Can the flow rate for the Orbisphere Luminescent Dissolved Oxygen (LDO) sensors be set lower than the recommended 50 mL/minute when using a flow chamber?
Orbisphere LDO sensor minimum flow rate requirement for the flow chamber.
The LDO technology does not require sample flow in order to make a valid dissolved oxygen measurement. The minimum flow rate of 50 mL/minute is recommended to minimize potential sample line air leak effects on low level dissolved oxygen measurements. The flow rate should be adjusted to minimize the lag time between the sampling point, and where the sample is measured inside the flow chamber.
