DESCRIPTION
Main Features
• Easy to read LCD display with intuitive, color-coded backlight
• Automatic Temperature Compensation: all readings are compensated for variations in temperature.
Temperature is displayed in °C or °F along with EC or TDS reading. The EC probe contains an
integral temperature sensor to simplify installation.
• Configurable EC to TDS/ppm conversion factor. Most commonly a TDS factor of 0.5 is used for 0 to
5000 ppm (500 CF) or a TDS factor of 0.7 is used for 0 to 7000 ppm (700 CF).
• High and low alarms: warn the user when the nutrient solution is out of desired range by blinking
the LCD backlight red, disabling the pump, and deactivating the alarm relay
• Built-in peristaltic pump with On/Off or Proportional control
• Manual control for pump priming
• Overfeed protection using the overtime safety timer
• Resumes dosing on restart in case of power failure
• IP65 rated enclosure designed to withstand harsh environments
• Level input to stop control when nutrient levels are low
• Wall-mounted design
• User selectable languages
• Extremely easy to calibrate and use (prepackaged calibration standards)
The
HI981413
Groline Nutrient Dosing System is designed to ensure smooth, safe and efficient
nutrient use in growing operations and to grow healthy plants economically.
