Your probes need to
be as far as possible
from any submersible pumps
and where nutrient and
pH solutions enter the tank
2.7 Probe connection and placement
Probes need to be placed close together
in the nutrient tank near where there
is good mixing. This could be near an
agitation jet or a water inlet valve. They
need to be as far away as they can be
from any submersed pumps (this will
minimise interference to your reading)
and away from where the nutrient and
pH solution falls into the tank.
pH and pH ATC (optional)
The Dosetronic Solenoid kit has a
standard pH probe. For a more accurate
pH measurement a pH ATC probe can be
purchased. It connects to two separate
sockets. The sockets are labelled pH
and pH ATC. Together they provide a
temperature compensated reading that is
more accurate than a standard pH probe.
Temperature Probe
The temperature probe can measure the
temperature of either water or air.
The temperature probe must be
measuring what your Dosetronic is
controlling (air temperature or water
temperature).
