What is a depth gauge used for?
A depth gauge is an instrument for measuring depth below a reference surface. They include depth gauges for underwater diving and similar applications, and engineering instruments used to measure the depth of holes and indentations from a reference surface.
How do you use a digital depth gauge?
Step4: Push the ruler of the depth gauge all the way down until the measuring surface touches the bottom of the item being measured thoroughly. Step5: Tighten the clamping nut of the depth gauge. Step6: The tool is withdrawn and the reading taken directly from the large LCD display screen.
How accurate is a depth gauge?
The accuracy of Depth Gauge is 0.01 mm which is fair enough for linear measurement and also accurate than vernier caliper. You can choose Digital Depth Micrometer, in order to simplify observation only. Both types of Depth Micrometer delivers the same accuracy.
What does depth gauge mean?
: a gauge for measuring the depth of holes, grooves, or concavities.
How do submarines measure depth?
The way that a submarine, or any other vessel, reads the ocean floor depth is by a fathometer. This device sends a sound pulse to the bottom and calculates the time it takes to bounce back to the boat and converts it to feet or fathoms.
What is a depth gauge called?
depth finder, also called echo sounder, device used on ships to determine the depth of water by measuring the time it takes a sound (sonic pulse) produced just below the water surface to return, or echo, from the bottom of the body of water.
What is the least count of depth gauge?
Least Count of Depth Gauge The least count of digital type depth gauge is 0.01 mm.
What are the limitations of depth gauge?
Disadvantages: requires skill in handling and in reading the results. dedicated gage can not be used for other purposes.
