The model 17405 provides a rapid and accurate determination of lung Residual Volume for the purpose of body composition analysis. It is based on our new "Tri-Gas" analyzer and uses the method of nitrogen washout.

This technique, when combined with hydrostatic weighing, is considered to be the Gold Standard in body composition determination. Perfect for accurate Residual Volume and FRC Measurements.

May also be used for Total Lung Volume using larger rebreathing balloon.
