LABORATORY pH / ION METER CPI-502


The most important features:




Detailed description


CPI-502 measures pH, redox potential (mV), Ion concentration and temperature. Simultaneous observation of the chosen function and temperature after choosing the right button.

Characterisctic features:



In the pH measuring mode:


Ion selective measurement


In the mV and redox potential measurement function:


Other features:



In comparison with CPI-505 the meter has smaller display without backlight. There is no possibility to ”hold” the reading on the display and no information about the reading stabilisation. Does not create calibration reports. No possibility of viewing the electrode's buffer and slope.

The standard set includes CT2B-121 temperature sensor with Pt-1000B resistor, EPS-1 pH electrode for measurements in clean water. It should not be used in other types of liquids. Measurements in liquids with sediments 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 (diaphragma) of the electrode against clogging, ensures stable measurements in these types of liquids or semi-liquid masses, in which other electrodes stop working quickly. When properly handled and mainatined, the electrode's lifetime is longer than the standard electrodes.
