Introduction:

Industrial online dissolved oxygen controller, 1 or 2 point calibration, 4 to 20 mA outputs, the meter is suitable for monitoring dissolved oxygen concentration and % saturation in water.

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 eliminate measurement errors.

Automatic temperature compensation ensures accurate readings over the entire range.

Setup menu allows setting the number of calibration points, measurement unit, alarm limits, hysteresis value, 4 to 20 mA output, etc.

Reset function automatically restores all settings to the factory defaults.
