  • Page 9: Snap 41 - An Overview

    2 Snap 41 – An Overview Snap 41 is a portable alcohol meter for the determination of the alcohol concentration in distilled spirits that can be considered to be binary mixtures of ethanol and water. The concentration determination is based on density measurement by the oscillating U-tube method.

  • Page 10: Measuring Principle

    2.1 Measuring Principle Definition of density The density (ρ) of a sample is defined as its mass (m) divided by its volume (V):  ---- - As the volume changes with temperature, density is a temperature-depen- dent measuring unit. The oscillating U-tube method The sample is introduced into a U-shaped borosilicate glass tube that is being excited to vibrate at its characteristic frequency.
