pH, Redox (mV) ion-selective measurements

CPI-502 - laboratory pH / ion meter with printer.
Laboratory meters in benchtop housing, powered with 9V power adapter.
Accurately measure: pH, Redox (mV) ion-selective measurements in , g/l, M/l, or ppm and temperature.
Enable ion concentration measurements of monovalent, bivalent, negative and positive ions.
Meter 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.

CPI-502 meter

Model  Description 
CPI-502  CPI-502 - laboratory pH / ion meter with printer.

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: , g/l, M/l or ppm units with automatic conversion when
changing the units.
Possibility of introducing freely chosen values of ion sample solutions.
