WATERPROOF pH / CONDUCTIVITY / SALINITY METER CPC-461


The most important features




Detailed description


CPC-461 belongs to the newest generation of meters. It is distinguished by a large 3,2” colour graphic touch screen.

Characteristic features:



In the pH and mV measurement function:


In the conductivity measurement function:


In the temperature measurement function:


Other features:


The standard set includes: ECF-1 conductivity sensor, 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.
