A urinometer is used to measure the specific gravity of urine. It is mostly used in physiology labs, pathology labs, and clinical training. Students fill a cylinder with urine and gently place the urinometer inside. The reading is taken at the urine meniscus level. Helps check kidney function and hydration levels. Useful in diagnosis of diabetes and renal disorders. Simple to use and does not require electricity. Provides quick clinical assessment. Essential in medical student practicals.
