Product Description

Hanna BL983320-2 Conductivity Mini Controller is a compact and high-precision process control instrument designed for accurate monitoring and regulation of electrolytic conductivity in low-range applications. Operating within a range of 0.0 to 199.9 µS/cm, this controller is ideal for ultrapure water systems, ion exchange processes, reverse osmosis (RO), distillation units, and laboratory environments where even minor conductivity variations must be closely controlled to maintain quality and compliance.

Engineered for seamless automation, the controller supports both manual and automatic dosing modes. In automatic mode, the integrated dry contact relay activates when the measured conductivity exceeds the user-defined setpoint, enabling direct control of dosing pumps, solenoid valves, or other process equipment. The adjustable overdose timer further enhances process safety by preventing excessive dosing. With a 4–20 mA output signal, the BL983320-2 can be easily integrated into SCADA or PLC systems, making it suitable for advanced process control and centralized monitoring.

Designed for accuracy and reliability, the controller offers a resolution of 0.1 µS/cm and an accuracy of ±2% full scale, ensuring dependable readings for critical applications. Automatic temperature compensation from 5 to 50°C (β = 2%/°C) maintains measurement stability under varying thermal conditions, while manual calibration via a CAL trimmer allows fine adjustments to match specific process requirements.

The BL983320-2 features a large LCD display with a protective cover for clear visibility and durability, along with a multicolor LED indicator that provides instant visual feedback on system status. Its fire-retardant casing ensures safe operation in industrial environments, while the compact panel-mounted design (93 x 53 x 99 mm) and lightweight construction (approx. 300 g) allow easy installation in control panels.

Widely used in water treatment plants, pharmaceutical production, laboratory testing, and industrial process control, the BL983320-2 delivers a reliable combination of precision, automation capability, and durability. It is an ideal solution for professionals requiring accurate conductivity monitoring and efficient process control in low-conductivity applications Conductivity Controller
