Hanna Instruments GroLine Monitor for Hydroponic Nutrients

The Hanna Instruments GroLine Monitor designed for Hydroponic Nutrients is a sure way to track pH, conductivity, and temperature in your hydroponic nutrient solutions.

Whether you use hydroponics, aquaponics, or a traditional greenhouse, this monitor provides 24/7 measurements.

Professional Accuracy

Designed and made by growers and scientists, the GroLine Monitor includes a 3-in-1 pre-amplified probe which measures pH, EC/TDS, and temperature. Encased in a durable polypropylene body, it’s easy to set up and handle.

• Professional Level Accuracy: The GroLine uses advanced algorithms and greater pH & TDS/ppm accuracy which ensures consistency of operation and more finesse in determining nutrient needs.
• Monitor Changes Over Time: Automatic log of results every 15 minutes over 30 days, it stores minimum, maximum, and average values, so you can see patterns and prevent problems.
• Quick Calibration: Possessing a single calibration solution for pH and conductivity, this monitor enables fast calibration, ensuring ongoing accuracy for all measurements.

These professional features result in better plant health and overall yield for growers.

Two Probe Options

The Hanna GroLine Monitor for Hydroponic Nutrients is available with a standard probe or an in-line probe for flow-through monitoring.

• Standard Probe: This multiparameter probe contains a pH electrode with renewable cloth junction, an amperometric EC/TDS sensor, and an internal temperature sensor for temperature compensated readings.
• In–Line Probe: Also a 3-in-1 pre-amplified probe, this measures pH, EC/TDS, and temperature like the standard probe. It has a ¾-inch connection enabling insertion into a pipe for continuous immersion up to 2 meters.

Large LCD Screen

Equipped with a large LCD, easy to read screen, the GroLine monitor displays essential hydroponic nutrients against plant-friendly green backlighting.

These measurements can be displayed with all 3 shown at the same time, in a 3-second cycle of single measurements, or a real-time graph screen with options for individual measurement selection and log recall. Temperature can be monitored and displayed in either Fahrenheit or Celsius.

Additional Features

• Data Logging: Tracks data for 30 days, logging every 15 minutes, it stores minimum, maximum, and average values.
• Data Transfer: The monitor is equipped with a USB-C port for easy data transfer to external drive or PC.
• High & Low Alarms: These will warn you when your nutrient solution is out of desired/set range. The display will flash with a message.
• Ambient Light Sensor: Will automatically dim the LCD display.
• IP65 Rated: This allows the monitor to be safely placed in damp growing environments.
• Wide pH Range: Measure pH in nutrient solutions from 0.00 to 14.00 pH.
• Selectable Conductivity Conversion: Set EC and TDS/ppm measurement conversion factor for 0.5 or 0.7 factor.

Summary

For professional monitoring with accuracy, the Hanna GroLine Monitor for Hydroponic Nutrients can be also used in aquaponics and traditional greenhouse settings. Large LED display offers 3 options for data display plus a flashing alarm when nutrients are out of the desired range. Choose standard or in-line probe.
