Product Description

Hanna BL983319-2 Mini TDS Controller is a compact and high-performance instrument designed for accurate measurement and control of total dissolved solids (TDS) in water and process streams. With a measurement range of 0–1999 ppm (mg/L), this controller is ideal for applications in water treatment, hydroponics, agriculture, and laboratory environments where maintaining precise TDS levels is essential for process efficiency and quality control.

Engineered for panel-mounted installation, the BL983319-2 features a large LCD display combined with a multicolor LED indicator, providing clear visibility of readings and real-time operational status. The unit is protected by a transparent cover and housed in a fire-retardant plastic casing, ensuring durability, safety, and long-term reliability in demanding industrial conditions.

The controller supports both automatic and manual dosing modes, allowing seamless integration with dosing pumps and control systems. A built-in dry contact relay activates when the measured TDS value falls below the user-defined set point, enabling automatic addition of nutrients or chemicals to maintain optimal solution concentration. This makes it especially useful in hydroponic nutrient management and water treatment processes.

The device includes a 4–20 mA analog output for easy integration with PLCs, SCADA systems, and other industrial monitoring platforms. Manual calibration via a CAL trimmer ensures precise adjustment and measurement accuracy of ±2% full scale, with a resolution of 1 ppm.

Automatic temperature compensation from 5 to 50°C (β = 2%/°C) ensures consistent and reliable readings even under fluctuating environmental conditions. Adjustable dosing set points and an over-dosing timer provide enhanced control over process operations.

With compact dimensions of 83 × 53 × 99 mm, the controller is easy to install in control panels and occupies minimal space. Its rugged design supports continuous, unattended operation in industrial and laboratory setups.

Widely used in water treatment plants, agricultural nutrient dosing systems, laboratories, and chemical processing industries, the Hanna BL983319-2 ensures precise TDS monitoring and efficient process control.

Enhance your automation and monitoring systems with Hanna’s advanced control technology, designed for accuracy, durability, and seamless integration in professional applications Mini Controllers
