WATERPROOF pH-METER CP-401


The most important features



Detailed description

Designed for highly accurate pH, redox potential and temperature measurement.

Characterisctic 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 liquids. Measurements in liquids with sediments should be made with use of IJ-44A pH electrode, which enables measurements in various samples of both clan 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 mass, in which other electrodes stop working quickly. When properly handled, the electrode's lifetime is longer than the standard electrodes.
