Depth Digits 300/100 Sensor Digital Depth Gauge, 0-300 mm Range, 0.01 mm Resolution, Stainless Steel, LCD Display

Precision-ground stainless steel and a high-contrast LCD set the Depth Digits 300/100 Sensor apart from conventional depth gauges. While many tools in this class offer only basic measurement, this model combines a 300 mm range with 0.01 mm resolution and ±0.03 mm accuracy, delivering laboratory-grade confidence in field conditions. Its 100 mm hardened base ensures stable, repeatable contact on flat or slightly curved surfaces, and the 3 mm measuring rod reaches into narrow slots and recesses where bulkier tools cannot go.

Highlights

• Wide 0–300 mm (0–12 inch) measuring range for deep recesses, slots, and step heights
• Fine 0.01 mm (0.0005 inch) resolution with ±0.03 mm accuracy for critical tolerances
• Large LCD digital display with clear digits and easy-to-read units
• Instant switching between millimetres and inches—no conversion charts needed
• Zero setting at any position for comparative and differential measurements
• Hardened stainless steel construction resists wear, corrosion, and shop impacts
• Auto power off preserves the LR44 button cell battery for months of intermittent use
• Compact 100 mm base length fits tight setups and portable tool kits

In daily use

Slide the base flat against your reference surface, lower the rod to the bottom of the feature, and read the value directly—no vernier interpretation, no parallax error. The zero button lets you set a reference at any point, so you can measure step heights, groove depths, or differential dimensions without mental arithmetic. The display toggles between millimetres and inches at the press of a button, and the auto-off function extends battery life during busy workdays.
