Hanna HI981420-01 GROLINE NUTRIENT MONITOR AND RELATED PRODUCTS

The HI981420-01 GroLine Monitor automatically records pH/EC/PPM/Temp data for 30 days and provides around-the-clock, continuous monitoring with user set-able alarms.

Quick to setup, simple to use, this monitor was designed with the grower in mind. Make your reservoirs easy to manage with the GroLine Monitor.

  • Trusted - 24/7 pH/EC/PPM/TEMP readings with user set high & low alarms.
  • Simple - Rugged combo probe designed for reservoirs.  
  • Simple - Convenient combo solution to calibrate pH/EC/PPM at once. 
  • Accountability - See the real data behind each calibration with GLP.  
  • Professional - Data logging records min, max, and average values automatically. 
  • Accurate - ±0.05 pH Accuracy.
  • Range - Highest EC/PPM range of any monitor in the market. 

FEATURES AT-A-GLANCE

 

  • 3 sensors combined in a single rugged probe body: pH electrode with renewable cloth junction, amperometric EC/TDS sensor, and an internal temperature sensor for temperature compensated readings
  • IP65 rated enclosure: designed to withstand harsh grow environments
  • Wide pH Range: measure pH from 0.00 to 14.00 pH
  • Selectable EC to TDS/ppm conversion factor: choice of either a 0.5 or 0.7 conversion factor
  • Automatic Temperature Compensation: all readings are compensated for variations in temperature, temperature displayed in oC or oF along with pH, EC or TDS reading
  • Large LCD with plant-friendly green backlighting: LCD can display all three essential hydroponic nutrient measurements at one time, a 3-second cycle of single measurements, or a real-time graph screen with options for measurement selection and log recall
  • Data logging for 30 days: logs every 15 minutes for last 30 days, stores min, max, and average values
  • Data transfer: USB-C port for easy data transfer to memory stick or PC
  • High and low alarms: warns when your nutrient solution is out of desired range by flashing display and message
  • Ambient light sensor: While HI981420 has the correct PAR values to be safe in photo sensitive gardens, auto dimming was added to the monitor as an added safety precaution.
