Dissolved Oxygen Meters

BI-680 Online Dissolved Oxygen Controller

Industrial online dissolved oxygen controller, 1 or 2 point calibration, 4 to 20 mA outputs, the meter is suitable for monitoring the concentration of dissolved oxygen 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 the 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 resumes all settings back to the factory defaults.
