GroLine Monitor for Hydroponic Nutrients

The GroLine Monitor for Hydroponic Nutrients provides 24/7 pH&EC measurements for consistent yields every time,  a Good Laboratory Practice (GLP) feature for professional accuracy, and the ability to calibrate pH and EC with a single Quick Cal solution.


      Essentials at a Glance

      A large clear LCD displays all of your essential readings so you have continuous information about the state of your hydroponic nutrients solution. High and low alarms will flash a warning if something needs to be adjusted.


      Monitor Change Over Time

      The GroLine Monitor automatically logs results every 15 minutes over a 30 day period. Minimum, maximum, and average values are logged so you can identify when patterns arise and help prevent future problems.


      One Probe - Three Measurements

      GroLine Monitor's 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.


      Less Maintenance

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


      Professional Level Accuracy

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


      Professional Level Measurements 

      The GroLine Monitor is made by growers and scientists who are committed to helping you take your growing operation to the next level


      Product Features 

      • Three 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, the 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
