The Thermophysical Properties Measurement Laboratory (TPML) the inclined piston |
 |
|
The inclined piston vapor pressure equipment is used to measure vapor pressures in the region 0.01 to 30 mm Hg and temperatures ambient to 600 K. Absolute pressure measurements are made, which depend solely on the angle of inclination, the mass of the piston, and the value of g the acceleration due to gravity at that position on the earth. |
