzer uses a four-electrode measurement principle. As electric current flows through the liquid, ion movement generates a voltage difference between the measuring electrodes. This voltage signal is detected and transmitted to the analyzer, which calculates the conductivity of the liquid based on Ohm's Law.
Typical Applications
Features
- Four-electrode measurement technology for high accuracy and excellent stability
- Multi-parameter display: conductivity, TDS, salinity and temperature
- Auto-range switching automatically adjusts range and unit based on medium concentration
- Dual-thread design (top and bottom) supports flexible installation: submersible, flow-through, insertion and more
