EC sensors

EC sensors

EC sensors continuously measure the electrical conductivity of water and provide real-time insight into the concentration of dissolved salts and nutrients. In horticulture, water treatment and industrial applications, EC is a critical parameter for maintaining water quality and nutrient balance. Unlike portable meters, EC sensors are permanently installed and provide continuous measurements for monitoring and automation systems. Looking to buy an EC sensor? Pay attention to measurement range, accuracy, response time and compatibility with your controller or monitoring system. Read more

What do you use an EC sensor for?

EC sensors are used to continuously monitor nutrient concentrations and dissolved salts in irrigation water, nutrient solutions and process water. In horticulture, they help optimise fertigation systems and maintain stable growing conditions. In water treatment and industrial applications, EC measurements are used to monitor water quality and detect deviations immediately. Continuous monitoring allows you to automate processes and react quickly to changing conditions.

Features of EC sensors

Our EC sensors are designed for accurate and stable long-term measurements. Many models feature automatic temperature compensation and are suitable for continuous immersion in liquids. Depending on the model, sensors are available with analogue or digital outputs for integration with controllers and dataloggers. Their robust construction ensures reliable operation in demanding environments such as greenhouses, industrial installations and water treatment systems.

Tips when buying an EC sensor
