  • Developed to be an inexpensive solution for the horticulturist, the HI981412 pH Controller and Dosing Pump is a system engineered for maintaining the pH of nutrient solutions and irrigation water. Simply insert the probe and injection valve in-line with the recirculation pump and provide the chemical to be dosed.

    • Available in multiple configurations.
    • Programmable alarm system and multicolored LCD display
    • Perfect for small hydroponics systems

     

    Peristaltic Dosing Pump

    The powerful built-in peristaltic pump uses a stepper motor which does not have any gears or brushes providing for a long life with little maintenance.

    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.

    Quick Connect Probe Input

    The Quick Connect DIN connector creates a waterproof seal with the meter making it ideal for reducing electrical noise issues with the connection caused by humid environments. 

    GroLine pH/Temperature Probe

    The HI981412 uses the HI10063 amplified probe that incorporates both pH and temperature sensors and connects to the controller with a single waterproof Quick Connect DIN connector.

    • Built-in amplifier
    • PVDF body
    • 1/2” threaded fitting for insertion to an in-line “T” fitting or the flow cell
