The conventional electrodes may be used for indoor applications but
the cable length should not exceed 10 m (33').
MEDIUM DISTANCE, INDOOR/OUTDOOR
INSTALLATION
When an outdoor installation is required, it is normally necessary to
install a transmitter to obtain accurate readings at distances from 10
to 50 m (33-165').
Since the introduction of AmpHel
electrodes these distances are no
longer a problem. You can now connect your meter directly to an
AmpHel electrode, saving the cost of a transmitter.
The standard cable length of the AmpHel electrode is 5 m (16.5').
Additional lengths of regular cable up to 50 m (165'), can be
installed without special connectors. It is recommended to use coaxial
cables due to their excellent insulation, even though, Amphel elec-
trodes can operate with both.
AmpHel electrodes have a micro-amplifier in the electrode cap to boost
the signal, drastically reducing susceptibility to noise and drift.
For more details about these or other specially made electrodes,
consult the Hanna process and water treatment literature, or call the
Hanna Office nearest to you.

As with any other liquid contact measurement, ensure that the probe
is installed in such a way that it permanently lies in the solution
whether in the tank or the discharge pipe.
HI 3001D FOR IN-LINE INSTALLATION
HI 3001D is suitable for this purpose due to its external 1/2” NPT
thread, 6 Bar (87 psi) pressure rating and the short immersion depth
of 20 mm (0.8”). t can be installed in 1/2” pipes (with the aid of a
“T”). For larger pipe sizes, HI 3001D can be mounted upside down or
vertically.
