Hanna ORP Mini Controller – BL982411-115/230VAC

Hanna BL982411-1 ORP Mini Controller is a compact, high-performance process control instrument designed for continuous monitoring and precise dosing control of oxidation-reduction potential (ORP) in water treatment, industrial, laboratory, and process environments. Its space-saving design makes it an ideal solution for installations where panel space is limited, while still delivering reliable and accurate performance for critical process control applications.

The controller is compatible with any ORP electrode featuring a standard BNC connector, allowing seamless integration into existing systems. It supports both automatic and manual dosing modes, giving users flexibility for routine operation, maintenance, and troubleshooting. The adjustable dosing relay enables control of both oxidizing and reducing agents, making it suitable for a wide range of chemical treatment processes.

Equipped with a large LCD display, the BL982411-1 provides clear, real-time visualization of ORP values, ensuring easy monitoring and quick adjustments. The controller offers a programmable setpoint range of 0.0 to 199.9 ppm (mg/L) with a resolution of 0.1 ppm and an accuracy of ±2% full scale, ensuring precise and consistent control of process parameters.

The system includes an overdosing protection feature adjustable between 5 to 30 minutes, helping to prevent excessive chemical usage and enhancing operational safety. A manual calibration trimmer allows straightforward calibration, ensuring continued measurement accuracy. The relay output is rated at 2A (fuse protected) at 250 VAC/30 VDC, providing reliable control of connected dosing equipment such as pumps or solenoids.

Constructed with a fire-retardant enclosure, the controller ensures safe operation in industrial environments. It operates on a universal AC power supply (115/230 VAC, 50/60 Hz), offering flexibility for installation across different regions and systems. Its compact dimensions (83 × 53 × 99 mm) and lightweight design (approximately 300 g) make it easy to install in control panels or confined spaces.

Widely used in industrial process monitoring, laboratory automation, water and wastewater treatment plants, chemical dosing systems, and environmental compliance applications, the Hanna BL982411-1 ORP Mini Controller enhances process reliability and operational efficiency.
