Installation off-line
Place the sensor in a flow chamber and connect the flow chamber to the "OUT" port on the
instrument using a small piece of plastic tubing. The sample is evacuated through tubing attached
the outlet port on the flow chamber.
A flow rate exceeding 20 L/hour (ideally 60 L/hour) is required. After opening the sample valve, wait
at least 30 minutes to ensure all parts in contact with the sample have been well rinsed and that the
optimal thermal equilibrium between the sample, flow chamber and conductivity sensor has been
reached.
