B. Chlorine sensor
C. Inlet
D. Drain
A ¼-in. OD tubing compression fitting is provided for the sample inlet. If
desired, you can remove the compression fitting and replace it with a barbed
fitting. The fitting screws into a ¼-in. FNPT check valve. The check valve
prevents the sensor flow cell from going dry if sample flow is lost.
The sample drains through a ¾-in. barbed fitting.
1. Attach a piece of soft tubing to the fitting and allow the waste to
drain to open atmosphere.
Important
Do not restrict the drain line.
