CPI-501 AND CPI-502
LABORATORY BENCHTOP PH ION METERS
|
|
|
Laboratory
meters in benchtop housing, powered with 9V power adapter.
Accurately
measure: pH, Redox (mV) ion-selective measurements in pX, g/l, M/l,
or ppm and temperature.
Enable
ion concentration measurements of monovalent, bivalent, negative and
positive ions.
|

|
-
May
cooperate with all ion selective electrodes (ISE) chosen depending
on the kind of measured ion equipped with BNC 50 connector.
-
Depending
on the kind of used pH electrode may be used for clean water,
sewage, soil measurements etc.
-
The
CPI-502 meters have
built in thermal printer.
Meter stores independently 3 characteristics of pH electrodes and
3 characteristics of ion selective electrodes.
|
|
|
|
|
-
Calibration
of the electrode:
1 ÷ 5 points.
-
Automatic
pH buffer detection,
their value may be set by the user.
-
Automatic
correction of the temperature influence on sample solution (NIST)
value.
-
Automatic
checking of the condition of electrode’s membrane.
-
In
ion meter possibility of measurement in: pX, g/l, M/l or ppm units
with automatic conversion when changing the units.
-
Possibility
of introducing freely chosen values of ion sample solutions.
|
-
Automatic
and manual temperature compensation.
-
Internal
clock with date.
-
Internal
datalogger for up to 200 sets of results collected in series or
single with temperature time and date.
-
The
results and calibration data are stored in
non-volatile memory.
-
RS-232
output for connecting with a PC and Centronics for standard printer.
-
24
months warranty for the meter, 12 for the electrodes.
