WATERPROOF pH / ORP METER CPR-411


The most important features:




Detailed description:


  • CPR-411 is used for simultaneous pH, mV (redox potential) and temperature measurements.


  • Characteristic features:




    The standard set includes CT2B-121 temperature sensor with Pt-1000B resistor, ERS-2 redox electrode, EPP-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 IJ44A 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 (diaphragm) 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 may be efficient for several years.
