Product Description
The Hanna BL983324-12VDC TDS Mini Controller is a compact, panel-mounted process controller engineered to deliver accurate measurements of total dissolved solids (TDS) in the range of 0.0 to 49.9 ppm (mg/L). This unit is designed for industrial, laboratory, and water treatment applications where precise monitoring and dosing control is critical, such as in reverse osmosis (RO) systems, ion exchange units, and distillation plants.
Featuring a large LCD display with a protective cover, the controller enables clear and at-a-glance readouts in challenging environments. The device supports both automatic and manual dosing, activating a dry contact relay when TDS levels exceed the set point—ideal for driving dosing pumps or opening solenoid valves. The fire-retardant casing and multicolor LED indicator reflect a commitment to operational safety and simple status verification.
- Panel-mounted, microcontroller-driven process controller for 0.0–49.9 ppm (mg/L) TDS measurement.
- Large, clear LCD with integrated dust and splash protection cover for robust performance.
- Selectable automatic/manual dosing operation, with emergency over-dosing control from 5–30 min.
- 0.5 EC-to-TDS conversion factor (1.0 µS/cm = 0.5 ppm/mg/L) for accurate, application-specific readings.
- Dosing relay specification: max 2A, 250 Vac, 30 VDC, with integrated fuse protection.
- Automatic temperature compensation range: 5–50°C (41–122°F), β = 2%/°C.
- Manual calibration via front CAL trimmer for straightforward operator adjustments.
- Protective, fire-retardant enclosure ensures safe, long-term operation in demanding environments.
- Supports high-purity water quality monitoring in RO, DI, and other critical water preparation systems.
- Package includes 12 VDC adapter, mounting hardware, and quick-start guide.
The BL983324-12VDC is suitable for industrial, laboratory, water treatment, and commercial water treatment systems. Explore more laboratory mini controllers in the EnvMart catalog for diverse process control solutions.
