Water Quality Sensors

Introduction to Water Quality Sensors

What is it?

Water quality sensors are devices that measure and monitor different parameters of water quality such as pH, temperature, dissolved oxygen, turbidity, conductivity, and chemical concentrations. These sensors are used to assess the suitability of water for various applications such as drinking water supply, industrial processes, and wastewater treatment.

Why we use it?

We use water quality sensors to ensure that water meets specific quality standards, optimize water usage, and reduce environmental impact by monitoring water quality.

How it works?

The sensor typically contains a sensing element, such as an electrode or optical sensor, which interacts with the water to produce a signal proportional to the parameter being measured. The device then calculates the water quality based on the magnitude of the signal produced.

Major brands that manufacture it

Some of the major brands that manufacture water quality sensors include Hach, YSI, Thermo Fisher Scientific, and Hanna Instruments.


There are different types of water quality sensors, including pH sensors, dissolved oxygen sensors, turbidity sensors, conductivity sensors, and chemical sensors. Some models may also feature additional functions, such as temperature sensing or wireless connectivity.

How do we select it?

When selecting a water quality sensor, consider factors such as measurement range, accuracy, response time, compatibility with the water matrix, and communication protocols. Also, make sure the sensor is compatible with your existing control and automation systems.

How to install it?

Water quality sensors should be installed in the location where water quality needs to be measured, such as a pipe or tank. They should be mounted securely using appropriate fittings or adapters, and any necessary wiring connections should be made to the building automation system or controller.

Wire connections required to receive the signals

The wire connections required to receive the signals from a water quality sensor may vary depending on the specific device and building automation system. Typically, they will require a power supply connection and a communication signal wire that connects to the building automation system or controller. It's important to refer to the manufacturer's installation instructions for proper wiring connections.
