The depth gauge is a simple measuring instrument simply for measuring hole depth or slot depth. Similarly to a caliper, it measuring to 2 decimal places and is a quick and easy tool for gauging depth. Depth gauges are available as digital depth gauges or vernier depth gauges. For more accurate measuring, it is recommended to use a depth micrometer which will measuring to 3 decimal places with a higher level of accuracy. Depth gauges have a measuring bridge which should be placed over a flat surface when you zero the tool. The depth bridge will then straddle the hole diameter or slot width to ensure accurate and stable measuring of the depth.
