Before we started building, we had to lay everything out and draw it on the paper to get a to-scale model of the turbidity monitor. Pieces were then properly labeled so we knew which pieces belonged where.

After the full-scale drawing was complete, we used the measurements provided to cut the PVC pipe to length. This took a lot of precision as any more or less would affect the reliability of the turbidity monitor.

Once the PVC was all cut to length, we started a dry assembly, where we put all the parts together without glue and primer to make sure everything was cut properly and fitting correctly.

After the dry assembly, we marked the lines where the PVC pipe met the housing for the sensors. This was so that when it was being glued, we could get a rough estimate of how far to slide the PVC in and could make small adjustments from there.

Once the lines were drawn and everything was correct, we took the sensor apart and primed the pieces, then glued it together. This took time and precision since you only had about 20-30 seconds to make any sort of adjustments before the glue was dry and in place.

This is the final product of the turbidity sensor. The gray pieces shown are the housing for the wires for the lights and sensors. There is PVC pipe connecting these housings together, which will serve as protection to the wires that will run from housing to housing.
