Hanna Conductivity Mini Controller (0.00-10.00 mS/cm) - BL983317-12VDC

Hanna BL983317-12VDC Conductivity Mini Controller is a compact, efficient, and application-focused solution designed for precise conductivity measurement and automated dosing control in industrial, laboratory, and water treatment environments. With a measurement range of 0.00 to 10.00 mS/cm, this controller is ideal for monitoring and regulating conductivity in processes such as chemical dosing, hydroponics systems, wastewater treatment, and laboratory analysis where maintaining correct EC levels is essential for performance and product quality.

This controller is particularly useful in systems requiring real-time response and automation. It supports both manual and automatic dosing modes, allowing users to control pumps or solenoid valves based on conductivity levels. In automatic mode, the relay activates when the measured value exceeds the setpoint, enabling immediate corrective action such as nutrient addition or system flushing. The adjustable overdosing protection across the full range helps prevent excessive chemical dosing, ensuring process safety and efficiency.

Designed for accuracy and stability, the BL983317-12VDC includes automatic temperature compensation from 5 to 50°C (β = 2%/°C), ensuring consistent readings even when environmental conditions fluctuate. Manual calibration via an accessible CAL trimmer allows users to fine-tune measurements and maintain long-term accuracy. The large LCD display with a protective cover ensures clear visibility of readings, while the integrated multicolor LED indicator provides instant visual feedback on system status and alarms.

Built for durability, the controller features a fire-retardant casing that enhances safety in industrial and laboratory installations. Its compact panel-mount design (83 x 53 x 99 mm) and lightweight construction (approximately 200 g) make it easy to install in control panels or field setups. Operating on a 12VDC power supply, it is well-suited for both fixed and mobile applications.

Widely used in water and wastewater treatment plants, chemical processing, hydroponic systems, laboratory testing, and pilot-scale process control, the BL983317-12VDC offers a dependable combination of precision, flexibility, and ease of use. It is an ideal choice for professionals seeking reliable conductivity monitoring and dosing automation in diverse process environments Conductivity Controller
