Oxygen dissolved in water and sewage measurement.

CO-502 Laboratory oxygen meter with printer (set with COG-1).
CPO-502 pH / oxygen meter - for laboratory with printer (set with EPS-1 and COG-1).
CCO-502 Laboratory conductivity / oxygen meter with printer.
Laboratory meters in benchtop housing, powered by 9V power adapter.
The 502 models have built in thermal printer (60 mm).
Measure oxygen dissolved in water and sewage in % of saturation or in mg/l, temperature and air pressure.
The meter automatically counts the influence of air pressure on the oxygen measurement.
The CCO meter additionally measures conductivity and salinity, characteristic features like in
CC-501 conductivity meter.

pH / oxygen meter

Model  Description 
CO-502  Laboratory oxygen meter with printer
CPO-502  pH / oxygen meter - for laboratory with printer.
CCO-502  Laboratory conductivity / oxygen meter with printer.

The CPO models also measure pH, characteristic features like in CP-501 pH meter.
The CCO models measure salinity and automatically count the influence of salinity to the oxygen content,
this makes working easier and faster.
Calibration of the oxygen sensor in 1 or 2 points.
Automatic or manual temperature compensation.
Clock with date. Internal datalogger enables storing 200 measurements taken as series or single
with temperature, time and date.
RS-232 output for a PC and Centronics for standard printer. 24 months of warranty for the meter.
