GENERAL OPERA
TIONS
The
GroLine Monitor
and probe can be used for fertilizer tank monitoring. The system continuously
measures the EC and pH of the tank.
The probe (
HI1285‑8
or
HI1285‑9
) should be placed in a location representing the bulk properties
of the tank.
5.2. CONNECTING THE PROBE

probe to the DIN socket on the bottom of the
monitor by aligning the pins and pushing in the plug. Tighten the nut to ensure a good connection.
Remove the protective cap from the probe before taking any measurements.
Do not be alarmed if salt deposits are present!
This is normal with electrodes and they will disappear when rinsed with water.
