Frequently Asked Questions
Why is the Oxysens sensor considered "maintenance-free"?
Unlike conventional DO sensors, the Oxysens is uniquely designed so it does not require changing of any membrane or electrolyte over its operational life
What applications is the Oxysens DO sensor best for?
It is heavily utilised in water, wastewater, swimming pools, composting facilities, and fish farms
Does flow rate affect the accuracy of the Oxysens sensor?
No, the Oxysens sensor is completely flow-independent.
