Abstract:
     The tester for measuring thickness of underwater deposition and depth is composed of probe and instrument. The probe is sunk down and then inclined when it contacts with surface of deposition. The inclined probe signals operator to mark on post. The instrument gives vibration signals to probe, making it vibrate and continuously sink down. The probe signals operator again when it reaches bottom of deposition and inclined and the operator marks on post again, that is tested depth. The difference between two marks is the thickness of deposition.
