Digital measuring tool for accurate depth checks in workshops and quality inspection. Clear digital readout and robust stainless steel construction make routine measuring less stressful for technicians and hobbyists. Is the Digital Micrometers Ltd Digital Depth Gauge the dependable addition the workshop bench needs?

⚡ At a Glance
  • Measurement Precision: Fine resolution and consistent readings suitable for tight tolerances
  • Best for: Workshop machinists, quality inspectors and hobbyists needing repeatable depth measurements
  • Not ideal for: Tasks that require measuring depths beyond a 150mm range

Simple digital depth gauge built with a hardened stainless steel base for daily shop use. Useful functions include unit conversion, reference memory and automatic power management.


Highly accurate depth checks – with 0.01mm resolution and 0.02mm accuracy

Digital readout reports to 0.01mm (0.0005"), while stated accuracy is 0.02mm (0.001"). Resolution determines the smallest displayed increment, accuracy describes how close readings are to true value.

Enable verification of small tolerances in machining and inspection tasks, giving confidence when checking fits and clearances.

Stable contact and long life – with hardened stainless steel base and 100mm base width

Hardened stainless steel construction resists wear, while a 100mm base provides a broader contact surface to reduce rocking. Metal build outlasts common plastic alternatives under repeated use.

Deliver consistent, repeatable measurements across batches and endure everyday workshop knocks and abrasion.

Faster workflows – thanks to unit conversion, zero setting and reference memory

On-board functions include mm/inch conversion and zero setting at any point, plus a memory that remembers position when power is removed. Auto on and auto off preserve battery life.

Speed up measurement cycles, avoid manual conversions and pick up where left off without re-zeroing or remeasuring references.
