The HI981413-10 Hanna Nutrient Dosing System is engineered for maintaining the concentration of fertilizer in the nutrient solution used in hydroponics and irrigation water.
The nutrient concentration in the water used for irrigation is critical for the successful propagation and growth of plants.
Simply insert the probe and injection valve in-line with the recirculation pump and provide the chemical to be dosed.
GroLine EC/Temperature Probe
Automatic Proportional Pump Control
The peristaltic dosing pump can be controlled by simple on/off or more advanced proportional control which helps prevents overshooting of the set point.
Adjustable Flow Rate The dosing pump flow rate is adjustable from 0.5 to 3.5L/h, allowing for better control in maintaining a desired set point.
Acid Tank Level/Flow Switch Input
A connection to an optional level controller or flow switch. This input can be used to disable the dosing pump when there is no chemical left in the reservoir tank or there is no flow due to the pump being turned off.
Multicolored LCD Display
A multi-colored LCD provides a quick way to see the status of the pool controller. The display will show green when operation normally and red while in an alarm state.
