EC1

The EC1 Conductivity, TDS & Salinity Meter is a lightweight, portable instrument designed to provide fast and accurate measurements for routine water quality monitoring. Capable of measuring conductivity, total dissolved solids (TDS), salinity and temperature, the EC1 is an ideal solution for engineers, water treatment professionals and technicians carrying out testing in the field or laboratory.

Designed for everyday use, the EC1 combines reliable performance with a simple, user-friendly interface, allowing you to monitor multiple water quality parameters using a single handheld instrument.

Built for Field Testing

Whether you're monitoring cooling systems, process water, potable water or environmental samples, the EC1 has been designed to withstand the demands of routine field work. Its compact, waterproof design floats if accidentally dropped into water, providing added confidence when working around tanks, reservoirs and open water systems.


The clear display provides quick access to conductivity, TDS, salinity and temperature readings, while the data hold function makes it easy to record results during testing. Automatic shut-off helps maximise battery life, ensuring the instrument is always ready when needed.

Accurate Multi-Parameter Measurement

By combining four essential water quality measurements into one portable device, the EC1 simplifies routine testing and reduces the need to carry multiple instruments. High measurement accuracy and automatic temperature compensation help deliver reliable, repeatable results across a wide range of applications.


Weighing just 74 g, the EC1 is comfortable to carry throughout the working day, making it an ideal choice for both routine monitoring and on-site troubleshooting.
