DESCRIPTION
4.2. GENERAL DESCRIPTION
GroLine Monitor
is designed to offer you the combination of pH, conductivity, (or total dissolved
solids), with temperature measurements. All operations and settings, including calibration buffers
and temperature scale selection, are included in easy to use monitor setup.
The supplied
HI1285‑8
multiparameter probe measures pH, EC/TDS, and temperature in one
convenient, rugged probe. A solid‑state preamplifier is integrated into the probe to protect the pH
measurement from transient electrical noise. Sources of electrical noise include ballasts used in
lighting and pumps to circulate water and nutrient solutions. If pH reading in pH 7 buffer is around
4, the probe is broken.
Measurements are automatically logged in the internal memory of the
GroLine Monitor
every
15 minutes and can be viewed using the plot/record log feature or exported to a Flashdrive or by
connecting to PC.
The main operating modes of this monitor are measurement, setup and logging. Follow this
general outline of steps to get you started. The following topics are expanded in the sections of this
manual.
Other features:
• Can be integrated into a fertilizer system
• pH/EC/TDS probe with built‑in temperature sensor
• As a failsafe feature if the pH bulb breaks the pH will be around 4
• Multiple viewing options for on‑screen data
• Quick calibration using Quick Cal solution simultaneously for pH and EC
• Calibration timeout reminder from 1‑30 days for pH and EC
• Visual plot screens for real‑time data and log history
• 24 hour summary screens (plot and details)
• Alarms feature for all parameters
• Automatic Continuous Logs, 15 minute intervals, 30 day storage
• Logged Data can be stored and later exported to a USB C drive or transferred to a PC
using the USB C connection
• GLP feature calibration data for the pH and EC (up to 5 calibrations)
• Dedicated Help with contextual message
• Setup, Calibration and Operating parameters are stored in nonvolatile memory. All
settings are retained if power is lost.
