MULTIFUNCTION pH, ION, CONDUCTIVITY, TEMPERATURE, DISSOLVED OXYGEN

CX-731, CX-732, CX-741 AND CX-742 MULTIFUNCTION COMPUTER METERS
pH, ION, CONDUCTIVITY, TEMPERATURE, DISSOLVED OXYGEN

CX-731 and CX-741 are laboratory meters in benchtop housings.

CX-732 and CX-742 besides work in laboratory may be used in the field (5hrs of continuous work).

CX-731 and CX-732 enable pH, ion concentration, ORP, conductivity and temperature measurements.

CX-741 and CX-742  additionally may measure oxygen dissolved in water.

Exceptionally high accuracy of all functions.

Large back-light LCD display enables observation of the results in graphical or numerical form.

  • 8 point automatic, half automatic or manual calibration of pH and ion electrodes.

  • Automatic or manual temperature compensation.

  • In conductivity meter, ion meter and oxygen meter there is possibility of changing the unit with automatic conversion of the result.

  • In ion meter the molecular weight of measured ion is automatically introduced, this enables determining the results in mol/l, mg/l or pX without the necessity of manual conversion.

  • Possibility of storing single measurements 
    or series with set time interval 
    (10 x 499 results).

  • The results stored in memory may be observed as graphs, parts of them may be cut out and zoomed graphs may be compared.

  • Function of half automatic potentiometric, calorimetric and conductivity metric titration.

  • In oxygen meter manual correction of atmospheric pressure and salinity.

  • Function of small water course flow measurement (streams, small rivers) using conductivity method.

  • CX-742 has received a golden medal on international fairs
