Measure oxygen dissolved in water and sewage in % of saturation or mg/l, temperature and atmospheric pressure.

Two kinds of power sources 9V battery or power adapter enable work in field and laboratory.

Air pressure measurement with automatic counting of it’s influence on the oxygen measurement increases the accuracy and makes working easier.

The CCO-401 automatically counts the influence of salinity on the result of dissolved oxygen measurement what greatly shortens the work time.

Wide measuring range enables measurements in lakes with blooming vegetation.

• 1 or 2 point oxygen probe calibration.

• The CCO-401 additionally measures conductivity, the characteristic features identical like in
  CC-401.

• The CPO-401 measures also pH, characteristic features like in CP-401 pH meter.

• Automatic or manual temperature compensation.

• Clock with date.

• Internal datalogger enables storing up to 200 results, taken in series or single with temperature, time and date.

• The results and characteristics are stored in
  non-volatile memory.

• RS-232 output for connecting with a PC or
  with a standard printer using an interface.

• 24 months warranty for the meter 12 for electrodes.•
