Hanna Conductivity Controller (0.00 to 19.99 µS/cm) - BL983322-1 | 115/230VAC

Built for continuous process control, the controller supports both automatic and manual dosing modes, offering flexibility for different operational requirements. In automatic mode, the integrated dry contact relay (2A, fuse-protected) activates when conductivity exceeds the user-defined setpoint, enabling direct control of solenoid valves or flow systems for immediate corrective action. This makes it especially effective for switching DI water tanks, regulating purified water flow, and maintaining consistent process conditions. The adjustable overdosing timer further enhances safety by preventing excessive dosing and ensuring controlled, stable operation.

Designed with user convenience and durability in mind, the BL983322-1 features a large LCD display with a protective cover for clear, real-time readings, even in challenging environments. A multicolor LED indicator provides quick visual feedback on system status, simplifying monitoring and troubleshooting. The controller includes manual calibration via a CAL trimmer for precise adjustment, along with automatic temperature compensation from 5 to 50°C (β = 2%/°C), ensuring accurate readings despite temperature variations.

Encased in a rugged, fire-retardant housing, the controller offers enhanced safety and reliability in industrial and laboratory installations. Its compact panel-mounted design (83 x 53 x 99 mm) and lightweight build (approximately 300 g) allow easy integration into control panels. Operating on a 115/230VAC, 50/60Hz power supply, it is compatible with global industrial systems.

Widely used in water treatment facilities, laboratory research, pharmaceutical production, and high-purity manufacturing processes, the BL983322-1 provides a dependable combination of precision, automation, and durability. It is an ideal choice for professionals who require accurate conductivity monitoring and control in critical low-conductivity applications. Conductivity Controller
