LTH Electronics S400 Series pH/Redox Sensors

The LTH Electronics S400 Series pH/Redox Sensors provide precise, reliable measurement of pH and redox (ORP) potential in aqueous solutions. Each sensor combines a pH electrode, a redox electrode and a stable reference electrode, allowing accurate, simultaneous readings of both values from a single, convenient unit — ideal for processes where both parameters must be monitored together.

Built for demanding industrial environments, the S400 features a rugged design that resists damage, along with temperature compensation to maintain accuracy as process conditions change. Its compact form and straightforward installation make it easy to integrate into new or existing systems, and it is compatible with a wide range of LTH controllers and transmitters as well as most pH meters on the market.

The stable reference electrode ensures dependable long-term performance, reducing drift and maintenance. The S400 is well suited to water and wastewater treatment, aquaculture, environmental monitoring and general process pH/ORP control.
