LABORATORY pH / CONDUCTIVITY / SALINITY METER CPC-505


The most important features




Detailed description:


A device of high accuracy, which measures: pH, redox potential, conductivity, resistivity, salinity, TDS and temperature. The currently offered model has been modified and is equipped with new functions which make working easier and ensure higher accuracy.

Characteristic features:



In the pH measurement function:


In the conductivity measurement function:


In the redox (mV) measuring function:


Other features:


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