Full Description Specification Manuals

Provides 24 hour monitoring, the GroLine Monitor automatically logs your results every 15 minutes over the last 30 days. Minimum, maximum, and average values are stored so you can recognise when patterns arise and help prevent future problems.

Make your nutrient solution easy to manage with the GroLine Monitor and combined pH/EC/Temperature probe. Quick to setup and simple to use, the monitor was designed for hydroponics, aquaponics, and greenhouses.

Benefits include:

  • High and low alarms with LED indicator: warns when process is out of desired range by flashing display and message
  • Easy viewing on the large LCD with plant-friendly green backlighting: meter displays a clock tag that will disappear when the reading has achieved stability
  • Calibrate pH and EC with a single Quick Cal solution
  • 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 growing 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
  • Ambient light sensor: for automatic LCD dimming
  • Automatic Temperature Compensation: all readings are compensated for variations in temperature, temperature displayed in °C or °F along with pH, EC or TDS reading
  • 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

Giving growers the green light!

The revolutionary HI-981420 GroLine monitor emits just the right amount of green light from its screen so not to disturb the seedlings' natural growing cycles.

Green Light technology

The benefits of having a gentle green glow:

  • Works alongside favoured red and blue lighting systems
  • Does not disturb the plants' 'night sleep' cycle
  • Natural growth regulator
  • Can repress the growth of algae and fungus

Measure like a pro . . . !

The GroLine Monitor has been developed by growers and scientists who are committed to helping you take your growing operation to the next level.

Easy viewing screen

At a glance . . .

A large clear LCD shows all of your essential readings so you know what your water is doing 24/7. High and low alarms flash to warn you if something needs adjusting.

Large LCD shows essential readings

Professional accuracy

Advanced algorithms and greater pH and TDS/ppm accuracy ensure operational consistency and a finer understanding of your plant’s needs.

One probe. Three measurements

The 3-in-1 pre-amplified probe measures pH, EC/TDS, and temperature in a single, durable, polypropylene body making the GroLine Monitor easy to handle and easy to set up.

3-in-1 pre-amplified probe

Quick Cal . . .

A single calibration solution for pH and conductivity makes calibration fast and ensures all of your measurements are accurate resulting in better plant health and better yield.
