LABORATORY pH / ION METER CPI-505


The most important features




Detailed description


CPI-505 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 a proper button.

Characteristic features:



In the pH measuring mode:


Ion selective measurement


In the redox potential measuring mode:


Other features:


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 liquid. Measurements in liquids with sediments should be made with use of IJ-44A 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 maintained, the electrode's lifetime is longer than the standard electrodes.
