Digital Depth Gages – Precision Tools for Accurate Depth Measurement

A Digital Depth Gage is a high-precision measuring instrument designed to determine the depth of holes, slots, grooves, and recessed areas in various materials. Equipped with a digital display, it allows for quick and accurate depth readings without manual interpretation, making it a go-to tool in machining, metalworking, quality control, and mechanical inspection.

Digital depth gages typically consist of a flat base and a movable probe or rod that extends into the measured feature. With an easy-to-read digital readout and millimeter/inch conversion, they improve measurement efficiency and reduce user error.

Key Features of Digital Depth Gages

Digital LCD Screen

Clear, high-contrast display for easy and accurate reading.

High Accuracy

Provides excellent resolution suitable for precision measurements.

Stainless Steel Construction

Durable, long-lasting material resists wear and tear.

Flat Base Design

Ensures stability and measurement reliability on flat surfaces.

Applications of Digital Depth Gages

  • Metalworking & Machining: Measure hole depths and recesses in manufacturing.
  • R&D Laboratories: Evaluate prototype part depth with precision.
  • Automotive Industry: Check groove and tire tread depth accurately.
  • Aerospace & Defense: Verify drilled holes and countersinks.
  • Manufacturing & QC: Maintain depth consistency across product batches.
  • Tool & Die Making: Measure mold and die cavity depths precisely.

How to Use a Digital Depth Gage

  1. Set Up the Base: Ensure the flat base is on a clean, stable surface.
  2. Calibrate the Display: Power on and zero the gage before use.
  3. Lower the Measuring Rod: Gently insert it into the depth feature.
  4. Read the Value: Observe the measurement on the digital screen.
  5. Repeat for Accuracy: Take multiple readings to confirm results.
