Hanna Instruments GroLine pH Dosing System with HI10063 pH Probe

HI-981412-00 GroLine pH dosing system with HI-10063 pH probe
Maintaining the correct pH of plant soil or hydroponic 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.
High or Low mode Operation pump control:
• On/Off control using adjustable set point (4.00 - 10.00 pH) with adjustable hysteresis (0.10to 1.00 pH)
• Proportional control using adjustable set point (4.00 - 10.00 pH) with adjustable proportional band (0.10 to 2.00 pH)
• Startup delay timer at power-on (0 to 600 sec.)
• Pump flow control 0.5 to 3.5 Liter/hour (0.13 to 0.92 Gallon/hour) and maximum output pressure 1 atm (14 psi)
• Manual control for pump priming (defined in setup)
pH alarms:
• High & Low with enable or disable option
• Triggered after 5 sec. if the controller records consecutive readings over or under threshold values
• Level with enable or disable option
• Overtime protection (1 to 180 min. or Off)
