Depth Gauge Mega 200/100 measuring tool model 1240-200

Depth Gauge Mega 200/100 (model 1240-200) is a precision mechanical depth gauge designed to measure depths, step heights and recesses with repeatable accuracy. The instrument is compact and robust for workshop, inspection and field use, offering a clear scale and a stable measuring rod that allows controlled readings during machining, assembly and quality control operations.

Advantages

The gauge provides reliable depth measurement through a rigid frame and a finely machined measuring spindle that reduces play and improves repeatability. Its compact footprint and straightforward mechanical operation make it suitable where electronic devices are unnecessary or impractical. The visible scale and clear graduations support quick visual checks, while the solid construction ensures consistent performance in typical industrial and workshop environments.

Suitable for

• Checking bore and recess depths in machined parts
• Measuring step heights and shoulder distances on components
• Assembly inspection and fit verification of mating parts
• Quality control tasks in workshops, toolrooms and small production runs

Key specifications

• Measuring range: up to 200 mm with fine-scale subdivisions for 100 mm increments
• Resolution: clear graduated scale suitable for precision visual reading
• Construction: rigid frame with stable measuring rod to minimise deflection
• Operation: manual mechanical action without electronics or batteries
• Form factor: compact footprint for use on benches and in confined workspaces

How to use

Place the base of the depth gauge flat on the reference surface and extend the measuring rod until it contacts the bottom of the feature to be measured. Read the value from the scale where the indicator aligns with the graduated markings. For repeated checks, use a steady motion to lower the spindle and ensure the base stays flat against the reference surface to maintain consistent readings.

Usage recommendations

Store the gauge in a dry place and protect the measuring rod from impacts and corrosion. Clean contact surfaces before each measurement and avoid excessive side loading on the spindle. For the most consistent results, perform measurements at ambient temperature and verify the gauge periodically against a calibrated standard.
