Encyclopedia > Depth gauge

A Depth Gauge is a device used to measure pressure and display the equivalent depth in water. It is a piece of diving equipment often used by SCUBA divers.


Most modern diving depth gauges have an electronic mechanism and digital display. Older types used a mechanical mechanism and analogue display.


A diver uses a depth gauge with decompression tables and a watch to avoid decompression sickness. A common alternative to the depth gauge, watch and decompression tables is a dive computer. A depth gauge and an oxygen analyser can be used to measure the partial pressure of oxygen of the breathing gas, which is necessary to avoid oxygen toxicity.


Digital depth gauges have the added advantage of indicating the diver's rate of ascent and descent, which can be is useful for avoiding barotrauma.


As the gauge only measures pressure, there is an inherent inaccuracy in the depth displayed by most gauges that are used in both fresh water and sea water due to the difference in the densities of fresh water and sea water.

Depth - Wikipedia, the free encyclopedia (372 words)
Depth most commonly refers to vertical distance below a body of water, or a distance in to the Earth's crust, although it is also commonly used in geometry and physics.
The depth of an impact crater (or other crater) in a solid planet or moon may be measured from the local surface to the bottom of the crater, or from the rim of the crater to the bottom.
Depth "B" measures from the mean height of the rim to the bottom of the crater.
