Hanna TDS Mini Controller (0.00 to 10.00 ppt) - BL983318 -115/230VAC

The BL983318 Mini TDS Controller is a compact, panel-mounted instrument engineered for accurate monitoring and control of total dissolved solids (TDS) in industrial and laboratory process streams. Featuring a large LCD with a protective cover, this controller offers high clarity operation in a robust enclosure. It measures TDS from 0.00 to 10.00 ppt (g/L) with ±2% full-scale accuracy, making it suitable for water treatment, boiler control, chemical dosing, and similar applications.

BL983318 supports both automatic and manual dosing modes, using a 2A-rated relay output to control a solenoid valve, dosing pump, or other equipment. In automatic mode, the relay is activated when the TDS reading exceeds the programmable set point, enabling seamless system integration for maintaining water quality or process consistency. A conversion factor of 0.5 ensures precision (1.00 mS/cm = 0.50 ppt). The adjustable TDS set point covers the full range up to 10 ppt.

• Measures TDS from 0.00 to 10.00 g/L (ppt) with 0.01 g/L resolution.
• Automatic temperature compensation from 5°C to 50°C (β = 2%/°C).
• Manual calibration and CAL trimmer for reliable daily operation.
• 115/230 VAC (50/60Hz) model offers flexibility for facility requirements.
• Relay output: maximum 2A (fuse protected), 250 VAC, 30 VDC.
• Fire-retardant plastic casing for safety and splash resistance.
• Multicolor LED status indicator for fast diagnostics and alerts.
• Dimensions: 83 x 53 x 99 mm; model weight: 300 g.
• Supplied with user manual and mounting accessories.

Typical use cases include industrial water treatment, laboratory feedwater monitoring, process tank dosing management, and automated water quality control in HVAC, chemical, and manufacturing sectors.
