Description
The MA235 is the flagship of the Quattro range combining advanced level ion
concentration and pH measurement in one unit.
The MA235 has all the features of the MP230 advanced pH meter but takes GLP
to a new level. The MA235 can be set-up to enforce calibration after either
a preset time interval or number of samples to ensure compliance with
customer calibration regimes.
Dual electrode inputs and split screen display ensure the two completely
seperate measurement systems are seamlessly combined in a single benchtop
meter.

Features and Benefits
An electrode switch box can be added to either channel allowing connection
for up to five electrodes, making it unnecessary to change electrodes when
switching sampling methods. Calibration data and electrode identification
number (e.g. serial number) for each electrode is stored when setting up
each method. A further aid in set-up is the two-way RS232 port which allows
the MA235 to be set-up remotely from a PC.
The five point calibration ensures a high level of accuracy even at the
extremes of concentration measurement whilst a full range of incremental
techniques, in addition to direct ion measurement, ensures all ISE
applications are covered.
