Conductivity measures a solution’s ability to conduct electric current, which directly reflects the concentration of ions present—such as salts, acids, or alkalis. It is a key parameter in water quality monitoring, industrial process control, and environmental applications. Conductivity sensors work by applying a voltage between two or more electrodes submerged in a solution and measuring the resulting current. The more ions present, the higher the conductivity.

HH SCIENCE conductivity sensors are engineered for precision, durability, and versatility. We offer both two-electrode and four-electrode designs using materials like 316L stainless steel, graphite, and Hastelloy for optimal performance in ultra-pure water, wastewater, seawater, or aggressive chemical environments. With built-in temperature compensation, digital MODBUS RTU output, and IP68-rated waterproof protection, our sensors deliver reliable results in both simple and complex applications.

Whether you need high-accuracy lab-grade probes or rugged industrial units for continuous monitoring, HH SCIENCE offers models for every need. For OEM partners, we provide full customization—including electrode design, cable configuration, thread size, and protocol integration.

Choose HH SCIENCE conductivity sensors for long-term stability, minimal maintenance, and trusted accuracy across a wide range of industries—from water treatment to food & beverage to pharmaceuticals.
