The most important features

Detailed description

CP-661 Is distinguished by a large a 5” colour graphic touch screen.
The meter can be used for accurate measurements of pH, mV and temperature.
This pH meter enables simultaneous measurements displaying and storing of 2 functions (pH and temperature).

Other features:

The standard set includes CT2S-121 temperature sensor with Pt-1000S resistor, EPS-1 pH electrode for measurements in clear water. It should not be used in other types of liquid. Measurements in liquid with sediment 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.
