WATERPROOF pH / CONDUCTIVITY / SALINITY METER
CPC-411


The most important features



Detailed description


Easy in use simple meter of good accuracy.
Measures: pH, mV (redox potential), conductivity, salinity and temperature.

Characteristic features:



In the pH measurement mode:


In the redox (mV) measuring function:


In the conductivity measurement mode:


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 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.
