The 4630/31 and 4635/36 pH/Redox transmitters and
associated electrode systems have been designed for
continuous monitoring and control of pH. The electrode
system can be standardized to the instrument using the built-
in calibration facility and a single point buffering facility
provides easy re-calibration after initial standardization.
The 4630/31 models are wall- or pipe-mounted instruments
and the 4635/36 models are panel-mounted, DIN sized
instruments. All instruments have a single programmable pH
input channel, and a single temperature input channel. When
making temperature compensated measurements the sample
temperature is sensed by a Pt100 resistance thermometer
which can be mounted in the electrode system.
Models 4631 and 4636 incorporate a water wash facility for
system cleaning. During the wash cycle, the Alarm 1 status
and the retransmission value are held in their pre-cycle
condition.
Instrument operation and programming is via four tactile
membrane keys located on the front panel. Programmed
functions are protected from unauthorized alteration by a five-
digit security code.
