Technical Note: Digital Densimeter for Simple Determination of Urinary Density

Abstract

Juul, A. Digital Densimeter for Simple Determination of Urinary Density. Scand. J. clin. Lab. Invest. 35, 189–191, 1975.

Urinary density can be determined by measuring the change in the natural frequency of a hollow oscillator when filled with liquids of different density. The method requires only 0.6 ml of sample, and the precision is ± 2.5.10⁻⁴ g/cm³. For clinical use a determination rate of approximately 60 samples an hour with a precision of 1.10⁻³ g/cm³ may be reached.

Key Words:

• Densimeter
• density
• urinary
