Calibration Specifications
Accuracy of density standards
±0.1%
Accuracy of moisture standards ±4.0%
Calibration range
70-170 pcf density
0 - 40 pcf moisture
Method: Computer reduction of count rate data based on US
National Bureau of Standards Photon Cross Sections, Neutron
Cross Sections, and Absorption Coefficients. Data is reduced to
the form D= (Ln(A/CR + C))/B for density and M= (CR-E)F for
moisture where A, B, C, E, and F are constants and CR is count
ratio.
