Hach 3728E2T Electrodeless Conductivity Sensor

The Hach 3728E2T is an electrodeless (inductive) conductivity sensor designed for reliable measurement in harsh industrial and water treatment environments. Utilizing a convertible mounting style with PFA/Teflon wetted materials, it offers excellent chemical resistance and durability, making it ideal for applications such as wastewater treatment, chemical processing, food and beverage, and pharmaceutical industries. Key features include non-contact measurement to prevent fouling, a wide conductivity range, integrated temperature compensation, and compatibility with Hach controllers like the sc200 or sc1000. Advantages over electrode-based sensors include reduced maintenance due to no electrode wear, suitability for high-conductivity or corrosive fluids, and robust performance in dirty or viscous media. Drawbacks may include higher initial cost and the need for proper installation to avoid air bubbles affecting readings. This 2012 model appears new or unused based on packaging and condition, with included user manual. It provides accurate, real-time data for process control, ensuring compliance and efficiency. For detailed specs, refer to Hach datasheets; model decoding indicates '3728' series for inductive type, 'E2' for specific configuration, and 'T' for Teflon material.
