Hanna Resistivity Mini Controller - BL983314-12VDC

Hanna BL983314 Resistivity Mini Controller is a compact, versatile, and high-precision instrument engineered for continuous monitoring and control of resistivity in ultra pure water systems, reverse osmosis (RO) plants, and water conditioning processes. Designed to deliver reliable and accurate measurements, this controller features a resistivity measurement range of 0.00 to 19.90 MΩ·cm with a fine resolution of 0.10 MΩ·cm, making it ideal for critical industrial and laboratory applications where water purity is essential.

The controller operates on a 12 VDC power supply (adapter included), ensuring safe and efficient integration into low-voltage systems and automated process setups. It is equipped with a HI3314 resistivity probe featuring a 2 m cable, allowing flexible installation and stable performance. Automatic temperature compensation with selectable β coefficients (2.4, 3.5, or 4.5 %/°C) ensures accurate readings even under varying environmental conditions, maintaining consistency in measurement results.

The BL983314 offers user-friendly operation with manual setpoint and calibration trimmer adjustments, enabling precise control and easy configuration. Its integrated relay system (2A max, 250 VAC/30 VDC) activates dosing or alarm mechanisms when resistivity falls below the defined threshold, allowing seamless control of pumps, solenoids, or warning systems. Additionally, selectable overdose protection enhances operational safety, preventing overcorrection in automated processes.

Built with a durable, fire-retardant enclosure and a splash-resistant cover, the controller is designed to withstand demanding industrial environments. Its compact dimensions (83 × 53 × 99 mm) make it suitable for panel mounting or space-constrained installations, while low power consumption of 10 VA ensures energy-efficient continuous operation. The unit is factory-calibrated, minimizing setup time and maintenance efforts.

Ideal for applications such as industrial water treatment, laboratory water purity monitoring, RO system management, and ultra pure water quality control, the Hanna BL983314 ResistivityMini Controllers delivers dependable performance and automation. Enhance your process efficiency with Hanna’s advanced control solutions, designed for precision, durability, and seamless integration in rigorous environments.
