Why doesn’t the In-Situ RDO require stirring?
Breakthrough RDO technology does not require stirring because oxygen is not consumed during the measurement reaction. Older technologies and methods require stirring and sample flow. Unlike other optical (luminescence) DO sensors, the In-Situ RDO sensor had no observed differences in analytical results or stabilization times between stirred and non-stirred samples. This enabled the ATP approval of both stirred and non-stirred methods.
