01 / MEASURE WITH CONFIDENCE

Every Specimen Has Its Own Story. Record the Details.

From a newly collected quartz point to a carefully cataloged amethyst cluster, accurate dimensions help you organize, compare and document the pieces that make your collection unique. The oravunel™ MeasureMark Digital Caliper brings a clear digital readout and a familiar 6-inch measuring format to your mineral workspace.

Use the measuring jaws to check exterior dimensions, the smaller inner jaws to measure accessible interior openings, and the depth rod to gauge suitable recesses. With inch and millimeter readings, it is a practical desktop tool for mineral collectors, rock enthusiasts, lapidary hobbyists and specimen cataloging.

02 / DESIGNED FOR YOUR COLLECTION

Useful Details, Thoughtfully Combined

01. Stainless Steel Measuring Jaws

The measuring jaws are made of stainless steel, providing a firm measuring surface and corrosion resistance for routine handling. Use the exterior jaws for specimen width and thickness, the interior jaws for accessible openings, and the depth rod for appropriate recessed measurements.

02. Stainless Steel Beam with Dual Scales

The stainless steel beam carries clearly marked metric and inch graduations. These reference markings provide a convenient visual scale alongside the digital readout, helping you check dimensions while recording measurements in your collection notes.

03. Easy-to-Read Digital LCD

The electronic display presents measurements in large, high-contrast digits for convenient reading at your workbench. The ZERO button allows the display to be reset at a chosen reference point, making comparative measuring tasks easier to organize.

04. Durable ABS Digital Housing

The digital display housing is constructed from ABS plastic. Its lightweight, textured casing provides a practical grip around the electronic controls while keeping the tool comfortable to handle during routine specimen cataloging.

05. Smooth Thumb Wheel & Locking Screw

The thumb wheel helps move the sliding jaw in small, controlled increments. The locking screw can hold the slider in position when you need to retain a measurement for reference or compare a specimen with your notes.

06. Convenient Inch / Millimeter Switching

Switch between imperial and metric units using the dedicated mm/inch button. Whether your catalog uses inches, millimeters or both, this feature makes it easier to keep measurements consistent across different specimens and collection records.
