Hanna In-line Conductivity probe with NTC sensor for immersion installation - HI7638

The HI7638 In-line Conductivity Probe with NTC Sensor is a specialized industrial sensor engineered for immersion installation in tanks or pipelines. This probe employs four platinum rings as electrodes, using potentiometric (four-ring) technology, which ensures consistently accurate conductivity measurements even in environments with fluctuating sample conductivity. The built-in NTC temperature sensor further enhances accuracy by providing automatic temperature compensation in real time.

Constructed with a PEI (polyetherimide) body, this probe provides excellent resistance to chemicals and mechanical stress, making it suitable for continuous industrial processes as well as laboratory analysis. Its four-ring platinum cell configuration dramatically reduces polarization and extends the range for reliable measurement, unlike conventional two-ring (amperometric) designs.

• Integrated NTC sensor achieves stable, precise conductivity readings across a wide temperature range.
• Four platinum rings ensure dependable detection of ion concentrations in water and other process samples.
• PEI construction is chemically robust and withstands aggressive industrial environments.
• Designed for easy immersion installation in pipelines, reactors, or tanks—ideal for automated and continuous monitoring systems.
• Automatic temperature compensation streamlines process control and improves data reliability.
• Suitable for water treatment plants, chemical industry operations, manufacturing process streams, and research laboratories.
