INSTRUMENTS - Pg 2

Rosscraft offers the following complete kits, Centurion and Tom as well as additional individual instruments

Tom Kit

Any product or practice can be improved. Rosscraft is responsive to scientists and health professionals.  The Centurion Kit reflects a consensus of what is required for comprehensive anthropometry for individual and team deployment.  

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 manufactured in the world that has long branches that do not bind under pressure at the tips.

1. Tommy 3 small bone caliper, 15 cm, based on inverted “T”   principle.  It is an alternate instrument to the Campbell 10. (it replaces the popular entry level professional Tommy 2 caliper used extensively for somatotyping).

2. Anthropometric tape is a steel flexible tape with a filed notch and patch zero indicator to provide a better reading interface than a single zero line since the interface has no area.  The notch helps orient the tape and align on the interface. 

Technical note: in the preferred technique, the tape is always held in right hand by digits 4 and 5; digits 1 and 2 are the snubbers; digit 3 for pinning, leveling or and adjusting tape perpendicular to the long axis.

The scale on the obverse side is a diameter scale, the increments enlarge by 3.14... times the incremental circumference or linear scale values, e.g., 30.0 cm circumference girth is about 9.5 cm in diameter. The diameter scale has no apparent use in anthropometry as it has in the forest industry for assessing diameters of tree trunks and rolls of paper.

3. Slim Guide Skinfold Caliper.  

(Slim Guide Skinfold Caliper and Harpenden Skinfold Caliper)

The Slim Guide skinfold caliper is an inexpensive alternative to the Harpenden  caliper. It yields approximately similar results and its rugged ABS plastic construction, with high quality springs, guarantees a long life of usage. In the hands of a trained anthropometrist, skinfold calipers percent technical errors of measurement for a single replication as low as 5% depending on training and technique.

Rosscraft markets both calipers. The Rosscraft Slim Guide calipers are black with a silver scale. It is also available in white with a black scale. They have a similar dynamic action to calipers costing over fifteen times as much.  Made from high impact ABS plastic, the Slim Guide can be dropped without damage.  It is so indestructible we can ship in a manila envelope with no extra padding. The scale of 0 to 85 mm is especially useful in assessing skinfolds at the upper ranges, that are not accommodated by most other calipers.  Accuracy may be interpolated to 0.5 mm. There are grants for quantity purchase of Slim Guides for courses and projects.

9. Anthropometry Fundamentals CD - A power point based guide to measurement techniques. Features over the shoulder viewpoints, explicit images and detailed instructions. Techniques consistent with the standards of the International Society for Kinanthropometry. This is a learning system for the new generation of computer oriented students, human biologists, physicians, sport dietitions, physical educators, lifestyle enhancement and other health professionals.
