Depth micrometer, measuring range 0-4 inches, resolution 0.001", accuracy 0.0002".

Vernier scale surface chrome-plated, precise scale, easy to read, with Ratchet Thimble and locking fixture to ensure accuracy.

The Rod and scale are ground, hardened, and ground to improve durability and accuracy for measuring the depth of any shape with steps, grooves, or slits.

The gauge is usually in the form of sliders that move on the measuring beam or Rod by hand to the appropriate position and then adjust with calibration screws.

The gauge position is at the top of the shape of the depression to be measured, and the beam or bar extends to the bottom of the depression to determine the measurement value.
