Product Description

Hanna BL983320-0 Conductivity (EC) Controller is a compact and high-precision process control instrument designed for accurate monitoring and regulation of low-range conductivity in industrial, laboratory, and water treatment applications. Operating within a measurement range of 0.0 to 199.9 µS/cm, this controller is ideal for processes such as reverse osmosis (RO), ion exchange, distillation systems, and ultrapure water management where maintaining strict conductivity levels is essential for system efficiency and product quality.

This controller supports both automatic and manual dosing modes, providing flexibility for various operational needs. In automatic mode, the internal dry contact relay activates when the measured conductivity exceeds the user-defined setpoint, enabling direct control of solenoid valves, pumps, or dosing systems for real-time process adjustment. The adjustable overdosing protection, typically ranging from 5 to 30 minutes, helps prevent excessive chemical addition and ensures process safety and stability.

Designed for ease of use and reliability, the BL983320-0 features a large LCD display with a protective cover for clear visibility and enhanced durability in demanding environments. It includes automatic temperature compensation from 5°C to 50°C (β = 2%/°C), ensuring consistent and accurate readings despite fluctuations in process temperature. Manual calibration via an onboard CAL trimmer allows users to fine-tune the controller for precise performance over time.

The unit is housed in a rugged, fire-retardant casing that enhances safety and ensures long-term durability in industrial settings. A multicolor LED indicator provides quick visual feedback on system status, simplifying monitoring and troubleshooting. Powered by a 12 VDC adapter and weighing approximately 200 g, it is lightweight and easy to integrate into control panels and process systems.

Widely used in industrial water treatment plants, ETP/STP systems, laboratory process control, manufacturing units, and environmental monitoring setups, the BL983320-0 delivers a dependable combination of precision, automation capability, and durability, making it an ideal solution for conductivity-based process control in low-range applications Conductivity Controller
