Rotational Penetrometers are available for purchase through Beneficial Designs, Inc.
In court cases regarding playground surfacing, the National Center on Accessibility has investigated surfaces using the Rotational Penetrometer to convey the presence or lack of firmness and stability.
has been found to have limitations in its use, but Mulqueen et al.
Rind strength can easily be measured as the force required to puncture the rind with a needle with a rind penetrometer
(Sibale et al.
THE Curragh racecourse is experimenting with the use of a penetrometer
to help determine the state of the ground at different points on the track, writes Tony O'Hehir.
Soil cone penetrometer
measurements must be carefully spaced to prevent interference with each other.
measurements were taken at four depths (0, 3.
1991), in future versions of commercially available penetrometers
may help to overcome these problems.
EP542 describes penetrometers
, soil measurements and statistical treatment of problematic measurements.
Contrary to the vertical penetrometer
, which enables only point measurements of the soil strength, horizontal penetrometer
can make instantaneous measurements during driving.
1992) described use of a modified electronic rind penetrometer
to measure stalk strength and found a highly significant correlation between SCS and rind penetrometer
resistance (RPR) with a CV of 10.
resistance was adjusted for EH at each environment generating a new trait, RadjE, as follows: Radj[E.
