Depth Gauge Fieldmann FDAM 0201 — mechanical depth gauge up to 25 mm, precision measuring tool

Fieldmann FDAM 0201 is a compact mechanical depth gauge for measuring recessed depths up to 25 mm. It is designed for straightforward, handheld measurements of grooves, holes, thread depth and fittings in workshop, woodworking and DIY tasks.

Advantages

The gauge offers simple, reliable depth readings with a clear backlit LCD display and autocalibration for consistent results. Its design includes a replaceable lithium battery for extended use and a measuring range suitable for most small workshop and hobby applications.

Suitable for

• Measuring groove and recess depths in woodworking
• Checking thread and tread depth on tires and mechanical parts
• Verifying hole depths and fittings during assembly or repair
• General workshop and DIY depth measurement tasks

When it may not be suitable

This mechanical depth gauge is intended for manual, short-range measurements up to 25 mm and may not be suitable where longer-range or highly automated measurement systems are required. It is not meant to replace high-precision laboratory instruments for metrology-grade calibration.

Key specifications

• Measuring range: up to 25 mm
• Display: LCD with backlight
• Power: lithium battery (replaceable)
• Autocalibration function for repeated measurements
• Handheld, compact mechanical design

How to use

Switch on the device and allow autocalibration if prompted, then place the measuring base on a reference surface and extend the probe into the recess or hole until contact is made. Read the depth directly from the LCD display. Replace the lithium battery when the display indicates low power and perform periodic checks against a known reference to maintain accuracy.

What to consider before purchase

• Required measuring range — device measures up to 25 mm
• Desired display type — includes an LCD with backlight for visibility
• Power source and maintenance — uses a replaceable lithium battery
• Level of precision needed compared to laboratory-grade instruments

Usage recommendations

For consistent results, clean contact surfaces before measuring, allow the device to autocalibrate on a stable reference, and store it in a dry place. Use gentle, steady pressure when taking measurements to avoid deflection of the probe.
