Hanna HI981421-02 pH/EC/TDS/Temperature Monitor with in-line probe
Calibrate pH and EC with a single solution of Quick Cal
HI1285-9 threaded probe that withstands up to 8 bar of pressure IP68
pH and EC 24/7 for consistent performance at all times
Quick and intuitive reading
A large LCD screen displays all your readings so you know the values of your hydroponic nutrient solution 24/7. Alerts flash to warn you if something needs adjusting.
Continuous measurements
The GroLine Monitor automatically records your results every 15 minutes for the last 30 days. The minimum, maximum, and average values are stored so you can recognize patterns, helping to prevent future problems.
One probe. Three parameters
Our 3-in-1 pre-amplified inline probe measures pH, EC/TDS, and temperature in a unique and durable polypropylene body, making the GroLine Monitor easy to use and set up. The HI1285-9 probe has a 3/4" threaded connection for insertion into a pipe for flow relative to the levels indicated by the monitor.
Quick Calibration
A single calibration solution for pH and conductivity makes calibration quick and ensures all your measurements are accurate every time for better plant care and higher yields.
High Accuracy
Advanced algorithms and increased accuracy of pH and TDS/ppm ensure operability and a better understanding of your plant's nutritional needs.
Measure Like a Pro
Our GroLine Monitor has been designed to help growers easily perform routine nutrient measurements.
