Turbidity
The Turbidity sensor is mounted in the black Delrin bracket adjacent to the fluorometer and
shipped in a rotated position to protect the optical surface. A single screw holds the sensor in the
bracket by squeezing the slotted clamp. Before deployment, rotate the sensor within the bracket to the
desired sampling orientation (do not remove the bracket itself). The clamp will firmly hold the
turbidity sensor when the screw is hand tight; do not over-tighten. When replacing the MMP skin,
guide the Turbidity cable into the notch near the corner of the MMP skin.
NOTE
When the sensors are uncovered, protect the optical surfaces from scratches.

Mechanical Specifications
Each sensor connects to the MMP end cap with a 6-pin Impulse cable. The bulkhead
connectors are labeled and color-coded. The Fluorometer and Turbidity cables are wired identically
and can be interchanged for troubleshooting. Spare cables are available from McLane.
