Provides Accurate Measurement of Subcutaneous Tissue
TIPS adjust for parallel measurement of skinfolds. There is an easy-to-read
scale, and spring-loaded levers provide a substantially constant
standard pressure of 10 gm./ sq. mm. over the entire operating range.
Each unit is supplied with an individual case.
The fact that body components vary widely in their percentage relationship
to total weight is the fundamental limitation to interpreting body
weight. If the real problem is obesity rather than mere overweight,
overweight and fatness must be dissociated to be understood properly.
most direct,simple, and accurate method for estimating leanness-fatness
is measuring the thickness of skinfolds by constant-tension calipers.
The Lange Skinfold Calipers manufactured by Beta Technology are
specifically designed for the simple, accurate measurement of subcutaneous

tips adjust automatically for parallel measurement of skinfolds,
and rectangular faces with well-rounded edges and corners assure
patient comfort. The face area is approximately 30 square mm. An
easy-to-read scale permits reading up to 60 mm. Accurate to +/-
1 mm. Spring-loaded levers provide a substantially constant standard
pressure of 10 gm./sq. mm. over the entire operating range. All
critical pivot points utilize low friction bearings to maintain
accurate tip pressure at all jaw openings. The caliper is of sturdy,
light-weight construction, and is anti-corrosive. Each unit is supplied
in an individual case.
is important to use calipers in which the pressure is built into
the instument itself and is relatively constant from reading to
reading and over the range of skinfold thicknesses studied. Early
models of calipers were unsatisfactory in that spring-loaded tension
was very low at small openings but increased rapidly as the jaws
of the calipers were opened.
has shown that caliper pressure of about 10 gm./sq. mm. is preferable
to a very low or very high pressure and that it be constant over
a range of openings from two to at least 40 mm. For the purposes
of standardization, this pressure that has been recommended irrespective
of the design of the caliper itself, with a contact surface from
20-40 sq. mm., depending on the shape of the surface.
obtained with skinfold calipers has been found to agree with measurements
obtained from roentgenograms of soft tissues. In turn, these determinations
of subcutaneous fat have been correlated with calculations of total
body fat obtained by other methods.
measurements, especially when combined with limb circumferences,
permit finer discrimination between soft tissue sites than is possible
from inspection. Such discrimination is advantageous in diagnosing
individual nutritional status.
