The G series Conductivity
meters are designed as high end conductivity/resistivity measuring instruments
and are capable of fully automating conductometric measuring routines.
These instruments
incorporate a patented electrode sensor technology
which stores critical calibration and ID information in the sensor cell.
This data is then transferred to the meter when the electrode is used
for measurement giving the operator a complete data trail of critical
calibration data as well as meta data for GLP/GMP compliance capability.
Additional features
include interval measuring function, automation cabability for adding
an auto sampler for unattended multiple sample analysis, External Printer
Unit, full RS-232 IO capability and more.
Features:
- Intelligent Sensor
"Calibration Memory" - The electrode stores 10 sets of cell
constant data in a microchip of the electrode including Date, sensor
information, ID, cell type, etc.. The information is downloaded to the
meter when attached.
- GMP/GLP Compliant-
Calibration data storage function (10 sets of data). Sensor replacement
function and alarm indications. Diagnostic messages are displayed when
an error indication is found.
- Easy to read and
use menu driven operation, back lit large LCD display.
- Multiple measurement
Units- conductivity (S/m, S/cm), resisitvity(Ohm*m, Ohm*cm), temp.,and
concentration(%)
- Graphical display-variation
of measured value can be displayed as a graph (time vs. conductivity)
on the LCD display.
- Automatic stability
determination-is automatically determined based on pre-set reference
data depending on sample type.
- RS-232C output-as
standard feature
- Automatic cell
constant determination-by immersing is standard solution (at constant
temp)
- Temperature compensation
adjustable to meet sample conditions- Non linear temperature compensation
available (40G/60G) as well as linear compensation (%/Deg. C), enabling
instrument to provide more accurate temp compensation.
- Data storage function-
up to 100 pairs of measured data can be stored in memory.
- Temperature coefficient
can be calculated automatically (40G/60G) by measuring 2 to 10 points
on conductivity and temperature values of same sample.
- Accurate measurement
for pure water region attainable (CM-60G) with use of conductivity cell
and temperature compensation profiles for pure water.
- Built in thermal
Printer (HM60 models) for auto-print at hold function, average value
print, printing by interval times, and manual print.
- System expandability
(cm60)- optional peripherals can be added such as turn tables (12,18,
or 36 samples) and electrode selector (max 5 electrodes).
5 Models are available
depending upon the options and accuracy that are required.
 The
WM-22EP. a combination pH/Conductivity Meter. 
The CM-20J is the
lower cost economical version for those requiring a basic conductivity
meter without the high end features and automation capabilities.
