Hanna Conductivity Mini Controller (0 - 1999 µS/cm) 115/230VAC - BL983313-1

Hanna BL983313-1 Conductivity Mini Controller is a reliable and industrial-grade solution designed for precise measurement and control of electrolytic conductivity in liquids across a wide range of applications including water treatment, chemical processing, and manufacturing. Operating within a measurement range of 0 to 1999 µS/cm, this controller is ideal for processes where maintaining accurate conductivity levels is critical for system efficiency, product quality, and regulatory compliance. Its panel-mounted design allows seamless integration into control systems, making it suitable for both laboratory setups and industrial automation environments.

This controller is particularly useful in applications that require real-time monitoring and automated dosing control. It offers both manual and automatic dosing modes, enabling users to operate based on specific process needs. In automatic mode, the dry contact relay activates when the conductivity exceeds the user-defined set point, allowing direct control of dosing pumps or solenoid valves to maintain optimal conditions. The adjustable set point across the full range provides flexibility for fine-tuned process management in diverse applications.

Designed for ease of operation and durability, the BL983313-1 features a multicolor LED indicator that provides instant visual feedback on system status, helping operators quickly identify operating conditions and simplify maintenance. Manual calibration is performed using a dedicated CAL trimmer, ensuring consistent and accurate readings over time. The controller also includes automatic temperature compensation from 5°C to 50°C (β = 2%/°C), which ensures reliable performance even when process temperatures fluctuate.

Built to withstand demanding environments, the unit is housed in a fire-retardant plastic casing with a splash-resistant protective front cover that guards against dust and liquid ingress. The dosing relay is rated up to 2A at 250 VAC or 30 VDC and is fuse protected for safe operation in industrial conditions. Powered by a standard 115/230 VAC supply, it offers broad compatibility for various installations.

With compact dimensions of 83 x 53 x 99 mm and a lightweight design of approximately 300 g, the BL983313-1 is easy to install in control panels and process cabinets. Widely used in water treatment plants, environmental monitoring stations, industrial processing units, and laboratories, this controller provides a dependable and cost-effective solution for continuous conductivity monitoring and dosing automation.
