Product Description

Hanna BL983322-0 Conductivity Controller is a compact and high-precision solution designed for accurate monitoring and control of low-range electrolytic conductivity in laboratory and industrial process environments. Operating within a sensitive measurement range of 0.00 to 19.99 µS/cm, this controller is ideal for applications such as DI water quality monitoring, laboratory distillation systems, and automated chemical dosing processes where maintaining ultra-low conductivity levels is critical for system performance and product quality.

This controller supports both automatic and manual dosing modes, offering flexibility for different operational requirements. In automatic mode, the built-in dry contact relay activates when the measured conductivity exceeds the user-defined setpoint, enabling direct control of solenoid valves or dosing systems to maintain desired EC levels. The adjustable over-dosing timer, ranging from approximately 5 to 30 minutes, enhances process safety by preventing excessive correction cycles and ensuring stable operation.

Designed for user convenience and reliability, the BL983322-0 features a large LCD display with a protective cover that ensures clear visibility and durability in demanding environments. A multicolor LED indicator provides instant visual feedback on system status, simplifying monitoring and troubleshooting. Manual calibration via a front-mounted CAL trimmer allows precise adjustment, while automatic temperature compensation from 5°C to 50°C (β = 2%/°C) ensures consistent and accurate readings despite temperature fluctuations.

Built with a fire-retardant, compact casing, the controller offers enhanced safety and long-term durability for industrial installations. Powered by a 12 VDC adapter and weighing approximately 200 g, it is lightweight and easy to integrate into control panels and process systems. Widely used in water treatment plants, laboratory setups, industrial automation, and DI water systems, the BL983322-0 provides a dependable combination of precision, automation, and ease of use, making it an ideal choice for conductivity-based process control in low-range applications Conductivity Controller
