METTLER TOLEDO DE40/50/51 Density Meter 89
Annex 1: Density table of dried air
The density of dried air at a specified temperature t and a atmospheric pressure of
760 mm Hg is calculated according to the following formula:
d (g/cm
3
)=
0.0012932
x
p (mm Hg)
1 + 0.00367 x t (°C) 760
The values stored in the instrument are listed in the table below. Intermediate values are
interpolated according to the LaGrange polynomial.
