Vogel Electric Digital Depth Gauge is used to measure blind holes that are too small to be measured with a micrometer depth gauge or a regular caliper.

It is especially useful in parts where there is no way to measure the depths due to the small hole size. Also has measuring bridges to slide caliper across the bridge.
