AmpHel
electrodes have a micro-amplifier in
the electrode cap to boost the signal, drasti-
cally reducing susceptibility to noise and drift.
With all of the components sealed in the
electrode body, moisture up to 100% RH will
not effect the signal.
LONG DISTANCE, INDOOR/OUTDOOR IN-
STALLATIONS, ISOLATED OUTPUT FOR
COMPUTER INTERFACE
If your application has a distance greater
than 50 m (165'), it is necessary to install a
transmitter between the electrode and the
meter.
Hanna offers a full line of pH/ORP transmit-
ters with or without LCD displays.
