Hanna GroLine Nutrient Dosing System (HI981413)

Automated nutrient control for hydroponic and fertigation systems. The GroLine HI981413 is a wall-mounted controller with a built-in peristaltic dosing pump: it reads EC/TDS continuously and doses nutrient automatically to hold your set point, keeping feed strength steady between reservoir checks.

• Controller with HI30033 EC/TDS/temperature probe (PVDF body, 1/2" NPT thread, Quick Connect DIN)
• EC 0.00-10.00 mS/cm, 0.01 resolution, +/-2% F.S. accuracy; TDS 0-9900 ppm with selectable conversion factor (0.45-0.99)
• On/Off or Proportional dosing control - set point 0.10-10.00 mS/cm (EC or TDS units)
• Peristaltic pump doses 0.5-3.5 L/h; brushless stepper motor, self-priming; manual prime control
• High/low and tank-level alarms, overtime overdose protection, color-coded LCD (green = normal, red = alarm)
• IP65 wall-mount casing, alarm relay output, input for a level controller or flow switch
• In the box (base configuration): controller, HI30033 probe, 1413 uS/cm conductivity calibration solution, power connection cable, instruction manual
• In-Line Mounting Kit adds: injector, pipe saddles, aspiration filter, valves, 5 m aspiration and dispensing tubing. Panel-Mounted Flow Cell adds: flow cell on mounting panel, injector, saddles, filter, valves, 5 m aspiration and 15 m dispensing tubing
• Pairs with the Hanna GroLine pH Dosing System (HI981412) for full pH + nutrient automation
