Hanna Conductivity Mini Controller (0.00-10.00 mS/cm) - BL983327-0 | 12VDC

Hanna BL983327-0 Conductivity Mini Controller is a compact and high-precision solution designed for accurate monitoring and control of conductivity in industrial, laboratory, and water treatment applications. Operating within a measurement range of 0.00 to 10.00 mS/cm, this controller is ideal for processes such as boiler feed monitoring, water treatment systems, and automated dosing setups where maintaining optimal conductivity levels is essential for efficiency, safety, and compliance. Its panel-mounted design ensures easy integration into control systems, making it suitable for continuous process monitoring.

This controller is particularly useful in applications requiring automated response to changing conductivity levels. It offers both manual and automatic dosing modes, allowing operators to customize control based on process needs. In automatic mode, the built-in dry contact relay activates when the measured conductivity exceeds the preset threshold, enabling seamless control of solenoid valves, dosing pumps, or other actuators for corrective action. The adjustable setpoint across the full range provides flexibility for fine-tuning system performance.

Designed for durability and user convenience, the BL983327-0 features a large LCD display with a protective cover that ensures clear visibility and safeguards the interface from dust, moisture, and industrial exposure. A multicolor LED indicator provides instant visual feedback on system status, helping operators quickly identify operating conditions and alarms. The controller also supports manual calibration via an accessible CAL trimmer, allowing routine adjustments to maintain measurement accuracy over time.

To ensure reliable performance in varying conditions, the unit includes automatic temperature compensation from 5 to 50°C (β = 2%/°C), maintaining consistent readings despite environmental fluctuations. The fire-retardant plastic casing enhances safety in industrial environments, while the dosing relay (rated up to 2A at 250 VAC or 30 VDC) ensures compatibility with a wide range of control circuits. Powered by a 12 VDC adapter and weighing approximately 200 g, it is lightweight yet robust for long-term operation.

Widely used in water treatment plants, laboratories, boiler systems, and industrial process automation, the BL983327-0 provides a reliable, efficient, and user-friendly solution for conductivity-based process control Conductivity Controller
