The Hanna Instruments GroLine pH/EC/TDS & Temp Monitor for Hydroponic Nutrients provides around-the-clock, continuous monitoring of pH, conductivity (EC & TDS), and temperature in hydroponic nutrient solutions. Quick to setup, simple to use, this monitor was designed with Hydroponics, Aquaponics, and Greenhouses in mind. Make your nutrient solution easy to manage with the GroLine Monitor.This Monitor combines 3 sensors 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 allowing you get 24/7 pH&EC measurements for consistent yields every time. Calibrate pH and EC with a single Quick Cal solution providing Good Laboratory Practice (GLP) feature for professional accuracy.
One quick glance is all it takes.
A large clear LCD displays all of your essential readings so you know what your hydroponic nutrients solution is doing 24/7. High and low alarms flash warning you if something needs adjusting.
Monitor changes over time.
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 recognize when patterns arise and help prevent future problems.
One probe. Three measurements.
Our 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 Cal for 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.
Measure like a pro.
Our GroLine Monitor is made by growers and scientists alike who are committed to helping you take your growing operation to the next level.
NOTE: Save all packing material until you are sure that the instrument works correctly. Any damaged or defective item must be returned in its original packing material with the supplied accesories
