WATERPROOF MULTIFUNCTION METER CX-461


The most important features:




Detailed description:

CX-461 belongs to the newest generation of highly accurate measuring devices. The meter is designed for accurate measurements of: pH, redox potential (mV), conductivity, salinity, resistivity of the measured liquid, oxygen dissolved in water or oxygen saturation in the air, atmospheric pressure and temperature.
It is distinguished by a large 3,2” colour graphic touch screen.
It is possible to choose a version with GXZ-3tk multifunction (multiparameter) head with electrodes for simultaneous measurement of three different functions (e.g. pH, conductivity and oxygen dissolved in water with temperature) or version with single electrodes. The models have different connectors.

Characteristic features:


In the pH measurement function:


In the mV and redox potential measurement function:


In the conductivity measurement function:


In the oxygen measurement function:


In the atmospheric pressure measurement function:


Other features:


The additional equipment schould be chosen by the user depending on the predicted parameters which will be measured and type of measured solutions.
In standars set the CT2S-121 temperature sensor with the Pt-1000S resistor added.

Affordable price taking into consideration the technical features, acuarcy and additional features.
