Product Description
Professional Conductivity Mini Controller with Low-Range Relay for Automated EC Monitoring
The Hanna BL983317-1 is a compact, professional-grade conductivity mini controller designed for automated EC (electrical conductivity) monitoring and control from 0.00 to 10.00 mS/cm. Featuring a low-range relay output, this controller continuously monitors conductivity levels and automatically activates connected equipment to maintain optimal water chemistry in hydroponics, aquariums, aquaculture, and water treatment applications.
Key Features:
Low-Range EC Monitoring: Measures conductivity from 0.00 to 10.00 mS/cm—ideal for hydroponics, aquariums, and low-conductivity water treatment applications
Automated Relay Control: Programmable relay output automatically activates dosing pumps, alarms, or other equipment when EC levels exceed setpoints
Compact Mini Design: Space-saving controller fits easily in tight spaces and control panels
Continuous Monitoring: 24/7 real-time EC monitoring eliminates manual testing and ensures consistent water quality
Easy Programming: Simple interface for setting EC setpoints, relay activation points, and alarm thresholds
Visual Display: Clear LCD screen shows current EC readings and system status
Alarm Functions: Visual and audible alarms alert you to out-of-range conditions or system faults
Durable Construction: Built for reliable 24/7 operation in demanding commercial and industrial environments

Applications:
Essential for hydroponic nutrient solution EC control (automated dosing), aquarium conductivity monitoring (reef tanks, planted tanks), aquaculture water quality management (fish farms, hatcheries), water treatment plant automation, reverse osmosis system monitoring, industrial process water control, greenhouse irrigation management, and any application requiring automated low-range conductivity monitoring and control.
How It Works:
The BL983317-1 continuously monitors EC levels via a connected conductivity probe. When EC readings exceed your programmed setpoint, the relay automatically activates connected equipment—such as dosing pumps to add nutrients or dilution systems to reduce conductivity. This ensures optimal water chemistry 24/7 without manual intervention.
Why Choose Automated EC Control?
Manual EC testing and adjustment is time-consuming, inconsistent, and prone to human error. The BL983317-1 automated controller eliminates these problems by continuously monitoring EC and making precise adjustments 24/7. This ensures optimal nutrient levels in hydroponics, stable water chemistry in aquariums, and consistent water quality in industrial applications—while reducing labor costs and preventing crop damage or fish stress from EC fluctuations.
Installation & Setup:
Mount the compact controller in your control panel or near your system, connect a compatible conductivity probe (sold separately), wire the relay output to your dosing pump or control equipment, program your desired EC setpoint and relay activation parameters, and the system handles the rest. Professional installation recommended for commercial applications.
Maintenance:
Regular maintenance includes calibrating the conductivity probe with standard solutions, checking relay operation, inspecting probe connections, and cleaning the probe as needed. The system's alarm functions alert you to any issues requiring attention.
Note: Conductivity probe sold separately. Compatible with Hanna conductivity probes with appropriate range. Regular calibration with EC standard solutions (e.g., 1413 µS/cm, 12.88 mS/cm) recommended for optimal accuracy. Professional installation recommended for commercial applications.
