pH / ION METER CPI-601


The most important features




Detailed description


CPI-601 measures: pH, redox (mV), ion concentration and temperature. The meter enables simultaneous measurement and displaying of ion selective reading for the chosen ion, pH (or mV) and temperature reading.
The results are displayed on a 7” graphical colour touch screen.

Other features:


The standard set includes: CT2S-121 temperature sensor with Pt-1000S 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.
The Ion selective electrodes (ISE) should be bought separately.
