Description
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
- Easy viewing on the large LCD with plant-safe green backlighting
- Calibrate pH and EC with a single Quick Cal solution
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.
The benefits:
- 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 professional
The GroLine Monitor has been developed by growers and scientists who are committed to helping you take your growing operation to the next level.
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.
Professional accuracy
Advanced algorithms and greater pH and TDS/ppm accuracy ensure operational consistency and a finer understanding of your plant’s needs.
1 probe – 3 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.
Quick Calibration
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.
