Features:

• Economical online dissolved oxygen controller is equipped with a polarographic electrode.

• 1 or 2 points calibration using the air-saturated water or zero oxygen solution.

• Salinity and barometric pressure compensations ensure the accurate DO measurement.

• Automatic temperature compensation eliminates the measurement error.

• Setup menu allows setting the number of calibration points, measurement unit, alarm limits, hysteresis value, 4 to 20mA output, etc. • Reset function automatically resumes all settings back to the factory defaults.
