10 METERS (33 FEET)
DRY ENVIRONMENT

RELATIVE HUMIDITY
MAXIMUM 10 METERS
SHORT DISTANCE, INDOOR INSTALLATION
Due to the low current involved, a very high
grade of insulation is required.
A dry environment is needed in order to ob-
tain a level of insulation not lower than 10
12
Ω.
This type of connection is very delicate and
requires constant attention to maintain proper
operating conditions.
The conventional electrodes should be used
in indoor applications only, and should not
use a cable longer than 10 m (33').
MEDIUM DISTANCE,
INDOOR/OUTDOOR INSTALLATION
When an outdoor installation is required, it is
necessary to install a transmitter to obtain
accurate readings at distances from 10 to
50 m (33-165').
Since the introduction of AmpHel
®
these dis-
tances are no longer a problem. You are now
able to connect your meter directly to an
AmpHel
®
electrode, saving the cost of a trans-
mitter or costly coaxial cable.
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
