Detailed description:


CX-705 multifunction meter belongs to the newest generation of measuring equipment and enables very accurate measurements of:

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:



In the temperature measurement mode:


In the titration mode:


Other features:


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


The case set for CX-705 for the field work

The meter is placed firmly in the case. The accessories – electrodes, probes, cells and power adapter - may be put sideways in the case. The rechargeable batteries are placed in the upper side, they may be charged without taking them out of the case.
