Digital densimeter for simple determination of urinary density.
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 plus or minus 2. 5 - 10-4 g/cm-3. For clinical use a determination rate of approximately 60 samples an hour with a precision of 1 - 10-3 g/cm-3 may be reached.
