Conductivity, TDS, Salinity and Resistivity Sensors
Conductivity sensors are used to measure the ion concentration of water for process control, dosing, desalination, boiler water, cooling tower and wastewater applications. TDS values are often calculated from conductivity, salinity monitoring is useful for seawater and environmental projects, and resistivity measurement is commonly used for RO, pure water and ultrapure water systems.
LOOTEST can provide contacting conductivity probes, four-electrode conductivity sensors and toroidal inductive conductivity sensors according to the measuring range, water quality, temperature, chemical compatibility and maintenance conditions. Online conductivity sensors can be matched with transmitters, controllers, RS485 Modbus or 4-20mA output for PLC, SCADA, dosing pumps and OEM monitoring equipment.

How to choose an online conductivity sensor supplier
For B2B purchasing, conductivity sensor selection should start with the target parameter: conductivity, TDS, salinity or resistivity. Then confirm the water type, measuring range, temperature, pressure, installation position, output signal and cleaning frequency. A stable online conductivity sensor should match both the measurement task and the maintenance conditions of the project.
- RO and pure water: choose conductivity or resistivity monitoring with suitable low-range accuracy and stable temperature compensation.
- Cooling tower and boiler water: use conductivity and TDS data to support blowdown control, chemical dosing and water cycle management.
- Chemical process water: check material compatibility, temperature, pressure and whether a toroidal conductivity sensor is needed for high concentration or coating risk.
- Wastewater and reuse water: select a probe structure that can handle suspended solids, changing water quality and regular cleaning.
- Remote monitoring: digital RS485 conductivity sensors are useful when conductivity data needs to connect with PLC, SCADA or cloud monitoring systems.
FAQ for conductivity, TDS and salinity sensors
What is a conductivity sensor in water quality monitoring?
A conductivity sensor measures how easily water conducts electrical current, which reflects the amount of dissolved ions in the water. It is widely used in industrial water treatment, process water, RO systems, cooling towers, boiler water, wastewater and environmental monitoring.
What is the difference between conductivity and TDS?
Conductivity is a direct measurement of ionic conductivity. TDS is usually calculated from conductivity by applying a conversion factor, so the relationship depends on the water composition and application.
What is the difference between conductivity and salinity?
Salinity is often calculated from conductivity and temperature when the main concern is salt content, such as seawater, aquaculture, brackish water and environmental monitoring projects.
What is resistivity in water quality monitoring?
Resistivity is the inverse of conductivity. It is commonly used for pure water and ultrapure water systems where very low ion concentration needs to be monitored.
Should I choose an inductive or contacting conductivity sensor?
Contacting conductivity sensors are often used for clean water and lower-range applications. Toroidal or inductive conductivity sensors are often selected for higher conductivity ranges, chemical solutions, dirty water or applications with coating risk.
Can conductivity sensors connect to PLC or SCADA?
Yes. Depending on the selected model and controller configuration, LOOTEST conductivity sensors can support RS485 Modbus, 4-20mA or relay output for PLC, SCADA, dosing control and remote monitoring systems.
