MULTIFUNCTION LABORATORY METER CX-505


The most important features:




Detailed description:


CX-505 measures pH, redox potential (mV), conductivity, salinity, TDS, dissolved oxygen in % of saturation or mg/l, atmospheric pressure and temperature.
This meter includes all functions of pH meters, conductivity meters and oxygen meters of the 505 series.
All measuring functions are characterised by a very high accuracy and stability of the measurement.
The most recent model has been modified, what results in offering new functions which make working easier, ensure higher accuracy and fulfil more requirements.

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 CT2B-121 temperature sensor is added.
