LABORATORY pH / ION METER CPI-502


The most important features:




Detailed description


CPI-502 measures pH, redox potential (mV), ion concentration and temperature. Enables simultameous ion selective measurement of chosen ion, pH or mV and temperature. The chosen measuring function may be viewed by pressing an appropriate button. The most recent model has been improved with more possibilities providing easier operation.

Characterisctic features:



In the pH measuring mode:


Ion selective measurement


In the mV and redox potential measurement function:


Other features:



The standard set includes: CT2B-121 temperature sensor with Pt-1000B resistor and EPS-1 pH electrode for measurements in clear water, which should not be used in other types of liquid. Measurements in liquid with sediment should be made with use of IJ44A pH electrode, which enables measurements in various samples of both pure and contaminated liquids and semi-solids. Its unusual construction (“intermediate junction”) protects the real junction (diaphragm) of the electrode against clogging, ensures stable measurements in these types of liquids or semi-liquid mass, in which other electrodes stop working quickly. When properly handled and maintained the electrode may be efficient for several years. The ISE electrodes are chosen individually.

In comparison with the CPI-505 meter, the CPI-502 model is equipped with a smaller display.
