Product details

Dissolved oxygen controller OD7685

OD7685It is a microcomputer based online dissolved oxygen monitoring device for water. Adopting a polarographic film sensor, it has automatic compensation functions for temperature, pressure, and salinity, and is equipped with high and low point control relays, automatic cleaning control relays, and high/Low alarm relay; Corresponding to the measured value0/4-20mAThe output signal can be used forPIDControl and data recording are excellent cost-effective online dissolved oxygen measurement and control instruments.
