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.
