A TDS + EC Meter is a digital water-testing instrument used to measure Total Dissolved Solids (TDS) and Electrical Conductivity (EC) in water and aqueous solutions. Many models also provide temperature measurement.
EC stands for Electrical Conductivity. It measures the ability of a solution to conduct electrical current, which is related to the concentration of dissolved ions in the solution.
The meter uses an electrical sensor/probe to measure the conductivity of the liquid. The EC measurement can then be converted into an estimated TDS value using the meter's programmed conversion factor.
The range depends on the specific model. Different meters are designed for applications ranging from low-conductivity purified water to higher-conductivity industrial or process water.
Yes. Regular calibration helps maintain measurement accuracy. Calibration is normally performed using an appropriate standard conductivity calibration solution recommended for the meter.
A standard TDS Meter primarily provides a TDS reading, while a TDS + EC Meter provides both TDS and electrical conductivity measurements, giving users more information about the dissolved ionic content of the sample.
A quality digital TDS + EC meter provides fast, convenient, and easy-to-read measurements of both dissolved solids and conductivity. It is a practical solution for water-treatment professionals, laboratories, agricultural users, industrial applications, and routine water-quality monitoring.
