Models 502 with 60 mm thermal printer.

CX-502 Laboratory multifunction meter with printer, set with temp. probe.
High accuracy and repeatability benchtop meters, powered by 9V power adapter.
In one meter all functions of pH meters, conductivity meters and oxygen meters of series 500 were included.
Models 502 are equipped with 60 mm thermal printer.
The meters enable: - accurate pH measurements in the whole measuring range
(accuracy 0.002 pH), - precise ORP (redox) measurements (accuracy 0.1 mV),

Multifunction meter

Model  Description 
CX-502  Laboratory multifunction meter with thermal printer.

Possibility of conductivity measurements of both ultra pure water and thick salinity.
Accurate conversion of the conductivity to the salinity in NaCl or KCl according to real characteristics.
Counting the TDS from the conductivity measurement.
Atmospheric pressure measurement.
Oxygen concentration measurement with automatic counting of atmospheric pressure and salinity influence.
RS-232 output for a PC and Centronics for standard printer.
Collecting up to 200 results taken in series or single with temperature, time and date in internal datalogger, sending the data to a PC or printing on internal (models 502) or standard printer.
Unification of the operating in all measuring functions make working trouble free. 24 months of
warranty for the meter.
