Hanna Instruments GroLine Monitor for Hydroponic Nutrients – HI981420

The HI98142X GroLine Monitor for Hydroponic Nutrients continuously monitors pH, conductivity (EC & TDS), and temperature in hydroponic nutrient solutions around the clock.

This monitor was created with Hydroponics, Aquaponics, and Greenhouses in mind. It is simple to set up and use. The GroLine Monitor makes it simple to manage your nutrient solution.

GroLine helps you grow better.

Get pH&EC measurements 24 hours a day, seven days a week for consistent yields every time.
Professional accuracy is ensured by the Good Laboratory Practice (GLP) feature.
With a single Quick Cal solution, calibrate pH and EC.

Category: Groline

Description

groline monitor display

One quick glance is all it takes.

A large clear LCD displays all of your essential readings so you know what your hydroponic nutrient 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.

Two probes to choose from.

HI98142X is available with a standard probes (left) or one with a 3/4″ threaded connection for insertion mounting.

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.

Features at-a-glance

3 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 growing 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

Data logging for 30 days: logs every 15 minutes for the last 30 days, stores min, max, and average values

Data transfer: USB-C port for easy data transfer to memory stick or PC

High and low alarms: warns when your nutrient solution is out of desired range by flashing display and message

Ambient light sensor: for automatic LCD dimming
