pH in agriculture
Maintaining the correct pH of plant soil or hydroponics nutrient solution is an ongoing task. Macro and micro nutrients, as well as calcium and magnesium bloom boosters, require the correct pH for absorption into the plants root system.
The HI-981412 Groline pH Dosing System, easily assimilates into a nutrient/fertiliser system for soil and hydroponics.
It precisely monitors the pH using the HI-10063 pH/temperature probe and simultaneously controls the addition of acid or base (Up and Down reagents) using On/Off or proportional control to fine tune and maintain the optimum pH.
Growers can define the ideal set point for pH. The HI-981412 is a small dosing controller and can be easily setup for a stand-alone nutrient reservoir or be part of a modular control scheme with the HI-981413 Groline Nutrient Dosing controller.
To obtain a representative sample pH, the probe should be located at a spot that experiences good circulation. The probe can be used in a “sample pot” or reservoir or installed in a flow cell or re-circulation line. Perfect for drain-to-waste or recirculating systems.
Main Benefits
- Reduced installation time and costs
- Accessible and easy to maintain pH in a nutrient feeding system
- The HI-981412 Groline pH Dosing System is engineered to be an inexpensive solution for the horticulturist to have real-time monitoring and control of nutrient solutions to obtain and maintain the ideal pH for optimum results at all times.
Main Features
- Built-in peristaltic pump with On/Off or Proportional control
- Manual control for pump priming
- Overfeed protection using overtime safety timer
- Resumes dosing on restart in case of power failure
- Easy to read LCD display with intuitive, color-coded backlight
- Level input to stop control without reagents
- Probe detection and recognition
- Easy to navigate menu to program and adjust settings
- Wall-mounted design
- IP65-rated casing
About the HI-10063 Amplified pH/Temperature Probe
The HI-981412 uses the HI-10063 amplified probe that incorporates both pH and temperature sensors and connects to the controller with a single waterproof Quick Connect DIN connector.
The built in amplifier helps to reduce electrical noise from re-circulation pumps to provide for a stable, reliable measurement. The pH glass used is ideal for low conductivity water and provides for fast response.
The PVDF body of the probe has a 1/2” threaded fitting for insertion to an in-line “T” fitting or the flow cell. The back end part of the probe has 3/4” NPT threads for submersion/ tank mounting. The probe body has a hex fitting for tightening snuggly with a wrench.
