Sand Penetrometer - PN5-S
Instructions
1. The red ring on the barrel of the Sand Penetrometer holds the maximum reading
of the scale for easy reading.
2. Slide the ring down against the instrument handle.
3. Grip the knurled portion of the handle and place the golf ball over the sand that
you will be testing. Ideally sand should be dry and at least four inches thick.
4. Press downward evenly on the sand Penetrometer until the golf ball reaches the
line located at the center of the ball.
5. Read the unconfined strength in Tons per Square Foot or Kilograms per
Centimeter Squared. The reading is located on the lower side of the red ring -
(side closest to the knurled handle).
6. Test an average of three times and disregard results that are too far away from the
average.
