1-channel oxygen analyzer and probe

This complete system will monitor oxygen saturation in sea or fresh water, and regulate to hypoxic/hyperoxic levels with optional accessories.

A large instrument display, two digital relays for valve control, menu-driven settings and an analog output for data acquisition, makes this system user friendly and well suited for a range of lab applications.

Example of hypoxic control: the set point value is compared with the measured value. If oxygen saturation is higher than the set point value, the digital relay activates an (optional) solenoid valve to open for injection of nitrogen gas. When the measured value again reaches a value below the set point, the relay de-activates the valve.
