1. Cut about 3/4 of the way through the PVC pipe about 1.5" from the end.
2. Use metal shears or any other cutting tool to leave the tab of PVC attached to the pipe.
3. Gently bend the tab to about a 45 degree angle, and drill a hole for the screw.
4. Mount the PAR meter with the screw, and use zip ties to hold the cable in place.
5. Enjoy taking PAR measurements without getting your hands wet!
