Hanna Resistivity Mini Controller - BL983314-115/230VAC

Hanna BL983314 Resistivity Mini Controller is a compact and highly reliable instrument designed for precise, continuous monitoring and control of resistivity in ultra pure water systems, reverse osmosis (RO) units, and water conditioning processes. Built for industrial, laboratory, and water treatment environments, this controller offers a wide measurement range of 0.00 to 19.90 MΩ·cm, making it ideal for applications that demand high-resistivity water quality and strict process control.

Operating on 115/230 VAC, the BL983314 ensures seamless integration into standard power systems while maintaining energy efficiency with a low power consumption of 10 VA. It delivers high measurement accuracy of ±2% F.S., ensuring dependable and consistent readings for critical operations. The adjustable setpoint range from 0 to 19.90 MΩ·cm allows users to configure dosing and control actions with precision, supporting automated process optimization.

The controller features selectable temperature compensation with β coefficients of 2.4, 3.5, or 4.5 %/°C, ensuring accurate resistivity readings even under fluctuating temperature conditions. An integrated alarm and dosing relay system (up to 2A, 250 VAC or 30 VDC) enables automatic activation of pumps, solenoids, or alarm systems when resistivity falls below the defined threshold, enhancing operational control and safety. Manual trimmers for calibration and setpoint adjustment provide flexibility for on-site configuration and maintenance.

Constructed with a durable fire-retardant casing and a splash-resistant cover, the BL983314 is built to withstand demanding environments while ensuring long-term reliability. Its compact dimensions of 83 x 53 x 99 mm allow easy installation in control panels or space-constrained setups. The unit comes factory-calibrated and includes an HI3314 resistivity probe with a 2 m cable, ensuring quick setup and stable, temperature-compensated performance.

Ideal for use in laboratory control panels, semiconductor water systems, pharmaceutical process water, HVAC water monitoring, and commercial water treatment plants, the Hanna BL983314 Resistivity Mini Controllers provides dependable automation and precise water quality control. This complete set includes the BL983314 Mini Controller, HI3314 resistivity probe with 2 m cable, and user manual, making it a ready-to-install solution for professional applications.
