Rosscraft Centurion Kit - Precise Anthropometric Measuring Tools

Under the direction of Dr. William Ross, the Research and Development division of Rosscraft has worked for over 30 years to improve and refine anthropometric tools. The Centurion Kit provides users with innovative and durable measurement devices that reflect a professional consensus on what is required for comprehensive anthropometry.

The Rosscraft line of Campbell calipers are named after the late Mr. Robert Campbell, the inventor of the double siding branch principle, an exclusive Rosscraft design feature under US patent No. 4265021. To our knowledge, it is the only caliper on the market with long branches that do not bind under pressure at the tips. This allows for consistent pressure along the branches, resulting in the most accurate measurements possible. The Centurion Kit includes the Campbell 10 for small-bone measurements, and the Campbell 20 for larger.

Campbell 20 torso breadths such as acromial, transverse chest, and biiliocristal are obtained with straight branches. AP Chest and some head measurements are made using the AP Extension or Branch Pointers with olive tips. These are exactly 10 cm each (and can be calibrated using the adjustable screw and lock nut). Thus, the caliper reading from AP branch tips will be 20 cm too large (easily corrected by subtracting 20 cm constant in the data entry program or spread sheet).

Rosscraft's commitment to innovation is further seen in their Segmometer 4, included in this kit. The company's researchers originally created this segmometer using basic carpenter's tape, rubber bands, cotter pins, and glue. They discovered that this simple model was a better predictor for height and segmental lengths than an anthromometer, and its use is now standard. The Rosscraft model uses only a flexible tape instead of a bulky housing, with precision-machined base and slider indicators. Rosscraft's segmometer sets a new standard for precision.

The Headsquare included in the kit also reflects the company's responsiveness to the needs of professionals. A cumbersome stadiometer may be impractical in many situations. The solution is the Headsquare, which consists of a headboard and a retractable measuring tape, making it easy to measure both standing height and sitting height.

Rosscraft created the Slim Guide skinfold caliper, also included. The traditional Harpenden caliper is an available option with this kit, but you'll likely prefer the more economical and far more durable Slim Guide, made from ABS plastic.

 

Rosscraft has even improved upon anthropometric tape. To help with orientation and reading, they've added a patch zero indicator and notch.

Finally, the kit includes guides to assist you in your use of the tools. There is an interactive textbook, which you can download for access to thousands of graphs, links, and illustrations. The kit also contains a Power Point CD to instruct you in the correct use of each instrument.
