Dissolved Oxygen Meters
BI-680 Online Dissolved Oxygen Controller
Industrial online dissolved oxygen controller for continuous monitoring of dissolved oxygen concentration and saturation in water, 1 or 2 point calibration, 4 to 20 mA outputs.
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.
