Hanna TDS Mini Controller (0 to 1999 ppm) - BL983319-0 | 12VDC

The BL983319-0 Mini TDS Controller is a robust and compact industrial device designed for precise monitoring and control of total dissolved solids (TDS) in process water and solutions across a range from 0 to 1999 ppm (mg/L). Suitable for panel mounting, it is ideal for water treatment, hydroponics, industrial, laboratory, and agricultural dosing systems requiring continuous and reliable TDS measurement.

This controller features a large LCD display with a splash-resistant, protective cover for enhanced durability in demanding environments. It offers both automatic and manual control modes to operate dosing pumps or similar devices. In automatic mode, the integrated dry contact relay is activated when TDS readings fall below an adjustable set point, enabling direct control of dosing operations such as nutrient or chemical addition for precise management of solution quality.

• Range: 0 to 1999 ppm (mg/L) with 1 mg/L resolution for fine measurement.
• High accuracy of ±2% f.s. and manual calibration with trimmer for reliable operation.
• Automatic temperature compensation (ATC) over 5–50°C (41–122°F) with β = 2%/°C ensures stable readings in varying conditions.
• EC to TDS conversion factor of 0.65 for accurate correlation between conductivity and TDS levels.
• LED indicator with multicolor feedback for status monitoring, plus fire-retardant casing for safety.
• Panel mount dimensions: 83 x 53 x 99 mm for compact installation.
• Relay output: max 2A (fuse protected), 250 VAC/30 VDC enables direct actuation of dosing equipment.
• Set point, overdosing timeout, and relay control are fully adjustable for flexible dosing management.
• Manual calibration and temperature compensation ensure the instrument stays accurate over time.
• Supplied with 12 VDC adapter for convenient power integration.

Commonly used in laboratory water treatment, fertilization systems, hydroponic nutrient control, and industrial water quality management. Supporting industrial reliability, the BL983319-0 is well suited for manufacturing, agricultural, and commercial water process control applications.

Set includes the BL983319-0 mini controller and 12 VDC power adapter. Mounting hardware and electrode are typically supplied separately—refer to manufacturer guidelines for probe compatibility.
