Hanna Resistivity Mini Controller - BL983314-115/230VAC

The BL983314 Resistivity Mini Controller enables precise continuous monitoring and control of ultra pure water, reverse osmosis, and water conditioning processes in industrial, laboratory, and water treatment settings. Operating from 115/230 VAC, this controller features a 0.00 to 19.90 MΩ·cm measurement range, suitable for applications requiring high-resistivity water quality.

• High-accuracy measurement with ±2% F.S. ensures process reliability.
• Adjustable setpoint from 0 to 19.90 MΩ·cm supports flexible dosing relay operation.
• Selectable temperature compensation (β = 2.4, 3.5, or 4.5 %/°C) maintains accurate readings under varying conditions.
• Alarm and dosing relay for seamless integration with pumps, solenoids, or alarm systems.
• Fire-retardant casing and splash-resistant cover optimize safety and longevity.
• Includes factory-calibrated system and HI3314 probe (2 m cable) for easy commissioning.
• Manual trimmers allow on-site calibration and setpoint adjustment.
• Compact enclosure with dimensions of 83 x 53 x 99 mm facilitates versatile mounting.
• Operates at 10 VA power consumption to ensure energy efficiency.
• Resistivity dosing relay operates at up to 2A, 250 VAC, or 30 VDC (contact closed when measurement is below setpoint).

Typical use cases include laboratory control panels, semiconductor water systems, pharmaceutical process water, HVAC water quality monitoring, and commercial water treatment plants. The controller's robust features and reliable operation make it indispensable for continuous water resistivity assurance.
