Hanna Conductivity Mini Controller (0 - 1999 µS/cm) 12VDC - BL983313-0

This controller is particularly valuable in applications such as water purification systems, chemical dosing processes, and industrial fluid management, where real-time monitoring and automated response are critical. It offers both automatic and manual dosing modes, allowing users to control connected equipment like dosing pumps or solenoid valves based on process requirements. In automatic mode, the dry contact relay activates when the conductivity exceeds the preset threshold, enabling timely corrective action and ensuring process stability.

Designed for reliability and ease of use, the BL983313-0 features a multicolor LED indicator that provides instant visual feedback on operational status, helping operators quickly assess system conditions. The adjustable set point across the full measurement range allows precise control, while the built-in CAL trimmer enables manual calibration for fine-tuning accuracy. Automatic temperature compensation from 5 to 50°C (β = 2%/°C) ensures consistent readings even when process temperatures vary.

Built to perform in demanding environments, the controller is housed in a fire-retardant casing with a clear protective front cover that shields it from dust, moisture, and accidental splashes. Its dosing relay supports up to 2A at 250 VAC or 30 VDC and includes fuse protection for safe operation. With compact dimensions of 83 x 53 x 99 mm and a lightweight design of approximately 200 g, it is easy to install and integrate into various panel configurations.

Widely used in industrial automation, laboratory setups, water treatment plants, and chemical processing systems, the BL983313-0 provides a reliable, cost-effective, and user-friendly solution for conductivity monitoring and dosing control, ensuring efficient and accurate process management.
