Hanna Conductivity Controller (0.00 to 19.99 µS/cm) - BL983322-1 | 115/230VAC

The BL983322-1 Conductivity Controller is engineered for precise, real-time monitoring of electrolytic conductivity from 0.00 to 19.99 µS/cm in process streams and laboratory environments. This panel mounted unit features a large LCD with multicolor LED status indication and robust, fire retardant casing to ensure safe operation in demanding conditions.

Supporting both automatic and manual dosing modes, the integrated dry contact relay (2A, fuse protected) can actuate solenoids or valves when the measured value exceeds the adjustable setpoint. This makes the controller ideal for applications such as switching DI water tanks, managing flow of purified water, or monitoring conductivity in distillation and ultrapure water systems.

• Measurement range: 0.00 to 19.99 µS/cm, suitable for ultrapure water and process quality control.
• EC accuracy of ±2% full scale and manual calibration with CAL trimmer for reliable operations.
• Adjustable dosing setpoint with automatic temperature compensation (5–50°C, β =2%/°C).
• Overdosing control timer to prevent accidental overdosing and allow safe, consistent dosing cycles.
• Dimensions: 83 x 53 x 99 mm (3.3 x 2.1 x 3.9 in), weight: approximately 300 g for model -1.
• Power supply: 115/230VAC, 50/60Hz—compatible for international industrial settings.
• Fire retardant enclosure enhances safety in plant and laboratory installations.
• Clear display and multicolor LED for real-time status monitoring and alarm conditions.

This controller suits industrial, water treatment, laboratory, and manufacturing environments where continuous, automated conductivity monitoring and control are required. It is especially valuable for monitoring DI water, ensuring process purity for semiconductor fabrication, pharmaceuticals, and distilled water systems.
