BI-680 Online Dissolved Oxygen Controller
• Economy online dissolved oxygen controller is equipped with a polarographic sensor.
• 1 or 2 points calibration using the air-saturated water or zero oxygen solution.
• Salinity and barometric pressure compensations eliminate the measurement error.
• 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 20mA output, etc.
• Reset function automatically resumes all settings back to the factory defaults.
