A typical urinometer

A Urinometer is a simple piece of equipment for determining urine specific gravity.

A typical urinometer is composed of a float, a weight, and a stem. The float is an air-filled glass tube, ending in the weight on the left and the stem on the right. The weight is a bulb filled with ball bearings embedded in a red solid, probably a glue of some sort. The glass stem extends to the right, and has calibrated graduations and numbers marked off to indicate specific gravity measurements.

It is placed in a tube of urine, and where the meniscus of the urine reaches displays the specific gravity of the urine.

A urinometer is typically used in medical diagnostic labs.

• Measurement of specific gravity as a surrogate for urinary flow rate--a singular study.

• Sherwood RJ.AbstractAbout two hundred and fifty urine samples were collected some years ago in the course of experimental exposure of one individual to benzene vapor. Phenol concentrations and specific gravities were recorded, together with the volume of urine samples and the times of voiding. Review of this data shows that the reciprocal of specific gravity minus unity (SG-1) measured by refractometer correlated closely with urinary flow rate, while those using the traditional urinometer correlated much less closely. If this is valid for all workers, then refractometer measurement of specific gravity may be used as a surrogate for flow rate. More consistent interpretation of spot urine sampling results as a measure of intake of hazardous substances through occupational exposure is then possible. This is particularly the case if used in conjunction with the formula developed and tested by Araki et al. for flow rate adjustment.
